Twelve layers of chocolate cake filled with alternating layers of silky chocolate pastry cream and rich fudgy chocolate frosting. This 6-inch tall mega cake might just be the best chocolate cake youll ever taste.
With how much Ive missed you and my immeasurable appreciation for you? or by how unbelievably delicious this cake is?
By thanking you for the love, support and patience youve given me duringmy year-long blogging break? Or get emotional at the excitement and encouragement you showed when you knew that Im coming back with more?
I have so much to say to you right now, so much to express, that if I startIm afraid you wont hear the end of it.
Im currently feeling all the feels, but can best sum it up by shouting so loudly: YAY!
YAY! for being blessed with such incredible, understanding readers like yourself. YAY! for regained health and balance. YAY! for a new beginning and YAY! for coming back to this little corner of the internet that holds a special place in my heart. YAY! to you for visiting here again and YAY! for proof that love and empathy still exist in the world.
I dont know about you, but I say this calls for a celebration. And whats celebration without cake?!
And not just any cake. Oooooh noThe real beauty of this cake,like so many things and people in life,does not come from the outsidebut it is whats on the inside that counts.
This beautiful monster is made up of 12 layers of chocolate cake and 12 layers of filling. YES! TWELVE! One layer for every month that I didnt post on the blog! I mean I had to make up for the lost time, right?
Well, technically its a 24 layer cake; 12 cake and 12 filling, but I didnt wanna call it that because it wouldnt have been a fitting title for the situation.
It also took me all 12 months to make! LOL! Just kiddingway more actually 😜
In all seriousness though, this cake is a lifetime of baking in the making. For years and years, Ive been making, testing, eating, tweaking, and retesting chocolate layer cakes in search for that melt in the mouth chocolate bliss that we secretly dream about shoving in our mouths with our bare hands. You knowa tall chocolate cake as sinful looking as the oneBruce Bogtrotter from the movie Matildadevours in one sitting. A moist, multiple layered chocolate cake, slathered with heaps of creamy, glossy chocolate frosting, that doesnt require a tall glass of milk to slide it down the throat.
A dosage of inspiration fromthis one, coupled by a strong cheat day craving and this cake was born! The one I could deem ULTIMATE! The dream chocolate cake Ive been searching for. THIS. IS. IT. for me. My favorite chocolate cake in all the land. And I have a feeling it will become yours too.
In all honesty though, how many of you had wished of being in Bruces place?
This cake does not look one bit like the one in the movie, but the taste and textural experience is exactly how Ive always imagined it to be.
Im sorry for those who hate the word moist but theres really no better adjective to describe it. I mean the cake makes a moist sound when you slide the fork into it for Gods sake, how I can possibly call it anything but. As a matter of fact, it is the
cake Ive ever had, and those who have tasted it seem to agree. I have text messages that prove it.
Very Chocolatey without tasting like dark chocolate.
When developing my dream chocolate cake, I wanted to be sure that it satisfies both adults and kids alike. That means it cant taste like dark chocolate, because 98.7% of children believe that dark chocolate comes from the devil. Yet, it cant be lacking in the chocolatiness department either, because what chocolate lover would want that? Theres a very thin line between dark chocolate and serious chocolate flavor and more often they not, they tend to overlap. This cake however, manages to embody just the right balance that guarantees a serious chocolate punch without the bitterness associated with dark chocolate.
As a person with a hankering sweet tooth, you might find it surprising that I cannot tolerate overly sweet frostings. So I made it made my mission, to keep the sweetness level under control, even if the sugar amount in the ingreditent list suggests otherwise. So
pleasantly sweet, obviously..its cake, but just perfectly so.
This is one tall cake; 6 inches to be exact! So no matter how thinly you try to slice the cake, the portion will still end up pretty big. With that in mind, I wanted to be sure that its not too rich, that one bite will put you in a food coma, yet not too light, that it feels too lean. And its just that! That rightful marriage between rich and light. Light enough that youll be able to finish your slice and still have some room for air, yet rich enough, to taste like a guilty pleasure.
Lets take a better look at what makes this cake so divine.
First of, we have 4 layers offluffy chocolate cakewith the softest, most tender crumb. The cake use a trio of tenderizers that ensures a moist texture; oil, sour cream and water. Im usually a huge proponent for cakes that use butter for its fat, because cmon its BUTTER, but theres no denying that oil makes for the moistest cakes. And while if Im going to eat a plain chocolate cake, Id still prefer it to be butter based for the rich flavor it imparts, the oil based cake just works perfectly here because all the butter in the fillings make up for the lost richness in the cake. Its a real winner and my new go-to oil-based chocolate cake recipe.
Next we have aSimple Syrup Soak. I promise, theres something in the cup.
Each layer of cake gets brushed with that liquid magic for another dimension of moisture. Its not that the cake needs it, as its pretty moist on its own, but it gives it that melt in the mouth quality that makes this cake so special.
Next comes a filling of silkyChocolate Pastry Cream, or custard if you will. This is the light element of the cake. Its barely sweet, light in texture and flavor, and tastes more of milk chocolate. When you taste it on its own, youll have doubts at how a filling this light in chocolate flavor can make a chocolate cake taste so chocolatey. The answer is because its balanced out with this:
This one is everything the pastry cream filling is not. Rich, super chocolatey, and very thick. The texture is smooth and velvety like chocolate ganache but the taste is exactly like hot fudge sauce. Ive always wondered if hot fudge sauce could transform into a spreadable frosting, and the answer came to me in the form of this gloriousness.
Together, the fluffy cake, the shower of syrup, the lightness of the pastry cream and richness of fudgy frosting, make up for one irresistible cake. Now lets take a look at how it all comes together in true Cleobuttera fashion. I hope youve missed the bajillion photos per post, because I cant go less even if I tried. And I tried. And tried. But just keep failing at making short and sweet posts. Oh wellthis cake needs quite a bit of explanation anyways.
Lets me start by getting this out of the way so I dont get comments complaining that the cake is a ton of work and that I didnt warn you, because it is. This cake IS a project, will dirty many dishes, and if you dont space your work well, then youll be standing in the kitchen all day. While difficulty is a relative thing, Id say that this cake is not difficult but requires a fair amount of baking experience. It is a highly involved cake, but honestly, the results are well worth it. You just need to really really love whoever youre making it for. I hope I havent scared you 😬
For what its worth, the cake part is dead simple. It comes together in one bowl (just be sure its an extra large bowl, because it makes A LOT of batter). You dump everything in one go then mix and youre done.
After that, youre gonna need to divide the batter equally over 4 pans. Ive found the best way to do that is to weigh the batter and divide that number by 4. Then all you do is pour that amount in each of the pans.
Also if dont have 4 pans of the same size(I only have 2), you can just bake in batches. I bake 2 pans by 2 pans. You can get more information regarding that in the notes section of the recipe.
Dont be alarmed when you see that the cakes are not very high. Theyre supposed to be 3cm tall. After the cakes have nicely cooled (I actually like to pop them in the freezer to firm up a bit), slice away any domes that may have developed on top of the cake. They make for a great kitchen reward; a pat on the back for making it this far. You can now slice each cake into 3 thin (1 cm) layers. You wanna do that very carefully, so as to try and get them of even thickness as much as possible. A cake leveler like this one, makes the process much easier.
Youll then line a cake ring or the ring of springform pan with a cake board, and line the inside with a strip of acetate or parchment paper. This will later help release the finished cake from the pan easily. The rings purpose is sturdy construction; I learned that trick from thisvideo. If youre confident in your cake building skills, you can do without it, but I like to err on the side of caution.
Place the first cake layer in there
Give it a light soak of syrup
Followed by a thin layer of chocolate pastry cream
More cake, then soak (not pictured). Note that due to the fragile nature of the cake layers, its advised to use a round flat surface to transfer them into the ring. I use a cake lifter but a cake board does the job just as well.
After that, comes a healthy slathering of the fudgy frosting.
Youre gonna keep repeating this layering process over and over until you end up with 2 separate cakes, each one comprised of 6 layers of cake and 6 layers of filling. Now choose the prettier one and play around with the last layer of frosting, because thats gonna be the top that crowns your final cake. Now off to the freezer they go, to set everything in place.
When the cakes are nice and firm, youll get them out of the freezer, and stack the cake with the decorative swirls, on top of the smoothly frosted one. Carefully peel off the acetate.
Take a moment to appreciate the different shades of chocolate, and contemplate whether you should leave it aux naturel like this and rock that trendy naked cake look, or
Then comes another big decision that youll have to makeshall you leave it like that, embrace its natural ombre/watercolor effect and maybe add a chocolate drip on top, or cover up the sides to add an element of surprise and make people wonder whats inside?
Cover it up it is! I opted forthese chocolate flakes, aka French chocolate sprinkles that I love so much and had previously used on top ofthis cupcakeand on the sides ofthese cupcakes.
And there it is! My favorite chocolate on chocolate on chocolate cake!
And make one chocolate cake lover, very very happy.
Exceptthat it actually feeds an army of chocolate cake lovers. Enlist me!
I hope you give this cake a try at least once, and not get intimidated by its several components and my long long instructions.
Until next time my dear friendssee you in 12 months!
All joking asideI promise to not disappear that long again. As Ive opened up inthispost, last year wasnt all rainbows and cupcakes, but a lot of great things came out of it, including my deep appreciation to you, my family, my health and my life. Im grateful for the opportunity to be able to come back here again, talk food with you and find you still eager to listen. You guys are the best for hanging in there and not giving up on me. And for that, I owe you a BIG thanks and a virtual hug.
As much as Im excited to be back to blogging, Im equally keen at doing it in a pace that will not take over my life the way it did before. With that said, I hope you continue to enjoy my future recipe posts in a frequency that can be best described as relaxed. I also hope that you stay as understanding as youve always been, if I go a little longer than expected without posting something new. As for me, I promise to make my sparingly spaced posts so special that it be will worth the wait, and give you only tried and true, obsessively tested recipes you could trust.
While not difficult to make, this is a multi-step, highly involved cake that requires planning ahead. Please read through the instructions and the notes in the bottom of the recipe before starting. Also check outthis videoto get a clearer vision of the assembly process before you begin. This is a HUGE cake that will feed a large crowd; to scale it down, please refer the notes in the bottom.
One (9-inch wide, 6-inch long) Mega 12 Layer Cake
4 cups (500 grams) All-purpose flour
4 cups (800 grams) granulated sugar
2 cups (170 grams) unsweetened cocoa powder
2 cups (452 grams) sour cream or Greek yogurt,
cup plus 3 tablespoons (137 grams) granulated sugar,
cup (57 grams) cold unsalted butter,
4 ounces/ 114 grams finely chopped bittersweet chocolate
(I used 66% dark chocolate callets)
1 teaspoon pure vanilla extract or 2 teaspoons imitation vanilla flavoring
12 ounces/ 354 grams bittersweet or semisweet chocolate or a combination of both
(I used bittersweet, semisweet)
1 cups heavy whipping cream
1 cups (250 grams) granulated sugar
cup plus 2 tablespoons (142 grams) unsalted butter,
Chocolate sprinkles, colored sprinkles, chocolate chips or chocolate curls/shavings (I used thesechocolate flakes)
(Can be prepared several days in advance)
Adjust oven rack to middle position and preheat the oven to 350F/180C. Spray (or grease) four 9-inch round cake pans with non-stick cooking spray, line with parchment paper, then spray (or grease and flour) the parchment and pans. If you dont have four 9-inch pans, use whatever amount you have and bake in intervals. You just want to end up with four equal cake layers. (*For more details on that, please refer to the NOTES below)
In a very large bowl, sift together the flour, sugar, cocoa powder. baking soda, baking powder and salt.
To the dry ingredients, add the eggs, sour cream, water, oil, vanilla extract and mix together using an electric mixer until well combined and smooth. Batter will be very thin.
Divide the batter evenly among the prepared pans. A great way to do that, is to weigh the batter, and divide that number by the amount of pans used, which is 4 in the case of this recipe. Using a scale to measure, fill each pan with the resulted amount.
Bake until the center of the cakes spring back when pressed lightly with your fingers and a toothpick inserted into the center of each cake comes out clean (a few moist crumbs attached are ok); about 25 minutes.
Let the cakes cool in the pans on wire rack for 15 minutes. Invert cakes onto a cake board or plate and peel off parchment; reinvert cakes onto the wire rack. Allow to cool until slightly warm or at room temperature, then wrap in a double layer of plastic wrap and keep in the freezer until cold and firm but not frozen. This step is optional, but it makes the process of slicing the cakes into thin layers, cleaner and easier. Alternatively, you could keep the cakes in the freezer for up to several days.
(*For make ahead details, please refer to the NOTES below)
Meanwhile, make the other cake components.
(can be prepared up to a week in advance)
Combine the sugar and water in a small saucepan and heat over medium heat, stirring occasionally, until the sugar has dissolved; set aside to cool completely before using.
(Can be prepared up to 2 days in advance)
Heat the milk, heavy whipping cream, cup (100 grams) of the sugar, and the salt in a medium heavy-bottomed saucepan over medium heat until simmering, stirring occasionally to dissolve the sugar.
Meanwhile, whisk the egg yolks and the remaining 3 tablespoons (37 grams) of sugar in a medium bowl, until the sugar has begun to dissolve and the mixture is creamy, about 15 seconds.
(IMPORTANT: Dont whisk the egg yolks and sugar together until the milk mixture is already heating, because if left together for too long, the sugar will start to cook the yolks)
. Whisk in the cornstarch vigorously until the mixture is pale yellow and thick, about 30 seconds.
When the milk mixture reaches a full simmer, gradually whisk the simmering milk into the yolk mixture to temper. Dont do it too fast, or youll risk cooking the eggs. Return the mixture to the saucepan, scraping the bowl with a rubber spatula. Return to a simmer over medium heat, whisking constantly, until a few bubbles burst on the surface and the mixture is thickened and glossy, about 30 seconds. Be careful not to cook the mixture beyond the point of a few bubbles or the mixture can start to curdle and the yolks may scramble…not fun! Turn off the heat, whisk in the butter, chocolate, and vanilla.
Strain the pastry cream through a fine-mesh sieve set over a medium bowl. Press plastic wrap directly on the surface to prevent a skin from forming and refrigerate until cold and set, at least 3 hours or up to 2 days.
Place the chocolate in a large bowl. Heat cream, sugar, and salt in saucepan over medium-low heat, stirring occasionally, until sugar dissolves and mixture begins to simmer. It is very important to make sure that the sugar has dissolved completely, so you dont end up with a gritty frosting.
Pour hot cream mixture over chocolate and whisk until smooth. Whisk in the butter until glossy. Cover and refrigerate until icing is firm but still spreadable, about 1 hour.
Since this mega cake is a 6-inch tall beast, it is best to treat it as 2 separate cakes that well later fuse into one; it will make for a sturdier construction that way. Check outthis videoto get the picture. Start by lining the bottom of a 9-inch cake ring or the ring of springform pan with a 9-inch round cake board. Line the inside of the ring with a strip of acetate or parchment paper. This will later help release the finished cake from the ring easily.
If your cakes are domed, level them off by slicing away a thin layer from the top; you need the cakes to be as flat as possible. Using a serrated knife or cake leveler, as careful as you can, slice each of the 4 cakes into 3 layers of equal thickness, about 1cm each. You should end up with a total of 12 layers.
Using a round cake board or cake lifter, transfer the bottom layer of one of the cakes inside the ring. Using a pastry brush, lightly brush the surface of the cake layer with the Simple Syrup Soak.
Using an offset spatula or back of a spoon, spread a little over cup of the Chocolate Pastry Cream evenly over the cake layer, all the way to the sides of the ring.
Top with a second cake layer, then brush with the Simple Syrup Soak. Spread a little over cup of the Fudgy Frosting evenly over the cake layer, all the way to the sides of the ring. Using up 2 of the 4 cakes, repeat, alternating layers of cake, Chocolate Pastry Cream, cake, Fudgy Frosting, brushing each cake layer with the Simple Syrup Soak. End with a smooth layer of Fudgy Frosting. You should now have 6 layers of cake and 6 layers of filling. Cover the cake loosely with plastic wrap and place in the freezer to set.
Using another 9-inch cake ring or the ring of springform pan, repeat Steps 3 through 5, using the remaining 2 cakes and the remaining Chocolate Pastry Cream, Fudgy Frosting and Simple Syrup Soak. Top the final layer of cake, decoratively, with the last bit of Fudgy Frosting creating swoops and swirls, as this will be the top layer of the final cake. If you dont have an extra 9-inch cake ring
carefully slide the first cake out of the ring, keeping the acetate intact, cover, freeze, and reuse the same ring to assemble the other cake.
Freeze the 2 assembled base cakes until very firm and sturdy; 1 to 2 hours. You could even freeze it for several days (*For make ahead details, please refer to the NOTES below).
Pop the cakes out of the cake ring(s). Gently peel off the acetate of the cake you plan to place on the bottom. Make sure the Fudgy Frosting topping on that cake, is soft enough to adhere to the top cake when placed on it. If its too cold and dry, warm through using a kitchen torch.
Top the bottom base cake with the top base cake
(the one with the pretty swirls on top)
. Dont forget to remove its cake board before you do! Peel off its acetate. Use an offset spatula to smooth out the sides of the cakes, fusing them together as you go, and scrapping off any excess and filling the gaps with it.
Place the final cake on a rimmed baking sheet to catch any decoration fall outs. Cover the sides of the cake with the garnish of your choice. I used theseChocolate Flakes.
Place the cake under a cake dome and allow to come to room temperature before serving. Timing will vary depending on how long the cake was left in the freezer. Serve at room temperature, or slightly warmed in the microwave. Leftovers will keep well chilled in the fridge in an airtight container.
* It is highly recommended that you make the cake at least 1 day before serving, as it is time consuming and requires several chilling times.
* The finished cake will keep well in the fridge for 1 day under a cake dome, but leftovers will taste great for up to 3 days given that theyre stored in an airtight container in the fridge. Bring to room temperature before serving or warm individual slices slightly in the microwave.
* The cake layers can be made up to several days in advance. Wrap in a double layer of plastic wrap, place in a freezer zipper-lock bag and store in the freezer until needed. Thaw slightly before slicing into thin layers.
* The filled and frosted cake bases, can also be made several days in advance and stored in the freezer until needed. Be sure to wrap them well in a double layer of plastic wrap and place in a freezer zipper-lock bag. Note that if you freeze them for that long, condensation many occur on the surface of the cake. Allow the condensation to take its time to evaporate, then dap whatever may be leftover with a smooth paper napkin.
* Dont need a cake that feeds an army? Cut the recipe in half and bake in four 6-inch pans. Alternatively, make a shorter (6-layer cake) version of the cake in the same 9-inch pans. Same delish taste. less work!
* 8-inch cake pans may also be used. It will actually slice easier because the layers are thicker, but know that your finished cake will be extra tall which may compromise stability.
* Dont have FOUR 9-inch pans, no problem! I only have TWO and make this work! To do that, weigh your batter, divide that number by 4 (which is the number of pans/layers we need). Place your first pan on the scale and fill up with batter using the amount you got on the calculator as a guide. Repeat with your second pan. Bake those 2 pans, cool slightly, invert cakes, wash and dry pans, grease and line with new parchment rounds, fill up with the remaining batter using the scale, then off to the oven they go.
* If available where you live, 3 cups of half-and-half may be used instead of the heavy cream/ milk combination in the Chocolate Pastry Cream.
* Dont throw away those egg whites! Egg whites freeze beautifully and will come in handy in recipes that require egg whites only likethisandthis.

Welcome back, dear friend! The cake looks phenomenal and yes, well worth the wait. I appreciate all of the effort you put into your posts and the obsessive testing component that goes along with it. As I write this, Ive just taken the 8th trial of a cake out of the oven! At this rate, it might get pushed off for yet another year as the season for it passes by
🙁 Your beautiful photography style is always a treat for hungry eyes. I hope you enjoy your return and keep the stress level low and in control. I like the phrase, relaxed pace. I know whatever pace they come in, your posts will always be worth the wait.
Ramona your sweet and kind comments never fail to put a huge smile on my face. Thank you for always staying in touch, your continuous support and being my favorite blogging buddy to vent with.
I know what youre going throughbatches after batches of less than perfect cakes are not fun! Ive been postponing red velvet, yellow cakes and basbousa (Egyptian semolina cake) for these same reasons. Its really your dedicated testing that makes your blog, one of the most reliable baking sources out there, so keep up the obsessiveness. Wishing you best of luck with your beautiful blog and life.
One of my favourite cakes !! Only had it once at a bakery in the US but never thought I will be able to make one !! Thank you for the recipe. I am sure it will taste a million times better than a store bought one . So happy you are back . Good luck ❤️
Thank you dearest Mona! Its so cool that you had a chance to try the real deal. Do you remember the name of the bakery? I had to imagine the flavor and textures to be able to come up with a homemade version but Im s
