  • Total Time: 55 minutes
  • Yield: 1012 servings 1x

Ingredients

Scale
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • ¾ cup unsweetened cocoa powder
  • 1 ½ teaspoons baking powder
  • 1 ½ teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup mayonnaise
  • 1 ½ cups warm water
  • 1 teaspoon vanilla extract

Instructions

  • Preheat the oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper.
  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  • Add the eggs, mayonnaise, warm water, and vanilla extract to the dry ingredients. Mix until just combined; the batter will be slightly thin.
  • Pour the batter evenly into the prepared pans.
  • Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
  • Cool the cakes in the pans for 10 minutes, then transfer to a wire rack to cool completely.
  • Frost with your favorite chocolate frosting and enjoy!

Notes

  • For a mocha twist, replace half the warm water with brewed coffee.
  • Store the cake at room temperature in an airtight container for up to 2 days or freeze individual slices for longer storage.
  • Top with fresh berries or chocolate ganache for an extra touch of flavor.
