Mayo Cake with Peanut Butter Icing

Ingredients

• 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

Directions

Preheat oven to 350 degrees F (175 degrees C). Grease a 9-inch baking dish.

Mix flour, 1 cup sugar, mayonnaise, water, cocoa powder, and baking soda together in a bowl until smooth; pour into the prepared baking dish.

Bake in the preheated oven until a toothpick inserted in the center of the cake comes out clean, 20 to 25 minutes.

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.
