  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.

My twelve year old loves to bake and begged me this evening to make something but we're a day or so out from our grocery trip. We searched by ingredients for a recipe and this came up! Glad it did! These are ingredients I almost always have on hand! The family is very pleased! Thanks for posting! This will be a keeper!

Thank you, Cricket18 for posting this recipe! Years ago my dad told about his mother and aunts making mayonnaise cakes during the war because it was readily available and eggs and oil were not. I wanted to try it and I finally found a recipe from a company, but it called for eggs. I made it per that recipe and it was delicious, but I still wanted to see a REAL recipe without all the extras that the mayo was supposed to replace. I will be going home and making this cake over the weekend! Thanks so much! I knew there was someone out there that must have had this great piece of history to share. (Note, I give this five stars because I know how good it really is!)
