This easy Chocolate Mayonnaise Cake recipe is rich and moist, using shelf stable pantry ingredients for the cake, and a warm chocolate frosting poured on top.
Make Cake Batter: In a mixing bowl combine flour, sugar, baking soda, and cocoa powder. Add mayonnaise, water and vanilla extract and stir to combine. Pour the batter into a greased 9x13inch pan.
Bake in for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Frosting: In a saucepan, mix together milk, butter, and sugar then cook over medium heat until boiling. Boil for just 30 seconds then remove from heat. Stir in chocolate chips and vanilla until smooth. Pour warm frosting over cooled cake.
