Equipment

  • Bundt pan
  • 9-inch Round Cake Pan
  • Medium-sized bowl
  • Large mixing bowl
  • Electric mixer
  • Knife or Skewer
  • Wire rack

Ingredients
  

  • 2 cups all-purpose flour
  • 1.5 tsp baking powder
  • 0.5 tsp baking soda
  • 0.5 tsp salt
  • 0.5 cup unsalted butter softened
  • 1.5 cups granulated sugar
  • 3 large eggs
  • 1 tsp vanilla extract
  • 1 cup buttermilk
  • 0.33 cup cocoa powder
  • black food coloring gel food coloring recommended
  • orange food coloring gel food coloring recommended
  • 0.5 cup semi-sweet chocolate chips optional

Instructions
 

  • Step 1: Preheat your oven to 350°F (175°C). Grease and flour a bundt pan or a 9-inch round cake pan thoroughly.
  • Step 2: In a medium-sized bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until nicely combined. Set aside.
  • Step 3: In a large mixing bowl, cream together the softened unsalted butter and granulated sugar with an electric mixer until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  • Step 4: Alternately add the dry ingredients mixture and the buttermilk into the butter-sugar-egg batter. Start with about a third of the dry, mix gently, then half the buttermilk, mix, another third of the dry, mix, the remaining buttermilk, mix, and finally the last of the dry ingredients. Mix just until everything is smooth and combined, being careful not to overmix.
  • Step 5: Divide the batter evenly into three separate bowls. Leave one bowl plain (vanilla). To the second bowl, add the cocoa powder and black food coloring and mix until deep black. To the third bowl, add orange food coloring and mix until vibrant orange.
  • Step 6: Take spoonfuls of each colored batter and dollop them randomly into your prepared cake pan, alternating colors. Once all the batter is in, gently swirl through the batters once or twice with a knife or skewer to create a marbled effect, without fully mixing the colors.
  • Step 7: (Optional) Sprinkle the semi-sweet chocolate chips evenly over the top of the cake batter.
  • Step 8: Bake for about 40–45 minutes, or until a toothpick inserted into the center comes out clean.
  • Step 9: Let the cake cool in the pan for about 15 minutes before gently transferring it to a wire rack to cool completely.

Notes

Substitutions & Additions: In a pinch, use a vanilla or yellow cake mix as your base, preparing it according to package directions before dividing and coloring. Experiment with different food colors like purple and green, or red and black for various themed parties. Swap vanilla extract for almond extract, or add a touch of orange zest to the orange batter. This cake is delicious on its own but can be enhanced with cream cheese frosting, vanilla buttercream, or a drizzle of melted white chocolate. Decorate with Halloween sprinkles, candy corn, gummy worms, or edible googly eyes before serving.
Tips for Success: Do not overmix the batter when combining wet and dry ingredients, as this can lead to a tough cake. Ensure your butter is truly softened (not melted) for a light and airy batter. Use gel food coloring for vibrant hues without thinning the batter. When marbling, less is more; a few gentle swirls are sufficient to create the effect. Ensure eggs and buttermilk are at room temperature for a smoother emulsion and consistent texture. To save time, whisk dry ingredients ahead of time or let butter and eggs come to room temperature.
Storage: Store cooled, unfrosted cake in an airtight container at room temperature for up to 2-3 days. If frosted with a dairy-based frosting, store in an airtight container in the refrigerator for up to 5 days, allowing it to come to room temperature for 30 minutes before serving. Unfrosted slices or whole cakes can be frozen for up to 3 months when tightly wrapped in plastic wrap and aluminum foil; thaw overnight in the refrigerator.
