# How to Make It:
01 - Preheat oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper.
02 - In a large bowl, whisk together flour, black cocoa powder, granulated sugar, baking powder, baking soda, and salt until thoroughly combined.
03 - Add vegetable oil, milk, eggs, and vanilla extract to the dry mixture. Mix on medium speed until well incorporated. Gradually 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 wooden 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 until cherries release their juices. Whisk cornstarch with water, stir into the cherry mixture, and continue cooking until thickened. Cool completely before using.
06 - Heat heavy cream in a small saucepan until just simmering. Pour hot cream over chopped dark chocolate and black cocoa powder in a heatproof bowl. Let stand for 3 minutes, then whisk until completely smooth. Add black food coloring gel if deeper color is desired.
07 - Place one completely cooled cake layer on a serving plate. Using a small knife, carefully carve out a shallow circular well in the center of the cake, about 1 inch deep and 3 inches wide.
08 - Spoon cooled cherry compote into the prepared cavity, creating the hidden surprise filling. Place second cake layer directly on top, pressing gently to seal.
09 - Spread black cocoa ganache evenly over the entire cake surface using an offset spatula. Work quickly while ganache is still pliable. Refrigerate for 30 minutes until ganache sets completely.
10 - Using red food coloring gel, pipe vein-like patterns radiating from the center toward the edges. Create edible spiders from fondant or melted chocolate and place strategically on the decorated surface.
# Expert Tips:
01 -
- The dramatic reveal when you slice into that midnight black cake and hit the crimson filling never gets old, even if you know it is coming
- Black cocoa powder gives this an intensely chocolate flavor that regular cocoa cannot match, almost like an Oreo took cake form
02 -
- The cakes must cool completely before you hollow out the center or the cake will crumble and tear instead of holding its shape
- Chilling the assembled cake for at least an hour before cutting makes slicing cleaner so the red filling stays hidden until that first dramatic cut
03 -
- Use a small round cookie cutter or the back of a spoon to hollow out the cake cavity for a neat, even circle that holds the filling perfectly
- If you cannot find black cocoa powder, use regular Dutch-processed cocoa and add a bit more black food coloring to both the cake batter and ganache
