Instructions
For the Midnight Cake Layers:

  • Preheat oven to 350° F (180°C). Spray the bottom of three 8-inch round cake pans with cooking spray and line bottoms with parchment rounds. Set aside.
  • In a large mixing bowl, sift flour, sugar, black cocoa powder, baking soda, baking powder, and salt.
  • In a medium bowl or measuring cup, combine the buttermilk, coffee, oil, and vanilla, and then mix in eggs.
  • Add liquid mixture to dry ingredients and whisk until smooth, about 1 minute. Divide batter equally among the three cake pans or weigh for accuracy--each pan should weigh about 630 grams.
  • Bake the first two layers until a wooden pick inserted into the centre of the cake comes out with a only a few crumbs, about 23 minutes. Try not to over-bake. Let cakes cool in pans on a wire rack for 10 minutes, and then turn onto rack to cool completely. Repeat with the final cake layer. When ready to assemble the cake, wrap the layers in plastic wrap and chill for about 30 minutes.
