CHOCOLATE MAYONNAISE CAKE WITH BROWN SUGAR FROSTING
This cake should never, ever be forgotten or lost to recipe history. It requires no eggs and no oil. Say what? Yup. That’s where the mayonnaise comes in. I mean, that’s what mayonnaise is; eggs and oil. It makes this cake SO incredible moist. If you need a go-to homemade chocolate cake, this is it! It is hands-down THE BEST chocolate cake you will make.

DO I REALLY NEED TO ADD COFFEE TO CHOCOLATE CAKE?
You don’t taste the coffee in this. It just accentuates and deepens the chocolate flavor. I learned that little trick from Ina Garten and it really does work. If you don’t keep coffee around, no worries, just leave it out. You’ll still have a moist and yummy chocolate cake!
WHAT YOU’LL NEED:
For the cake:
all-purpose flour
sugar
unsweetened baking cocoa
baking soda
water
mayonnaise
vanilla extract
brewed coffee
For the frosting:
brown sugar
butter
milk
powdered sugar
(frosting ingredients not pictured)
HOW TO MAKE CHOCOLATE MAYONNAISE CAKE:
Preheat oven to 350f degrees. Spray a 9×9 square pan with nonstick baking spray. I like the kind of nonstick spray that has flour in it. It makes removal so much easier.
In a large bowl, mix together all the dry ingredients (flour, sugar, baking cocoa and baking soda.)
In a separate bowl, whisk together water, mayonnaise, vanilla extract and coffee.
You just want to use plain, brewed coffee – no additional milk or sugar added. If you don’t have coffee, just skip this step.
Now, slowly add the liquid mixture into the dry ingredients.
Stir just until combined. It may be a little lumpy but that’s okay. You don’t want to over-stir (it makes the cake tough.)
Pour into prepared baking dish. Bake for about 30-35 minutes (until a toothpick inserted comes out clean.)
Once the cake is finished, start preparing the frosting.
In a medium saucepan, over medium heat, combine brown sugar and butter and cook until bubbly. Be sure to whisk constantly so it doesn’t burn.
Take off the heat and stir in the milk. Then gradually add in powdered sugar.
Whisk until smooth.
Now, frost the cake! Note: The cake doesn’t have to be cooled completely to top with this frosting. Work quickly. The frosting hardens fast as it cools.
Slice and serve.
I just added some chocolate and caramel chips to each serving just to make it pretty.
Enjoy!

ULTIMATE CHOCOLATE POKE CAKE
I have made this cake all my life. Made it in Home Ec class way back in 1974. It is amazing.
My Mother (god rest her soul) made this cake for me for my birthday every year since I was 3-4 yrs. old!
My FAVORITE cake!!!
Super Moist & Indescribably Delicious!!!!!
No other cake in this world can compare to the beautiful taste and moistness of this cake!!
Sometimes Mom would use a homemade buttercream frosting. Either way – DELICIOUS!!!
Margie – what a precious memory! And what an amazing Momma!!!
I have a question. Can you use “Light” Mayonnaise to make this cake?? I am dying to try this and all I have in the house is the light mayo.
If someone can email me the answer that would be great.
I am pleased that you use coffee in this cake, coffee really brings out the chocolate flavor!!
Thanks!!
I would not use light mayo. You actually need the oils in regular mayo to make this moist š
I will admit – I had my doubts. Let’s face it, mayo isn’t exactly the first thing you think of when making something sweet but …it just works! I whipped up this cake in no time – big plus – and it tastes heavenly! Great recipe to have for those times you need something quick! I can see myself making this many more times to come lol
Good, but the frosting was practically unreadable. I had to double the amount of milk to make it spreadable. Most people who tried the cake said it was delicious.
Isaiah, thanks for commenting. It’s definitely one of those frostings that you have to put on the cake while it is still warm so it will spread easier.
Made it and we all LOVED it!! Best chocolate cake ever!
Hi Sharon! Yes, I would just double the ingredients. You’ll just have to play with the baking time a bit. I’ve never done it myself so I can’t give you an exact time on that. š
I made this cake day for the first time as cupcakes. Same temp for about 28 min. They turned out great! The frosting not so much! We only had dark brown sugar tho -and it was not smooth at all. Tasted great though. Any ideas why?
Hey Lisa! Glad you enjoyed the flavor! I am thinking it was the extra molasses in the dark brown sugar. Light brown isn’t as heavy on the molasses. The frosting is supposed to set up and have almost a toffee-like texture but it should be smooth and not clumpy. š
I make this with either Mayonnaise or Miracle Whip, educed I have the most of. My husband loves Miracle Whip & I prefer Mayo in everyday foods. I must admit I prefer Miracle Whip in the cake! Either way, this cane is THE BEST!
I make this cake at least once a month we love it. I made a change and instead of using the water I use a cup of black brewed coffee and it’s so moist and brings out the taste of the chocolate even more. It’s a great recipe and i’m glad that I found a smaller recipe for it because the full 2 8 inch cake recipe is just too much for just the two of us all at one time.
I scaled this up to 200 servings and prepared it for our soup kitchen and it was as easy to make as it was delicious. Using the mayo is cheaper and less work than using eggs and oil. We also have limited time to prepare desserts, and this type of frosting can be put onto the cake when it’s still warm, which is a huge help. This is a terrific recipe and will be in our regular rotation.
Wow. Wow. Wow. How amazing are you Barbara!? First, I just want to say thank you for your service to others. There is nothing more important in this world than to be of service to our fellow humans. Secondly, I am thrilled you made this homemade recipe – and for 200 people!! I am in awe! Thank you so very much for taking the time to come back here to comment. It really means so much!
