    Mayonnaise Cake Recipe

    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.

    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! In fact, if you’ve read about my boxed cake mix hacks, you’ll know adding more eggs just makes for a fluffier and richer cake anyhow.

    You can totally omit the eggs if you want.

    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.

    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.

    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. 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.

    Tips for the BEST Cake Ever!

    1. Don’t overmix the batter!
    2. Sift dry ingredients, don’t skip this step.
    3. Don’t overabake. You laugh, it is the number reason for bad cake.
    4. Measure flour by spooning into the cup and leveling.

    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.

    Tools:

    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.
