I don’t know about you, but I am chocolate-obsessed!
Today I’m going to share my favorite (and most requested!) chocolate mayonnaise cake recipe.
I’m sure you’re probably thinking…mayonnaise? I once thought this was the craziest ingredient to put in a yummy chocolate cake recipe, too. Trust me, you’ll never taste it! It just adds richness to the cake as well as makes the crumb more moist.
I am all about a quick and easy recipe, and this one fits the bill perfectly! I’m so excited to share my chocolate mayonnaise cake recipe with you today! It’s super easy and delicious – two of my favorite things!
If you’re curious about the icing I used for this yummy cake, you can find my chocolate cool-whip icing recipe right here. It’s so light and fluffy, and super easy to whip up!


The great thing about this recipe is that you don’t need a lot of ingredients!

It’s really quick and easy to whip up, as well. I hope you’ll love this cake as much as I do! 🙂

I add everything into a mixing bowl – no need to separate dry/wet ingredients. I typically use my KitchenAid stand mixer when making this cake, but it works just as well with a hand mixer!

Once the batter is nice and smooth, I add it into a 9×13 pan. I love using a throwaway pan (aluminum foil cake pan) just to make things easier, but you’re welcome to use a glass dish!

Once it’s finished baking, I keep it on the counter away from the oven to let it completely cool.

Once cooled, I split the cake in half and add some of the icing in the middle and then finally frost the top of the cake. I find it easiest to take a dish towel to flip it over onto a cutting board, then carefully cut it down the middle with a sharp knife.

Viola! The chocolate cool whip icing is a bit messy, but it is so tasty and easy to whip up! This cake will disappear quickly at any function, and if you have some picky people in your life, just don’t tell them there’s mayonnaise in it – they’ll never know!
If you use my cool whip icing with this cake, it does need to be refrigerated.
That’s a wrap on my chocolate mayonnaise cake recipe, sweet friends! Please let me know if you give it a whirl or if you have any questions!

My favorite fast food place here in Chicago (Portillo’s) does a chocolate cake with mayo too! It’s the best. Thanks for sharing this yummy recipe. Nothing beats a moist chocolate cake Ashley!

Sounds great, Jill! Let me know how you like it!
Mm this sounds so good! The recipe reminds of Portillo’s chocolate cake! Portillo’s is a chicago thing and a must for anyone that visits and their chocolate cake is so good!

I heard about this from my friend, Katherine! I live in Ohio and hadn’t heard of the place before, but that’s so neat! I will definitely check it out if I visit Chicago.
Mmm looks really tasty 💚💚 Regards!
Thank you so much, Monika! 🙂
I’m also a huge chocolate lover, but I never tried a recipe with mayonnaise! But it looks amazing so I will give it a try on the next birthday cake that I’ll make 🙂
Let me know what you think, Tiziana! I promise, you won’t be able to taste it, but it’ll be super moist! 🙂
This sounds crazy, but also like it would be so good! I may have to attempt this on my next baking adventure!

It does sound a little crazy, haha, but I promise it’s delicious!! Let me know if you give it a try!
Your picture shows a box of pudding mix but it isn’t on your list of ingredients, do you use it in this cake?
Oh, thank you so much for catching that! Yes, you add in one box of instant chocolate pudding mix. It helps to make the cake moist. 🙂
Will the Chocolate Mayonnaise Cake fit in one 9” round pan ?
Hi, Judy! I split it into two 9″ round pans and then stack them or I have used a single 9×13 pan if that would be better!
