Chocolate Mayonnaise Cake with Peanut Butter Icing

Soooo, it’s my birthday!!!  And what better way to celebrate than with a decadently delicious cake?  This chocolate mayonnaise (yes, I know it sound weird, but I promise it just makes the cake super moist and rich and yummy) cake with a homemade peanut butter butter icing.


Not only is it delicious but it’s super easy to make.  First you mix sugar and cocoa powder.  Then you dissolve baking soda in water and add it to the sugar mix.

Then you add some flour and mayo.

Beat it until it’s well combined and pour it into a greased baking pan and put it in the oven.

You make some frosting (which I don’t have process pictures for because I got as little excited about the prospect of eating spoonfuls of peanut butter icing… oops) by beating together butter, peanut butter, vanilla, powdered sugar, and milk.  After the cake cools spread the icing over the cake.  And cut a big piece.

And pour a giant glass of milk and enjoy the decadent chocolate peanut butter deliciousness.


Amazingly delicious, chocolate and peanut butter are a match made in heaven and this cake is a shining example of that, make some for yourself and try it today, you’ll thank me, I promise.
