Method
- Preheat your oven to 350°F (175°C). Butter and line three 8-inch round cake pans with parchment paper.
- In a bowl, whisk together the all-purpose flour, baking powder, and salt for the vanilla cake layers.
- In another bowl, using a mixer, cream the softened butter and granulated sugar until light and fluffy for the vanilla cake mixture.
- Beat in the eggs one at a time, mixing well after each addition, then mix in the vanilla extract.
- Alternately add the flour mixture and whole milk to the creamed butter and sugar, beginning and ending with the flour until just combined.
- Pour half of the vanilla cake batter into one prepared pan and set the rest aside.
- In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt for the chocolate cake layer.
- In a mixer bowl, cream together the softened butter and granulated sugar for the chocolate batter.
- Beat in the eggs one at a time, then add the vanilla extract.
- Alternately add the dry ingredients and whole milk to the chocolate mixture until just combined.
- Pour the entire chocolate batter into the second prepared pan.
- Take the reserved vanilla batter and add dollops into the third pan, followed by dollops of the reserved chocolate batter. Swirl with a knife to create a marble effect.
- Bake all pans for about 28-32 minutes, or until a toothpick inserted in the center comes out clean. Cool cakes in pans for 10 minutes, then carefully turn onto a wire rack to cool completely.
- Beat the softened butter for the buttercream frosting until creamy, then gradually add confectioners’ sugar, beating well.
- Beat in vanilla extract, a pinch of salt, and milk until the frosting is fluffy.
- Level the cooled cake layers using a serrated knife.
- Using round cookie cutters (6-inch and 3-inch), cut concentric rings in each cake layer. Carefully exchange inner and outer rings to alternate chocolate and vanilla cakes in each layer.
- Spread a thin layer of buttercream between the rings to hold them, then stack the cake layers with frosting between them.
- Apply a thin ‘crumb coat’ of frosting around the entire cake and chill for 20 minutes.
- Finish with a smooth, even layer of buttercream on top and sides, and decorate as desired.
Notes
To enhance presentation, decorate with chocolate shavings, sprinkles, or piped frosting.
Cake layers can be made a day ahead and wrapped tightly before assembling.
For deeper flavors, add a touch of espresso to the chocolate batter.
