# How-To Steps:
01 - Preheat oven to 350°F. Grease and line two 8-inch cake pans with parchment paper.
02 - In a large bowl, whisk together flour, black cocoa, sugar, baking powder, baking soda, and salt until thoroughly combined.
03 - Add oil, milk, eggs, and vanilla to the dry mixture. Beat until well incorporated, then stir in hot water until batter forms a smooth consistency.
04 - Divide batter evenly between prepared pans. Bake for 35 to 40 minutes or until a toothpick inserted into the center comes out clean. Allow cakes to cool completely in pans before removing.
05 - Combine cherries, sugar, and lemon juice in a saucepan. Simmer over medium heat for 5 to 7 minutes. Whisk cornstarch with water, stir into cherries, and continue cooking until mixture thickens. Let cool completely.
06 - Heat heavy cream until just simmering. Pour over chopped dark chocolate and black cocoa powder. Let stand for 3 minutes, then whisk until glossy and smooth. Add black food coloring gel if deeper color is desired.
07 - Place one cooled cake layer on serving plate. Carefully hollow out a shallow circular cavity in the center of the cake layer.
08 - Spoon cooled cherry compote into the hollowed cavity, creating the hidden surprise center.
09 - Position second cake layer over the filled base. Press gently to secure layers.
10 - Spread black cocoa ganache evenly over entire cake surface using an offset palette knife. Refrigerate until ganache sets completely, about 20 minutes.
11 - Pipe red food coloring gel in vein-like patterns across cake surface. Create edible spiders using fondant or chocolate. Sprinkle with edible glitter if desired.
# Expert Tips:
01 -
- The black cocoa creates an incredibly deep, almost black chocolate color that photographs stunningly
- That hidden bloody surprise inside never fails to get genuine reactions from guests
- The compote can be made days ahead, making party prep much less stressful
02 -
- The cake layers must be completely cool before you carve out the cavity or the cake will crumble and tear
- Ganache consistency is everything too thick and it wont drip, too thin and it slides right off
- The cherry compote needs to be fully chilled or it will melt your ganache when you assemble
03 -
- Black cocoa powder can be tricky to find in stores, so I order mine online and keep a few extra bags on hand during Halloween season
- Room temperature ingredients are not optional here cold eggs and milk will cause your batter to separate and bake unevenly
