This cake is very similar to this Duke’s Chocolate Mayonnaise Cake, but in a much easier to make sheet cake form. It will be a hit at your next potluck or cookout.

Mayonnaise cakes became popular in the 1970s. This particular Chocolate Mayonnaise Sheet Cake is moist, dense, and so full of chocolate flavor.

Recipe Tips:

It has a little cinnamon in it for extra flavor. If you’re not a fan of cinnamon with chocolate, you can leave it out.

Mayonnaise is made from oil and eggs so it makes sense that it makes a good cake ingredient. Use a quality mayonnaise. I prefer to use Duke’s Mayonnaise, but Hellman’s is another good brand.

Be sure the water you add to the batter is hot. Hot water helps “bloom” the cocoa powder and prevents the cake from being dry.

If not eaten the day it is baked, this cake should be refrigerated.

The mayonnaise gives the cake a wonderful texture, but don’t worry, you won’t notice the flavor of the mayonnaise.
