Chocolate Mayonnaise Cake is a moist chocolate cake in a 9×13 pan with chocolate buttercream frosting. One of my favorite recipes from Grandma!
Chocolate Mayonnaise Cake is sometimes touted as “cake without eggs,” which I find to be hilarious. Mayonnaise made with eggs. It’s primary ingredient is egg. This cake is made with eggs, just in a different form.
But wait until you hear about my mistake. While making the video for this amazingly moist chocolate cake, I accidentally added two eggs. I guess I’m so accustomed to cake needing eggs that I didn’t even think about and in they went! The good news is that it didn’t screw up the cake at all. It was still light, fluffy and perfectly soft, just a sat a little higher. Ha!
As a child I hated mayonnaise. Despised it. I would get SO upset if accidentally came on my food. So imagine my surprise when I caught a glimpse of my most beloved cake being made and it contained, gasp, mayonnaise!!!
For whatever reason, it was years until I had it again. Seeing an article on nostalgic recipes jogged my memory, so I requested the recipe from my mother.
Only seven simple ingredients make a splendid basic chocolate cake. A sheet cake made in a 9×13 pan. No messing around with parchment paper, spring form pans and leveling layers. Just an easy cake made with ingredients you probably already have.
Use whatever frosting you prefer on chocolate cake. My favorite is chocolate on chocolate, just a basic Chocolate Buttercream.

Tools for making chocolate cake from scratch:
- 9 x 13 Glass Baking Dish– an absolute essential for any kitchen! Use it for baking, marinating or storing. Get one with a lid, you’ll thank me later.
- Stand Mixer– I lived for years without one and I can tell you with 100% confidence that life with one is easier and it is worth the investment.
- Sifter– Sifting makes all of your baked goods smooth and fluffy. No more lumps! I prefer a hand crank so I can switch directions and get more sifted through faster.

Sift or whisk together flour, baking soda and cocoa powder. Set aside.
In a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, beat together water, sugar, mayonnaise, eggs (optional) and vanilla.
Slowly add dry ingredients, mixing well after each addition.
Mix dry ingredients and wet ingredients in separate bowls. Slowly add the dry ingredients to the wet, mixing while you add them.
Pour into prepared 9x13 baking dish.
Bake for 30 minutes or until it passes the toothpick test. Allow to cool completely.
