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.
