Mayonnaise is basically made from two main ingredients which are oil and eggs, two ingredients that are found in pretty much every cake recipe. That essentially makes swapping mayo for those ingredients a shortcut as you’re combining multiple ingredients into one.

Don’t worry, you won’t taste the mayo. What you will taste is a chocolate cake that is full of moisture and richness and chocolate flavor. Chocolate mayo cake also pairs perfectly with a cup of coffee or some Bailey’s and Coffee Ice Cubes.

How to Make Chocolate Mayonnaise Cake

FIRST STEP: Preheat the oven to 350 degrees. Grease and flour two 9 inch cake pans.

SECOND STEP: In a large bowl add the flour, sugar, cocoa, and baking soda. Take a whisk and whisk the dry ingredients to remove any lumps.

THIRD STEP: In a medium bowl add the mayonnaise, vanilla, and water and using a whisk mix together until smooth.

FOURTH STEP: Slowly add the wet mixture to the dry mixture and stir just until combined. Do not overmix.

FIFTH STEP: Divide the batter between the two prepared pans.

SIXTH STEP: Bake this Chocolate Mayonnaise Cake for 30 minutes or until toothpick or cake tester comes out clean.

SEVENTH STEP: Remove from oven and cool completely.

EIGHTH STEP: Ice with chocolate frosting.

Cooking Tips

Use full-fat mayonnaise for the best results.

You can use either dark Dutch cocoa or regular cocoa.

Don’t overmix the batter.

Measure your flour by using a spoon to fill the measuring cup and then level off the excess with a straight edge (like a knife).
