WHAT IS MAYONNAISE CAKE?

Mayonnaise cake draws its name by using mayo instead of eggs and butter in the cake batter. Since mayonnaise consists mostly of eggs and oil, it works great as a substitute for those ingredients typically found in cake recipes. In fact, mayonnaise can even be added to a box cake mix to increase the richness of the flavor. 

It became a popular dessert dish during the Great Depression when families were forced to find more economical ways to recreate their favorite foods when they were unable to afford or find more expensive ingredients like eggs, milk, and butter. It continues to be a popular Southern comfort food today as well as a great choice for families looking for a rich dessert on a budget.

    4.8.2020 Made this moist, delicious, easy chocolatey cake for my brother-in-laws birthday today. D-E-L-I-C-I-O-U-S!!!! And I took it up a notch by changing the liquid to 2 cups of strong, hot coffee instead of plain water!!! Mmmmm, Mmmmmm, Mmmmmm! The only thing I experienced differently was that it took much longer to bake. But other than that, perfecto! Thank you Stephanie Keeping for this recipe!

  2. Oloyede Rukayat says

    Thanks for the recipe, I would like to know if the cake can stay out of the fridge for two days.

  3. Terry watson says

    I was curious if you could use salad dressing rather than mayo, I prefer the sweeter flavor and mayo tends to taste a bit salty

    We’ve made this for years and use a 9×13 pan. While still warm we lay Hershey bars on cake, as frosting! With a cold glass of milk-perfect

    I make cake but cut all ingredients in half then use 9 x13 glass pan in my air fryer. I reduce temp to 325 and bake 20 minutes after it is preheated. I use toothpick to test fineness. This is perfect size for my husband and me.

    I haven’t made the cake yet , I was planning on it . One question ..?isn’t there a difference ( measurement wise) from a glass measuring cup and individual cups ? (If so wet and dry ingredients ) which one do you use for the Mayo ? Thank you .

  7. Diane says

    I have made this cake just last year and everyone loved it, well I’m making it again, but this time I want to make a 6 inch cake. How would I measure the ingredients from 9 inch to 6 inch?

    This is my new go-to chocolate cake. I made the attached chocolate frosting and it was yummy but rich.

  9. Tammy says

    I’ve made this a few times now with gluten free flour and it turns out great!! I served it to a bunch of different people and no one notices the difference.
    I also use the icing recipe with earth balance butter and oat milk to make it dairy free and it’s great!! My mom was eating the frosting out of the bowl and didn’t even notice a difference. Figured I’d share in case there are any allergy-friendly needs out there!
