🔪 Instructions
This is an overview of the instructions. Full instructions are in the green recipe card at the bottom of the page.
- Sift dry ingredients into a large bowl and set aside.
- Beat sugar and mayonnaise; add eggs and vanilla.

Mayonnaise cake frosting

🥫 Storage
Chocolate mayonnaise cake can be stored at room temperature in a cake holder or carefully covered with plastic wrap. It will be fine for up to 4 days or so.
It freezes well for up to 4 months when stored in an airtight container.
📖 Variations
To make a chocolate mayonnaise sheet cake -
- Follow the instructions through creating the batter. Nothing will change.
- Grease and flour a 13x9-inch baking pan.
- Pour batter into the pan and smooth the top with a spatula or knife.
- Hold it about 3 inches off the counter and drop it (don't do this with glass dishes!). It sounds weird but it breaks up and large bubbles.
- Bake it for 30 - 35 minutes, or until a toothpick inserted in the center comes out clean. Start checking it at 25 minutes.
- Cool in the pan until completely cool.
- Frost the top of the cake with a thick layer of your favorite frosting.
- For a special occasion try adding a few of these homemade chocolate covered cherries around the top.
💭 Things to know
Expert Tip: I dust my cake pans for chocolate cake with cocoa. That way any cocoa that clings to the crust of the cake it the same color as the cake. Just do it the same way you do with white flour...spoon a little into a greased pan and shake it around until it covers all surfaces then dump it out.
- For best results make sure all ingredients are at room temperature before you begin.
- If you've had a problem with cakes sticking to the pans in the past then place a round of parchment paper in the bottom of the pans and grease it then dust with cocoa. The bottom will come loose without a problem and you can just peel the parchment paper off after it's done.
- Don't scoop the flour from the container when measuring. Use a spoon and spoon the flour lightly into the measuring cup. Level it off with the flat edge of a butter knife.
- Don't use reduced fat, olive oil, canola oil, fat free, Miracle Whip or other mayonnaise variation. Use the old fashioned, full fat mayonnaise - I suggest Hellman's or Dukes mayonnaise, depending on where you live.
- Pour batter into the pans and bake immediately. Once the leavening is wet it starts to lose strength and your cake won't rise as well.
- Don't over bake your cake. Check it by inserting a wooden pick into the center of the cake. If the toothpick comes out clean with a few crumbs clinging to it the cake is ready..
- Place a couple of thin dowels or straws through the stacked cake when you are frosting the sides and top - this will keep it from sliding around. Just remove them and smooth the top before serving.
👩🍳 FAQs
Adding mayonnaise helps make the cake extra moist and tender plus the acidic component in the mayo really enhances the chocolate flavor. Be sure to use real mayonnaise and not salad dressing (like Miracle Whip).
I don't recommend it. This recipe was developed using all-purpose flour.

📞 The last word
In my experience this cake goes fast!
One of the things I like to do is bake this chocolate mayonnaise cake recipe as a sheet cake in a 13x9 inch pan, let it cool, frost it, and then cut it into squares. I flash freeze the squares individually on a cookie sheet then pop them in individual freezer containers.
They're perfect for tucking into school lunches. Be careful though - if you use freezer bags the frosting will be a mess.
This old fashioned recipe results in a moist cake that is perfect at birthday parties and family get-togethers.

DON says
Never had a cake with Mayonnaise in it! Little hesitant
Lou says
Hi, this cake looks amazing. Could I please ask how you make the glaze for the outside of the fudge frosting in the photo? Thank you kindly.
Marye says
There isn't a glaze on it, Lou - it's just the frosting.
Barbe says
This cake was delicious. I gave it only 4 stars due to recipe errors. The cake batter does not state how much salt to use (I used a pinch). The frosting instruction does not state to put in corn syrup (I added it and all was well)… great cake- needs recipe corrections c 2.
Janice says
Do you think I can substitute canola Mayo in for butter in the frosting. I can’t eat butter due to the saturated fat.
Marye says
I've never tried. Im sure you could substitute some sort of margarine?
Kim A says
Did anyone have frosting that turned out like a wet ganache, rather than a fluffy buttercream frosting? I found the hot coffee melted the creamed butter, making it a very wet frosting that did not hold up between layers.
Mary says
Can we use milk chocolate instead of dark chocolate? Thank you
Marye says
Yes, or semi sweet. But it will have less of a chocolate flavor.
Marye Audet says
No
Marye Audet says
Nope. It's correct.
