Ingredients
  

Cake

  • 2 T unsalted butter
  • 3 large eggs
  • 1 1/4 cups granulated sugar
  • 1 1/4 cups mayonnaise (Hellmann's)
  • 3/4 cup unsweetened dark cocoa powder + 1 additional tablespoon
  • 2 tsp instant coffee granules
  • 2 tsp baking soda
  • 1/4 tsp baking powder
  • 1/2 tsp kosher salt
  • 2 1/4 cups all-purpose flour
  • 1 1/2 cups hot water

Frosting

  • 2 egg whites
  • 1 1/3 cups granulated sugar
  • 1/4 tsp cream of tartar
  • 1 T water
  • 1 T light corn syrup
  • 1 tsp vanilla extract

Topping

  • 4 oz semi sweet chocolate melted, hardened, and curled

Instructions
 

  • Preheat the oven to 350 degrees F. Thoroughly grease the bottoms and sides of three 8-inch round cake pans with the butter.
  • Make the cake batter. In the bowl of a stand mixer fitted with the whisk attachment, beat the eggs and sugar on high speed until light, fluffy, and lemon-colored... about 5 to 8 minutes.
  • In a medium bowl, whisk together the mayonnaise, cocoa powder, coffee granules, baking soda, baking powder, and salt.
  • Remove the bowl from the mixer and whisk the mayonnaise mixture into the egg mixture until smooth. Stir in the flour until well combined.
  • Gently stir in 1 1/2 cups hot water. Mix until all of the ingredients are thorougly combined.
  • Bake the cake layers. Divide the batter into thirds, pouring into the prepared cake pans. Bake until a toothpick inserted in the center comes out clean, 25-30 minutes. Allow the layers to cool completely before frosting.
  • Make the frosting. Make a stovetop water bath by filling a large skillet halfway with water and heating the water until it simmers. In a clean medium-size heatproof bowl, whisk together the egg whites, sugar, cream of tartar, 1 tablespoon of water, and the corn syrup.
  • Set the bowl in the water bath and wisk the mnimxture constantly (with the heat off) until it fluffs up and reaches a temperature of 140 degrees F. You can also use a mixer on low speed for this.
  • Remove the bowl from the water bath, stir in the vanilla extract, and whisk for another 1-2 minutes to cool it off a little.
  • Assemble and frost the cake! Top with chocolate curls or grated chocolate and enjoy.
