This chocolate mayonnaise cake has long been a favorite with my family. Mayonnaise is the secret ingredient in this super easy, moist chocolate cake and the optional peanut butter frosting is amazing. Mayonnaise replaces the eggs and oil in this easy chocolate cake.
This is frosted with the included fluffy peanut butter frosting, but feel free to dust the cake with powdered sugar or use a fluffy caramel cream cheese frosting or a basic butter frosting.
