I made a neapolitan cake for my bff's bday bbq this past Sunday. It was a gorgeous day out in Tomales Bay and a perfect way to spend quality time with her, our friends, and her immediate family. I was brainstorming what kind of cake I should make for her birthday and decided on a neapolitan cake. I didn't realize what I had committed myself to when I started making three different kinds of cakes and two different frostings/fillings. LOL. It was well worth it tho. The cake was a huge hit despite the melted frosting. The cakes were moist and not too sweet. Neither flavors overpowered the other and the fresh strawberry filling complimented the cakes perfectly. Next time, I might just use a simple whipped cream frosting instead of the vanilla buttercream.
Neapolitan Cake
adapted from Annies Eats and Baking Bites
Ingredients: For the chocolate cake:
¾ cup plus 2 tbsp. all-purpose flour 6 tbsp. dark cocoa powder 1 tsp. baking soda ½ tsp. baking powder ½ tsp. salt 1 cup sugar ¼ cup vegetable or canola oil 1 large egg ½ cup black coffee (
I made a quick trip to Starbucks and used their drip coffee of the day) ½ cup buttermilk 1½ tsp. vanilla extract
For the white cake:
1 cup milk, room temperature
6 egg whites ( I used 12 tbsp of pure eggwhites in a carton)
1 tsp almond extract
1 tsp vanilla extract
2 1/4 cups cake flour
1 3/4 cups sugar
4 tsp baking powder
1 tsp salt
3/4 cup butter (6 oz), softened ( I only used 4 oz)
For the strawberry cake:
1¼ cups plus 2 tbsp. all-purpose flour
1¼ tsp. baking powder
¼ tsp. salt
1 cup sugar
1½ oz. strawberry gelatin
8 tbsp. unsalted butter, at room temperature
2 large eggs
½ cup milk
1½ tsp. vanilla extract
¼ cup sweetened strawberry puree*
Strawberry Filling:
1½ cups fresh strawberries (8 oz.), rinsed, hulled and coarsely chopped*
4 large egg whites
1¼ cups sugar
3 sticks (1½ cups) unsalted butter, at room temperature
*To make the strawberry puree, process partially thawed frozen strawberries with a bit of sugar in a blender or food processor until smooth. If using sweetened frozen strawberries, no additional sugar is necessary.
Vanilla Buttercream
Ingredients:
20 tbsp. (2 ½ sticks) unsalted butter, softened
2 ½ cups confectioners’ sugar, sifted
1/8 tsp. salt
2 tsp. vanilla extract
2 tbsp. heavy cream
Directions:
In a stand mixer fitted with the whisk attachment, beat butter at medium-high speed until smooth, about 20 seconds. Add confectioners’ sugar and salt; beat at medium-low speed until most of the sugar is moistened, about 45 seconds. Scrape down the bowl and beat at medium speed until mixture is fully combined, about 15 seconds. Scrape bowl, add vanilla and heavy cream, and beat at medium speed until incorporated, about 10 seconds. Then increase the speed to medium-high and beat until light and fluffy, about 4 minutes, scraping down bowl once or twice.
To make the chocolate cake, butter and flour the edges of a 9-inch round pan, shaking out the excess flour. Line the bottom with a round of parchment. In a small bowl, combine the flour, cocoa powder, baking soda, baking powder and salt; whisk to blend and set aside. In the bowl of an electric mixer, combine the sugar, vegetable oil and egg. Beat on medium speed until smooth, about 1-2 minutes. With the mixer on low speed, blend in half of the dry ingredients, beating just until incorporated. Blend in the coffee, buttermilk and vanilla just until smooth. Beat in the remaining dry ingredients, mixing just until incorporated.
Preheat the oven to 350˚ F. Pour the batter into the prepared pan and bake, rotating halfway through, until a toothpick inserted in the center comes out clean, about 35 minutes. Transfer to a wire rack and let cool in the pan for 20 minutes. Run a knife around the edges, then turn the cake out onto the rack and let cool completely.
Grease a 9 inch cake pan with vegetable shortening, line the bottom with parchment paper, grease the parchment paper and flour the pan.
To make the white cake, combine milk, eggs whites and extracts in a small bowl with a fork. Set aside. Combine flour, sugar, baking powder and salt in an electric mixer and mix at slow speed with a paddle attachment. Add butter. Continue beating at slow speed until mixture looks like wet sand (If you’re doing this by hand, sift the dry ingredients together and rub in butter). Add all but 1/2 cup of milk mixture and beat at medium speed for 1 1/2 minutes. Add remaining milk mixture and beat for an additional 30 seconds, scraping the sides of the bowl if necessary. Do not overmix.
To make the strawberry cake, butter and flour the edges of a 9-inch round pan, shaking out the excess flour. Line the bottom with a round of parchment. In a small bowl, combine the flour, baking powder and salt; whisk to blend and set aside. Combine the sugar, strawberry gelatin and butter in the bowl of an electric mixer. Beat on medium-high speed until light and fluffy, about 2-3 minutes. Beat the eggs into the sugar mixture one at a time, mixing well after each addition. With the mixer on low speed, add half of the dry ingredients to the batter and mix just until incorporated. Blend in the milk and vanilla extract. Add in the remaining dry ingredients, mixing just until incorporated. Blend in the strawberry puree.
Preheat the oven to 350˚ F. Pour the batter into the prepared pan and bake, rotating halfway through, until a toothpick inserted in the center comes out clean, about 35 minutes. Transfer to a wire rack and let cool in the pan for 20 minutes. Run a knife around the edges, then turn the cake out onto the rack and let cool completely.
To make the frosting, place the strawberries in a food processor or blender. Puree until completely smooth. Combine the egg whites and sugar in a heatproof bowl set over a pot of simmering water. Heat, whisking frequently, until the mixture reaches 160° F and the sugar has dissolved.
Transfer the mixture to the bowl of a stand mixer** fitted with the whisk attachment. Beat on medium-high speed until stiff peaks form and the mixture has cooled to room temperature, about 8 minutes. (The bowl should be cool to the touch.)
Reduce the speed to medium and add the butter, 2 tablespoons at a time, adding more once each addition has been incorporated. If the frosting looks soupy or curdled, continue to beat on medium-high speed until thick and smooth again, about 3-5 minutes more (or longer – don’t worry, it will come together!) Blend in the strawberry puree until smooth and completely incorporated, scraping down the sides of the bowl as needed.
To assemble the cake, torte each of the cake layers horizontally into two thin halves. Place one of the chocolate layers on a cake board or cake platter. Top with a very thin layer of the vanilla buttercream or strawberry jam. Place a layer of the strawberry cake on top. Again, cover with a thin layer of vanilla buttercream or strawberry jam. Top with a layer of the white cake. Cover with a thin layer of the vanilla buttercream or strawberry jam. Repeat the process with the remaining layers of chocolate and strawberry cake. (For a taller cake, you can use the remaining layer of white cake. Otherwise, you can wrap tightly and save for later use or discard.) Frost the top and sides of the cake with the vanilla buttercream. Transfer remaining buttercream to a pastry bag fitted with a decorative tip for detailing as desired.
