I’m definitely not a cake snob, I’m happy to use a boxed cake mix in a pinch (or even to doctor them up like in my favorite Chocolate Banana Cake).  But seriously, this Mayonnaise Cake makes even boxed cake mixes seem like work! Mix ingredients together, pour into a pan, bake…done!

If you believe you are not a baker at heart, you’ll love this Chocolate Mayonnaise Cake recipe because it’s so easy – even you can bake it perfectly!

This old fashioned Chocolate Mayonnaise Cake recipe has been around forever for good reason! It is decadent, delicious and easy!

Don’t let the idea of mayonnaise in a cake scare you away.  Mayonnaise is basically made of oil and eggs which are in pretty much every cake recipe and it truly makes this cake moist and decadent.


  • Using full fat mayonnaise produces the best results.  Light versions work but it will change the texture of the cake and make it chewier.
  • Don’t overmix the batter.  It may appear slightly lumpy but that is ok.
  • Use room temperature eggs. If your eggs are cold, place them in a bowl of warm water for a few minutes. There are no eggs in this recipe but a great tip when baking cakes in general!
  • When measuring flour it’s important to remember not to scoop it into the measuring cup directly from your flour container (this packs it down and measures too much flour). Simply spoon the flour into your dry measuring cup and level the excess off with a straight edge.
  • Do not over bake your cake.  Check it by inserting a toothpick into the cake.  If the toothpick comes out clean, your cake is good.

I can remember being a teenager and my friend’s mom made a mayonnaise cake. I have to admit that 3o years later, I still remember that moist tender cake and how amazing it was!  When I got my hands on a pile of vintage recipe books and saw this recipe again, I knew I had to make it.  There is a good reason this old fashioned mayonnaise cake recipe has been around for so long!

This old fashioned Chocolate Mayonnaise Cake recipe has been around forever for good reason! It is decadent, delicious and easy, you'll never need a boxed mix again!

You can use any kind of frosting on this cake including my One Minute Easy Chocolate Frosting  or my favorite Chocolate Ganache Frosting. This Chocolate Mayonnaise Cake is so wonderfully simple and unbelievably delicious that your friends will be asking for the recipe!

  1. The cake smelled and tasted delicious, however, when I cut into it, the cake crumbled and fell apart. Literally couldn’t get a slice. Followed the recipe exactly and used two 9 in round pans to make a layer cake. Help! What happened?

    1. Hi Dorothy, I wonder if it is because you used a smaller pan, it may have overcooked which would cause the cake to be dry and crumble. So sorry this happened to you!

  2. I made this for the first time early last month. Followed your recipe exactly and the result was PERFECT. Brought the cake to work and it was completely devoured in an hour. My boss couldn’t believe her ears when I told her it was made with mayonnaise. Thanks for sharing this easy recipe!

    1. I haven’t tried doubling this recipe so I can’t say for sure how it would bake in a larger pan. I might suggest two 9×13 pans. Let us know how it goes.

  3. I need to make a chocolate cake n I’m using the rectangular 1/2 sheet pan. Not sure what the measurements of the pan is but is this chocolate mayonnaise recipe about the same amount of 1 box of cake mix? Reason I’m asking is the pan takes 3 boxes. So if the single recipe is equivalent to 1 box I know I would need to triple the recipe.

  4. Love love love ur chocolate mayonnaise cake recipe..i did cupcakes instead of cake..they turned out perfectly..i tried a different way..instead of using cocoa powder I used Malted Milk Powder cuz I wanted to make white cupcakes..yeah they look like flat tops..not sure wat I did wrong but I’m going to keep trying to finger it…i followed ur recipe except I replaced the malted milk powder for the cocoa..they’re still good but just don’t look like a cupcake…thnx for sharing your recipes…imma try them all

    1. That sounds like a delicious variation Karis! I have only made this as written so I am not certain if the malted milk powder would affect it.

    1. This recipe works perfectly as written for us. Mayonnaise is made of oil and egg so there is no need for additional eggs.

  5. I would love to make a descent cake. And be a better cook. I would appreciate if I could get the mayonnaise cake recipe please.

  6. Its the same as what my mom made for me in the 50’s. Doesn’t fill the 9X13 so added added half again more on ingredients. Brought back memories of my mom making it for me as a kid, was my favorite

    1. This recipe doesn’t include eggs. There is information on successful cake baking in general and if a cake has eggs, they’re best a room temp.

  7. Sorry but this cake is disgusting. I followed the recipe exactly and didn’t overbake it.
    It has a weird smell and an even weirder taste
    Not enjoyable and I don’t know how I’ll gag it down.

    1. I’m sorry you didn’t enjoy it Minnie. I’ve never experienced the same problem so I can’t say for sure what went wrong for you.

        1. I usually use Hellmann’s but any kind should work (I’ve even made it successfully with Miracle Whip before). Mayonnaise usually consists of eggs and oil so it’s just another way to add fats to the recipe although I’ve never been able to taste it before.

  8. I’m sorry, Holly; after posting my question, I read the other comments and saw a question identical to mine – and your answer! Thanks.

  9. Can I make a suggestion for others who want to make a lighter version?
    I found out through many trial and errors that if you want to use a low fat mayo use a half cup and also add a half cup of 2% milk, not only is it lower calorie and less fat, but it turns out moist as well!

  10. This cake was the perfect amount of sweet and chocolate flavor that i was looking for. After cooling for a bit on the countertop, i covered with cling wrap and put in the refrigerator. I made a simple pb icing to put on top of it, however i was angry with myself that i made the icing without trying the cake first because the cake is so moist that in my opinion it didnt need icing, the cake is perfection all on its own!!!!

    1. I’ve always made this cake with success. Well, with 1 exception. I was in the hospital after delivering our 2nd son. Christmas time. My husband decided he would make it. This recipe came from his mom. I had the recipe written down. But, I used “T” for table spoon, and “t” for teaspoon. He didn’t catch on. SO, he made the recipe using 2 Tablespoons of baking soda, not 2 teaspoons! Yup. He created a Soap Cake. The chocolate mouse frosting was perfect! Unforgetable!!!

  11. I’m confused. In the tips for making a perfect cake, it says to use full fat mayo (so it’s obviously for this recipe) and room temperature eggs. But there are no eggs in the recipe. What am I missing?

    1. The tips are cake baking tips in general for all cakes. This particular recipe doesn’t have eggs so it wouldn’t apply.

  12. I am making the Chocolate Mayonnaise cake now, have question: Is the all-purpose flour sifted before measured when making the Chocolate Mayonnaise cake?

    1. The one and only frosting for this cake is…

      2 cups powdered sugar
      1 stick softened butter
      1 egg
      1 tsp Vanilla extract(real pure vanilla)
      2 Tblsp Cocoa powder

      Im eating some cake now. This recipe has been in our family for a very lkng time

  13. This is a wonderful cake, I made one and my granddaughter came by, she tried a piece, I ended up sending half with her,(She’s 15) she hates mayo. So I didn’t tell her. I’ve made her 2 more ,she took to school. She keeps asking make more please.

  14. Yes I used a spoon to put flour into measuring up. Used full fat mayo. I think 30 minutes was too long in my oven. The icing however was so good I could eat it without cake! I will make again but cut baking time. I remember my grandmother making this cake and it was so moist and so good! Thanks for posting the recipe.

      1. Oh my! I am changing my review to 10 stars! I remade this cake today, and I only baked it 24 minutes. It is soooooo moist and just plain good! Thank you for sharing this recipe. I’m going to try the Poke Cake next. Keep the recipes coming!

  15. I made this cake today and it is so dry it crumbles as you try to eat it. Followed directions to a T. Will make again but cut baking time way down.

    1. I’m sorry they didn’t work out. Did you measure the flour by scooping it out perhaps? I measure by spooning it into the measuring cup and leveling it off. Also, for this recipe, please do not use low fat or light mayonnaise. Hope that helps.

  16. Hi Holly, I want to make the cake just like you did. Please tell if you used Cake or All Purpose flour Thanks you, Dee.

  17. Wow!! What a nice cake chocolate cake. I must make this tonight. I have written this recipe. Hope it would be best and very yummy. Thanks for sharing it.

  18. When i saw this recipe i just knew as a chocoholic i was in heaven. Our son is coming over tonight for dinner so this has to be our dessert for the night. Heck, i might even skip the dinner and go straight to dessert. Thank you for the amazing recipe.

  19. I think this recipe may need an egg to bind the ingredients. While very tasty, my cake was crumbly and didn’t hold together at all well. Not sure why?

  20. Can I double this recipe and put it in 2–9 inch round pans, wondering if it changes texture?I want to make a tall double layer cake.thanks

  21. My grandma and mom always put a dob of mayo in cakes. As you said, mayo is eggs and oil, that’s what’s also in cake, but it adds so much moisture. I love that this cake is EASY and a one bowl wonder!

  22. This was the first cake I was taught to bake in Home Economics class. Exact recipe and that was 57 years ago. It is a no fail recipe. Love it. In those days I don’t think they had Fat Free or Calorie Wise mayo. I might be wrong on that.
