  • Total Time: 2 hour 5 minutes
  • Yield: 1214 slices 1x

Ingredients

Scale
  • 2 1/4 cups all purpose flour

  • 2 1/2 tsp baking powder

  • 1/4 tsp baking soda

  • 1/2 tsp salt

  • 1/2 cup unsalted butter, room temperature

  • 1/2 cup vegetable oil

  • 1 1/2 cups sugar

  • 1 tbsp Vanilla Extract (Alcohol-Free)

  • 4 large eggs

  • 1 cup buttermilk

  • 5 oz bittersweet chocolate, chopped

  • Black gel icing color

  • Red gel icing color

  • 2 1/4 cups unsalted butter

  • 8 cups powdered sugar

  • 1 cup natural unsweetened cocoa powder

  • 2 tsp Vanilla Extract (Alcohol-Free)

  • 57 tbsp water or cream

  • 1/4 tsp salt

  • Black gel icing color

  • 4 oz red candy melts

  • 2 tbsp heavy whipping cream

  • Halloween sprinkles

Instructions

  • Preheat oven to 350°F (176°C). Grease three 8-inch pans, line with parchment, and dust edges lightly with flour.

  • Whisk flour, baking powder, baking soda, and salt together. Set aside.

  • Melt chocolate in the microwave in short bursts, stir smooth, and allow it to cool slightly.

  • Beat butter, oil, and sugar until fluffy. Add eggs one at a time, mixing well after each addition. Stir in Vanilla Extract (Alcohol-Free).

  • Alternate adding dry ingredients and buttermilk. Begin with dry ingredients and end with dry ingredients. Mix only until smooth.

  • Divide batter into three bowls. Tint one portion red, one portion black, and leave one plain.

  • Spoon alternating dollops of batter into pans. Swirl gently with a knife to create marble patterns.

  • Bake 20–25 minutes, or until a toothpick comes out clean. Cool in pans 10 minutes, then transfer to wire racks to cool fully.

  • To make frosting, beat butter until creamy. Gradually add powdered sugar. Mix in cocoa powder, salt, Vanilla Extract (Alcohol-Free), and water or cream until smooth. Tint with black gel color.

  • Level cake layers if needed. Stack each layer with frosting between. Apply a thin crumb coat and chill 20 minutes. Then frost the cake completely.

  • For the drip, melt candy melts with cream until smooth. Let cool slightly. Drip over chilled cake edges and let it run down naturally.

  • Decorate with spooky sprinkles and let the cake set before slicing.

Notes

  • Do not overmix the batter to keep the cake light.

  • Chill the cake before adding the drip for neat drips.

  • Gel food coloring gives deeper color without thinning batter.
