Mayonnaise Cake- Also Known as Depression Cake

Mayonnaise Cake is sometimes touted as “cake without eggs or oil,” which I find to be hilarious. Mayonnaise is made with eggs and oil.

In fact, it only has three ingredients: eggs, oil and salt. I know this because I make my own… This cake is made with eggs, just in a different form.

OMG- MAYO Cake?

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.

Simple ingredients make a splendid basic chocolate cake. A sheet cake made in a 9×13 pan. Just an easy cake made with ingredients you probably already have.

Bump up the Chocolate

One of my biggest tricks (or secret ingredient) is instant espresso powder. Yep- I keep a jar in my pantry at all times.

Did you know that just 1 teaspoon added to any chocolate dessert will amplify the flavor tremendously? Like double!

Make sure you get the caffeine free kind though, otherwise that after dinner slice of cake might keep you up later than intended.

Frosting

Use whatever frosting you prefer on chocolate cake. My favorite is chocolate on chocolate, just a basic Chocolate Buttercream. Make sure you slather it on thick, the way frosting should be.

My second favorite is cream cheese frosting or… white chocolate cream cheese frosting! My mom made it this way and, shocker, I also hated cream cheese!

But I’m also not gonna lie- sometimes I just use a tub of store bought frosting. No shame in my game, folks.

Cake Pans

Do I have to use a 9×13 pan? Nope- you can use whatever pan you choose, however baking times will vary and since there are so many sizes, I can’t really give you a guide.

I will say that if you use two circular pans, reduce cooking time to about 22-25 minutes. Use the toothpick test and make sure it lightly springs back. To make sure both cakes are even, use a kitchen scale and weigh them.

Make Ahead & Storage

Can I freeze chocolate cake? This is a tricky one. You can freeze chocolate cake, but I do not recommend freezing the frosting.

How far in advance can I make cake? I wouldn’t make it longer than 24 hours in advance. Regardless of how you store it, cakes start to lose moisture the moment you take them out of the oven.

Do I need to refrigerate chocolate mayonnaise cake? No, you do not need to keep it chilled. In fact, chilling cakes can dry them out faster. I recommend storing covered at room temperature and then eating them up fast.
