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.

TIPS FOR A PERFECT CAKE

  • 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. Made this cake many times growing up. The one tip we used was adding the baking soda to the warm water and mixing until baking soda was completely dissolved and then adding to cake mixture. Mix well and bake. This method might help bitter taste and being too dry.

  2. I’m going to try this but I’m concerned about the mayo. You mention either mayo (hellman’s) or Miracle whip. These are two different tastes. I’m torn. Can you elaborate.

    1. Either will work in this recipe, I personally find the flavor of the mayonnaise or Miracle whip can’t be detected. I most often use Hellmann’s since it’s what I have on hand.

  3. This recipe is so good that I finished eating the mayonnaise before I even put it in the mixture. Fantastic!5 stars

  4. I have used this recipe several times and I really like it. I make a half batch and bake it in an 8” round pan. It satisfies my urge for chocolate.5 stars

  5. Tastes great but the texture and consistency is a little off. I think the batter is not wet enough. Will try and add a bit more liquid next time.4 stars

  6. I grew up on Mayonnaise Cake, but lately when I make it there is a bitter taste to it. Do you have any suggestions how to avoid this?5 stars

    1. Hi Tina, the bitter taste could be coming the cocoa powder. I would just make sure the cocoa powder is still fresh and if still coming out bitter you can try a different brand of cocoa powder or adding a little extra sugar to suit your tastes.

    1. I’m surprised that the cake was dry Barbara, we find this to be a very moist cake. Glad you love the flavor of it!

  7. Cons: It fell apart

    Pros: Moist, delicious, easy to make and goes great with ice cream or coffee.

    I will make this again!4 stars

  8. I am glad I made this cake before I read the comments. I have made it four or five times with 1 substitution, I only use Dukes. It has turned out perfect every time. I wonder if the temperature of their water could have been too cool or too hot. Thanks for another great recipe.

  9. Was really looking forward to something other than the box mix but this wasn’t it. I was disappointed. The batter tasted good but although tooth pick came out beautifully clean after about 37 minutes it wasn’t done. It had somewhat of a crisp outer layer yet wasn’t done for the most part – too pasty to eat. I read the baking tips, made no changes, measured carefully and followed the recipe exactly; used Dukes mayo and have a good working oven. Glad for those who had a good result but I will check out butter and egg recipes.2 stars

      1. I don’t get it. I followed your recipe EXACTLY and used a chocolate glaze topping. OMG. This was an amazing cake. I see a few complaints on here and wonder what they did wrong because this was the best cake I have ever made….I have to go now…need another piece.5 stars

  10. My husband grew up on this type of cake and asked me to find a recipe. What a hit! Perfect cake and easy to make. Super moist! I’ve used both light and regular Miracle Whip and it comes out perfectly each time.5 stars

  11. I just baked this. It was definitely easy. Easier than the banana bread which I have baked a few times already. The cake was crumbly and had a bitter aftertaste. What could be the cause?

    1. Hi Jamie, the crumble could be too much flour, you can check out our flour measuring guide for more information on that. As for the bitter taste, that comes from the cocoa powder. You will want to make sure your cocoa powder is fresh. Hope that helps!

      1. Thanks so much for the tips and for coming back so quickly. Much appreciated. Love watching your videos as I’m a lefty too.

  12. I made this cake exactly as directed. I did not even bake it fir all of the 30 minutes ( so it was not over baked ) It crumbled when you cut it. I usually make the Hellman’s Mayo cake.. did not really compare the two until after.. this cake has no eggs.. and less liquid.
    Not moist. Sorry but not a winner.

    1. Hi Tracey, instead of eggs we use mayonnaise in this recipe. But I am sorry to hear this cake didn’t turn out well for you. If it was too dry it may have been too much flour added to the mixture. You can check out our flour measuring guide for more info and tips.
