Ingredients

Instructions

  • Preheat the oven to 350°F/180°C, and lightly grease a 9x13 non stick pan. You can also “flour” it with cocoa powder for easy release.
  • In a large mixing bowl, whisk together cocoa powder and hot coffee.
  • Add sugar, baking soda, salt, mayonnaise, and vanilla. Whisk together until smooth.
  • Add the flour and whisk until just combined.
  • Pour the batter into the prepared pan (and make sure to spread it to the corners using a spatula), and bake in the center of the oven for 25-30 minutes. The cake is ready when a toothpick inserted in the center of the cake is clean or with just a few moist crumbs, and/or the cake springs back when you lightly press on the center.
  • Allow to cool completely, then sprinkle with powdered sugar or frost with chocolate buttercream. Slice into 12 pieces and serve.

Notes

  • Frosting is optional. This cake is delicious without my chocolate buttercream on top, or you can dust the top with powdered sugar. 
  • Use regular full-fat mayo for best results. 
  • In place of mayonnaise, you can use 2 eggs and ½ cup of oil.
  • This cake can also be baked in a bundt pan. Be sure to grease the pan well, and dust it with cocoa powder so that the cake is easy to release. It may take a few more minutes for a bundt cake to bake fully as well. 
  • Avoid overmixing the batter. Stir in the flour after all of the other ingredients have been mixed together, and just until combined. 
  • To Store: Store this cake covered at room temperature for up to three days. If you frost it with buttercream, store it in the fridge. 
  • To Freeze: You can freeze the unfrosted mayo cake for up to 3 months. Make sure to wrap it well before putting it in the freezer.
