Ingredients

The following ingredients have 15 Servings
  • 2 cups (250g) all-purpose flour ((spooned and leveled))
  • 3/4 cup (65g) unsweetened cocoa powder ((spooned and leveled))
  • 1 1/4 tsp baking soda
  • 1/4 tsp baking powder
  • 3 large eggs
  • 1 3/4 cups (360g) granulated sugar
  • 2 tsp vanilla extract
  • 1 cup + 2 Tbsp (246g) Hellmann's® or Best Foods® Mayonnaise
  • 1 1/3 cups (315ml) warm water
  • Chocolate shavings, (for topping)
  • 4 large egg whites ((make sure there's not even a drop of yolk!))
  • 1 cup (200g) granulated sugar
  • 1/4 tsp cream of tartar
  • 1 tsp vanilla extract

Instruction

  • Preheat oven to 350 degrees F. Spray a 13 by 9-inch baking dish with non-stick cooking spray.
  • In a medium mixing bowl whisk together flour, cocoa powder, baking soda and baking powder for 20 seconds, set aside.
  • In a separate large mixing bowl, using an electric hand mixer set on high speed, beat eggs, sugar and vanilla for 3 minutes. Blend in mayonnaise.
  • Mix half of the flour mixture into the sugar/mayonnaise mixture, mix in the water then mix in remaining flour mixture. Pour into prepared pan. 
  • Bake in preheated oven until toothpick inserted into center comes out clean, about 34 - 38 minutes. Let cool completely on a wire rack (I like to cover about halfway through to seal in moisture). 
  • Frost completely cooled cake with marshmallow frosting then top with chocolate shavings.
