Chocolate Marble Cake

A classic marble cake that is as delicious as it is easy to make. This is a recipe from Carol Bloom's The Essential Baker with a minor tweak or two, and the cake is one you can serve for any occasion.

Ingredients

White Cake Batter

  • 4 oz unsalted butter, softened
  • 1 cup sugar
  • 2 extra large eggs, room temp
  • ½ cup milk
  • 1 tsp pure vanilla extract
  • 1 ⅓ cups cake flour
  • 1 ½ tsp baking powder
  • ¼ tsp baking soda
  • ¼ tsp salt

Chocolate Cake Batter

  • 4 oz unsalted butter, softened
  • 1 cup sugar
  • 2 extra large eggs, room temp
  • ½ cup milk
  • 1 tsp pure vanilla extract
  • 1 cup cake flour
  • cup cocoa powder
  • 1 ¼ tsp baking powder
  • ¼ tsp baking soda
  • ¼ tsp salt

Instructions

Mix each cake in the same way

  • Preheat oven to 350°F. Line the cake pans with butter and parchment circles. 
  • Cream the butter or 2 minutes in a stand mixer fitted with the paddle attachment. Add the sugar and continue creaming until light and fluffy, scraping down bowl as needed, about 2 more minutes. Lower speed and add each egg, one at a time, blend until incorporated and scrape bowl as needed.
  • Mix together the milk and vanilla in a measuring cup.
  • In a bowl, whisk together the dry ingredients. Add this to the butter mixture, alternating with the milk mixture. Start and end with the dry ingredients. Scrape bowl as needed.
  • Pour the two batters into the pans and swirl together to make the marbling. Bake for about 20 to 30 minutes, depending on the size of the pan
  • Spread mocha buttercream on cake. I used a cake comb to create the swirl effect.

Notes

*I can't share the recipe for Sarah's chocolate frosting (which you see in the photos above) because it's from her cookbook, but the mocha buttercream I link above is a good alternative.
