Instructions

Preheat the oven to 350°F (175°C).
Grease and flour two 9-inch round cake pans.
In a bowl, mix flour, baking powder, baking soda, and salt.
In another bowl, beat the butter, vegetable oil, and sugar until fluffy.
Add vanilla extract and eggs, mixing well.
Gradually add the flour mixture and buttermilk, alternating both until combined.
In a microwave or double boiler, melt the chopped chocolate.
Divide the batter into two bowls; mix in the melted chocolate in one.
Pour the vanilla batter and chocolate batter in alternating scoops into the prepared pans.
Use a knife to swirl the batters together.
Bake for 25-30 minutes or until a toothpick comes out clean. Let cool.
In a large bowl, beat the unsalted butter until creamy. Gradually add powdered sugar and cocoa powder, mixing well.
Add vanilla extract, salt, and enough water/cream to reach your desired consistency.
Divide frosting into two bowls; tint one bowl black and the other red with gel icing colors.
Place one cake layer on a serving plate. Spread a layer of black frosting on top.
Add the second layer and cover the entire cake with black frosting.
Decorate with red frosting drips and sprinkles on top for a spooky effect.

Notes

Ensure all ingredients are at room temperature for better mixing. Don’t over-mix the batter after adding flour to avoid a dense cake. Use a toothpick to create fun designs while swirling the batters. For vibrant colors, use gel icing color sparingly.
