Mayo Cake with Peanut Butter Icing Recipe

  • Cake:
  • 2 cups all-purpose flour
  • 1 cup white sugar
  • 1 cup mayonnaise
  • 1 cup water
  • 1/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • Icing:
  • 1 cup white sugar
  • 1/2 cup evaporated milk
  • 1 tablespoon margarine
  • 1/2 cup miniature marshmallows
  • 1 cup peanut butter
  • 1 teaspoon vanilla extract
  1. Preheat oven to 350 degrees F (175 degrees C). Grease a 9-inch baking dish.
  2. Mix flour, 1 cup sugar, mayonnaise, water, cocoa powder, and baking soda together in a bowl until smooth; pour into the prepared baking dish.
  3. Bake in the preheated oven until a toothpick inserted in the center of the cake comes out clean, 20 to 25 minutes.
  4. Stir 1 cup sugar, evaporated milk, and margarine together in a saucepan; bring to a boil and cook for 2 minutes. Remove saucepan from heat, add marshmallows, and stir to melt them completely into the mixture. Stir peanut butter and vanilla extract into marshmallow mixture until icing is smooth; pour over warm cake.
