Chocolate Mayonnaise Cake

One ingredient can make all the difference!

You haven’t had a delicious chocolate cake until you’ve tasted this mayonnaise cake recipe. Minimal ingredients and easy to follow instructions make this cake recipe a staple in my dessert cookbook. Don’t worry if you’re not a fan of mayonnaise either….you won’t even taste it!

The best part of this cake is the consistency that mayonnaise brings to the cake. No one wants to eat a dry piece of cake! Mayonnaise is great because it helps to keep the finished product moist and almost chewy. It’s an unexpected ingredient that does wonders to make this chocolate cake recipe extra delicious!

A homemade cake is actually much easier than one might imagine, just a handful of pantry staples and we can really whip up something great. A store-bought frosting can make the process even simpler, but when we’ve got the time, we’ll definitely whip up our own from scratch.
