To Make the Evil Black Velvet Cake:
  1. Preheat the oven to 350 degrees. Prepare three 8-inch pans with cooking spray, set aside.
  2. In a large bowl sift the flour, baking soda, baking powder, and salt, set aside.
  3. Put the cocoa powder in a small bowl, and pour the hot coffee on top of it. Whisk the coffee and cocoa together until smooth, and then set aside until cooled.
  4. With a stand mixer fitted with a paddle attachment, beat the butter and sugar together until pale and fluffy, about 3 to 5 minutes.
  5. Add the eggs, one at a time, until they completely combined. Add in the vanilla.
  6. Gently add half of the dry ingredients to the batter and half of the chocolate. Mix to combine.
  7. Repeat with the remaining ingredients and mix into a smooth batter. Add the black food coloring and mix completely in.
  8. Divide the batter evenly between the three pans.
  9. Bake the cake layers about 22 to 25 minutes, rotating halfway, until a toothpick comes out mostly clean.
  10. Let the cake layers cool completely before frosting them.
To Make the Black Chocolate Sour Cream Filling:
  1. Melt the butter in a medium size microwave-safe bowl. Add the chopped chocolate and stir until it is almost fully melted. Microwave at 50% power for another 30 seconds and stir until chocolate is fully melted.
  2. Scrape into a large stand mixer bowl. Stir in the room temperature sour cream and then the vanilla. Fit the mixer with a paddle attachment. Add the powdered sugar, 1 cup at a time, and beat until smooth and creamy. For thinner frosting, add a little milk.
To Make the Devil Red Frosting:
  1. In a bowl, sift together the confectioners' sugar and cocoa powder.
  2. In the bowl of a stand mixer fitted with a paddle attachment, add butter and beat on a high speed for 2 minutes. Scrape down the sides and bottom of the bowl.
  3. Reduce the speed to low and the add in sugar/cocoa mixture.
  4. With mixer on low speed, add in milk, red food coloring and vinegar.
  5. Beat on low/medium low speed until smooth.
To Make the Black Chocolate Ganache:
  1. While the cake chills, make the chocolate ganache. Place the chocolate in a medium bowl; set aside.
  2. In a microwave safe measuring cup, heat the cream until it bubble around the edges, about 1 to 2 minutes. Pour the warm cream over the chopped chocolate and let sit for 2 minutes.
  3. Whisk from the center outward, gradually stir from the center outward until the ganache is completely smooth. Whisk in the black food gel. Set aside to cool, whisking occasionally, until it has thickened slightly, yet still a pourable consistency.
To assemble the Cake:
  1. Level off the cakes, so each layer is flat.
  2. Frost each layer with a ring of Devil Red frosting to create a "moat" for the filling. Spoon in an even layer of the Black Chocolate Sour Cream filling. Stack the next layer on top and repeat the process.
  3. Do a light crumb coating on the outside of the cake and let the cake chill in the refrigerator for 15 minutes.
  4. Frost the cake with a final coat of frosting. Let the cake chill for a final 15 minutes
  5. Carefully pour ganache onto the top of the cake. Smooth it with an off set spatula.
  6. Decorate with black sprinkles.
