Chocolate Mayonnaise Cake has to be one of the most decadent, delicious and easy cakes I have ever made! Simply combine all ingredients together, pour into a pan and bake.  That is it!  You will never want to use a prepared cake mix again once you try this recipe!

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!

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!

  1. I made this from the recipe and it was so thick and baked like a crater cake so lumpy and just terrible. I think you left eggs out of the recipe!!! Will never use this recipe again it was for a party and couldn’t use it.

    1. I am so sorry to hear that, Brenda! I have never had that issue before. This cake uses mayonnaise in place of the eggs so it should still turn out smooth and delicious!

  2. Easiest cake ever! My go-to when teens want dessert and I want minimal effort! They like it frosted with vanilla buttercream and mini chocolate chips!5 stars

  3. I have had mayonnaise cake before many, many years ago and absolutely loved it, but I’m wondering why this recipe doesn’t call for baking powder? I have not made this recipe yet, and I would like to, and I can’t even remember if baking powder goes into other mayonnaise cake recipes, but I do know it goes into many other cake recipes. I just want to make sure that baking powder doesn’t go into it before I use this recipe. Thank you!

    1. Yes, you can use a Bundt pan for this cake. Grease it well so the cake doesn’t stick, and adjust the baking time as Bundt pans may need a bit longer. Keep an eye on it and do the toothpick test to be sure. I would love to hear how it turns out for you, Shirley!

  4. I haven’t made a mayonnaise cake in ages! I’m not a cake lover, but this cake is amazing! The most moist I’ve ever had. Yummy! Thank you for reminding me. Now I have to go make one!5 stars

  5. This recipe never gets old. I baked it a lot as a teenager and I am going on 70. This cake is still a cirowd pleaser5 stars

  6. Moisture, delicious and easy to make. I made my own mayonnaise this week for the first time and then wondered what to do with it. So, I googled, “recipes using mayo” and decided to try this one. Holy moley was it a good idea! I followed the recipe, except for adding an additional tablespoon of flour due to living at high altitude. Oh my, this is so good!

    1. Hi Carol, we have never tried tiering this recipe but other readers have made it as directed with good results. We would love to hear how it turns out for you!

  7. What if I want to use Baker’s chocolate instead of powdered cocoa; how should I adjust the ingredients in the recipe?

    1. I have never tried this recipe with bakers chocolate. But I would love to hear how it turns out if you attempt it!

  8. No where could I find how many servings you are basing your nutritional information on. That is EXTREMELY important to someone who needs to know the net carbs information for medical reasons.

    1. Sorry for the confusion Wally. The nutrition information is for one serving which is 1/16 of the cake. If knowing the exact nutritional information is important for medical reasons, we recommend using a nutrition app like MyFitnessPal and inputting the ingredients and brands that you used in the recipe for the most accurate information. I hope this helps!

  9. I love this recipe. The family loves this recipe, too. I used 1.5 tsps of baking soda because of other reviews and it set fine. I forgot the vanilla, but the cake was still delicious.
    Thank you for posting this recipe.5 stars

  10. I have made this cake before and it is amazing!! I was just wondering if it can be frozen after baking and then pulled out when ready to be decorated and eaten?

    1. I am so glad you love this cake Holly! While I haven’t frozen it, I’m sure it’ll work fine! Just make sure to wrap it really well. Enjoy!
