Vanilla Cake with Tiramisu Buttercream and Ganache Filling

Vanilla Cake with Tiramisu Buttercream and Chocolate Ganache Filling

Already getting a good start tackling my baking resolutions (and it’s not even the new year)… I’ve moved from macarons to fondant. I stumbled upon a fondant cake decorating class in our area, and immediately jumped at the opportunity to get my hands dirty. My first attempt (solo – stupid!) failed so miserably, I realized that just watching people decorating cakes on TV was not a suitable learning tool.

The supply list for this class included a cake. Which makes sense, I guess, it’d be pretty ridiculous if they provided cake for everyone. So Friday night before the class I got to work baking a cake.

I’m sure if this was Taylor taking the class (which, that alone is very unlikely anyway), he would have just thrown together a box mix cake. It’s just practicing after all, why spend the time baking a real cake from scratch. But you know me, a box mix just will not do. I won’t even settle for a homemade cake and quick plain buttercream. Nope. I spent as much time thinking about the inside of the cake as I did decorating the outside.

The result was a delicious yellow cake, filled with a coffee-flavored swiss meringue buttercream and a layer of chocolate ganache. Tasty! The end result reminded me a lot of Tiramisu – the creamy meringue buttercream spiked with coffee, the rich vanilla buttermilk cake… with a chocolaty twist.

Fondant Ribbon Bow

The actual decorating was quite a success as well. Actually seeing a cake covered in fondant step by step makes a huge difference. And I could barely believe how easy the bow was. Aside from a few small blips and tears, I think it looks pretty darned nice!

What I need to find are some miniature cake pans. Like, figure out what exactly half of an 8 inch 3-layer-cake recipe would yield (5″? 6″? Math geniuses, help me out!) With a smaller cake I could bake them more often and wouldn’t feel so guilty about just the two of us eating the entire thing. Practice my decorating skills without needing a special occasion as an excuse!

Vanilla Cake with Tiramisu Buttercream and Chocolate Ganache Filling

Though, as pretty as the outside looks, I do have to say that the inside just might be the prettiest part. :)

Vanilla Cake with Tiramisu Buttercream and Bittersweet Ganache Filling

Makes one three-layer 9-inch round cake, or a three-layer 8-inch round cake and 6 cupcakes.
Cake recipe adapted from Sky High: Irresistible Triple-Layer Cakes. Buttercream adapted from Martha Stewart.


3 3/4 cups cake flour
2 1/2 cups sugar
1 tablespoon plus 2 3/4 teaspoons baking powder
1/2 teaspoon salt
2 1/2 sticks (10 ounces) unsalted butter, at room temperature
1 1/4 cups plus 1/3 cup buttermilk
5 whole eggs
2 egg yolks
2 1/2 teaspoons vanilla extract

Buttercream: (halve this recipe if you will be covering the cake with fondant)
6 large egg whites
1 1/2 cups sugar
1 teaspoon pure vanilla extract
1 1/4 pounds (5 sticks) unsalted butter, softened
2 tablespoons warm water
1 tablespoon instant coffee

1/3 cup heavy cream
3 ounces bittersweet chocolate, chopped


Preheat the oven to 325°F. Butter three 9-inch round cake pans. Line the bottom of each pan with a round of parchment or waxed paper and butter the paper.

Combine the cake flour, sugar, baking powder, and salt in a large mixer bowl. With the mixer on low speed, blend for 30 seconds. Add the butter and 1 1/4 cup of the buttermilk. Mix on low speed briefly to blend; then raise the speed to medium and beat until light and fluffy, 2 to 3 minutes.

In a smaller bowl, whisk together the whole eggs, egg yolks, vanilla, and the remaining 1/3 cup buttermilk until well blended. Pour one-third of the egg mixture into the cake batter at a time, folding it in completely after each addition. There will be 9 cups of batter; our 3 cups batter into each pan.

Bake for 26 to 28 minutes, or until a cake tester or wooden toothpick inserted in the center comes out clean.

Turn the layers out onto wire racks by placing a rack on top of a pan, inverting it, and lifting off the pan. Peel off the paper liners and let cool completely. When the layers have cooled, place a cardboard cake board on top of a layer, invert again, and lift off the rack. To make the layers easier to handle, wrap them on their boards completely in plastic, so they don’t dry out, and refrigerate them.

To make buttercream, combine the sugar and egg whites in a large heatproof bowl over a saucepan of simmering water and whisk constantly, keeping the mixture over the heat, until it feels hot to the touch, about 5 minutes. The sugar should be dissolved, and the mixture will look like marshmallow cream. Remove from heat and transfer to the bowl of a stand mixer, and whisk on high speed until mixture is completely cooled and stiff peaks form, about 6 minutes. Beat in vanilla. Add butter, 2 tablespoons at a time, on low speed, mixing well after each addition. Beat until smooth, about 3 minutes.

Stir instant coffee into warm water until dissolved. Add, 1 teaspoon at a time, to buttercream, mixing well after each addition, until you’re satisfied with the strength of the coffee flavor (I added about 1 tablespoon).

To make ganche, place chopped chocolate in a heat proof bowl. In a heavy saucepan set over medium heat, bring the heavy cream to a boil. Remove from the stove and pour over chopped chocolate. Let stand 2 minutes and then stir until fully combined. Let cool until just firm enough to spread onto cake layers.

After leveling cake layers as necessary, place one cake layer on a cake board, flat side up. Brush with sugar syrup (if desired, it will help keep the cake moist). Spread half of the ganache evenly over the top, followed by approximately 3/4 cup of the buttercream. Repeat with the second cake layer, by first brushing on some sugar syrup, followed by more ganache and buttercream. Top the cake with the third layer. Lightly crumb coat the the cake with more buttercream. At this point you can either cover the cake with fondant, or frost it with a thick layer of buttercream.

  1. Hi there,
    Planning to make this cake for a birthday. Can I freeze it after assembly so that it’s easily transported to the event?

    • Technically yes, but I personally don’t love freezing fully frosted cakes; buttercream tends to get a little sweaty when it thaws from freezing as will fondant.

    I made this cake for my mom’s birthday, since she’s a big fan of tiramisu, and it was a great hit! The whole family enjoyed it! Will definitely make it again. Thank you! 

  3. Hi there, the cake look and possibly taste wonderful. I will have a go but have a quick question first: how many tbls/tspns of baking pwder ? Did I get it wrong ?

    1 Tbls plus 2 3/4 tspns ?

  4. I have a question.  Do you add the butter in chunks until it’s a “sandy” consistency before adding the buttermilk or at the same time?  I’m used to the Reverse Creaming Method where you add butter first and then proceed.  
    Thank you for your advice!

  5. I wanted to get some clarification before making your cake.  Usually when I use the Reverse Creaming Method I add the cubed butter a little at a time into dry ingredients til it becomes a sandy texture and then add the liquid and mix for 2 minutes.  Reading your recipe it sounded like you put the butter and buttermilk in at the same time? Is that correct?  Also at the end of the recipe it states to fold in the liquid egg whites in 3 stages.  Did you mean to fold it in by hand?  Because of the slipperiness of the whites that is more difficult than adding the whites in using the Stir speed on my mixer to incorporate without knocking out any air.  I just want to make sure I am preparing this correctly.

    Thank you

  6. I need to make a two tiered cake—10″ 3 layers and a 8″ 3 layers of your Vanilla Cake with Tiramisu Buttercream and Bittersweet Ganache Filling.  For the 10″ would I need to make one and a half of the recipe to increase the 9″ to 10″ layers?  I appreciate any advice.

    Thank you

  7. Hola hize la receta ahora me gustaria saber como conservarlo?

  8. This cake is AMAZING! It turned out perfectly. I am saving this recipe to make again. Thank you for sharing this wonderful recipe.

  9. Cake does not rise very high definitely not like the picture only like an inch in height

    • Did you use the same 8-inch pan size as I did? 9 inch pans would produce thinner layers overall.
      But if the cakes themselves didn’t rise very much, I’d check the freshness of your baking powder as it sounds like it might not be active anymore?

  10. Thank you…..the butter was softened at room temperature, so the mixture must of been too warm

  11. Followed the recipe for the buttercream frosting was watery after adding first stick of butter….. I can only imagine by adding for more sticks of butter would really make it runny….had to trash frosting and use store bought frosting

  12. DELICIOUSSSSSS!!!! I just made this cake, followed the recipe as is and I have to say this is WOONDERFUULL!!!! LOVED IT not just me, family and friends too!!!!!! I’m making another one this weekend…!!! :D

  13. Hello, I tried making this cake today and Im sadly reporting that it completely flopped. :(  I followed  the instructions to the “t”  but the cake overflowed the pan and after 1 hr,  of baking it still never cooked. Reading the comments above I am thinking I used too much baking powder. I live in a high altitude area and probably had to adjust for that. Do you have any suggestions regarding high alitide adjustment for the BP? 

  14. A 6×2 inch cake pan holds 2 to 2 1/4 cups of batter. Not sure how many cups the recipe yields but I want to try it. Sounds yummy.
