Ingredients

  • 2 tablespoons butter, or as needed
  • 2 1/4 cups cake flour
  • 1 cup white sugar
  • 2 teaspoons baking powder
  • 1 cup buttermilk, at room temperature
  • 3/4 cup butter, at room temperature
  • 3 eggs, at room temperature
  • 1 teaspoon vanilla extract
  • 2 teaspoons orange food coloring powder
  • 1/2 cup cocoa powder
  • 1 teaspoon black food coloring powder

Method

  • Preheat the oven to 350 degrees F (175 degrees C). Grease a fluted tube pan (such as Bundt(R)) with 2 tablespoons butter.
  • Mix flour, sugar, and baking powder in a large bowl. Beat in buttermilk using an electric mixer. Add 3/4 cup butter and beat until fully incorporated. Mix in eggs and vanilla extract until smooth.
  • Pour 1/3 of the batter into a small bowl; mix in orange food coloring. Add cocoa powder and black food coloring to the large bowl. Mix well, scraping down the sides.
  • Pour black batter into the cake pan. Pour orange batter on top. Rap pan against the counter to release any air bubbles.
  • Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 50 minutes. Cool for 15 minutes before removing from the pan.
