Marble Cake

Rich and delicious. Very 'showy' cake!

Ingredients

  • 4 oz. Chocolate Chips
  • 1/2 cup Butter, softened
  • 1/2 cup Vegetable oil
  • 1 3/4 cup White, granulated sugar
  • 4 lge. Eggs, room temperature
  • 2 tsp. Vanilla extract
  • 3 cups Flour
  • 1 Tbsp. Baking powder
  • 3/4 tsp. Salt
  • 1 1/4 cup Buttermilk, room temperature

For the Buttercream Frosting

  • 1 cup Butter, softened
  • 2 cups Confectioners sugar
  • 1/2 tsp. Vanilla extract
  • 1/2 tsp. Salt
  • 2 Tbsp. Heavy cream

Instructions

For the Cake:

  • Preheat oven to 350 degrees. Generously grease and flour two 8" cake pans. Set aside.
  • Place the chocolate chips in a microwavable bowl and microwave for 30 seconds. Stir well, and then return to the microwave and heat in 15 second increments, stirring well in between until chocolate is completely melted and smooth. Set aside.
  • Using an electric or stand mixer, cream together butter, oil and sugar until light and fluffy.
  • Add eggs, one at a time, beating after each addition. Stir in vanilla extract.
  • In a separate bowl, whisk together 3 cups flour, 1 Tbsp. baking powder and 3/4 tsp. salt.
  • Using a spatula and gently hand-mixing, alternate adding flour mixture and buttermilk to the butter/oil batter, starting and ending with the flour mixture and mixing until just combined after each addition. Do not overmix!
  • Pour 1/2 of the batter into a separate bowl and add the melted chocolate chips. Stir until completely combined and batter is evenly chocolate.
  • Alternate adding vanilla and chocolate batter to each pan, evenly distributing batter into each pan. Use a knife to swirl for the marbled appearance.
  • Bake at 350 degrees for 30 minutes. Do not overbake.
  • Allow cakes to cool in the pan for 10 minutes before turning out on a rack to cool completely before frosting.

For the Frosting:

  • Using an electric mixer, cream the softened butter until light and fluffy. Slowly add the confectioners sugar, scraping down the sides of the bowl as needed. Beat in 2 Tbsp. heavy cream.
  • Sprinkle in salt and vanilla extract. Beat until well combined.
  • The chocolate ganache decoration is optional. See ganache recipe above.
