OLD FASHIONED CHOCOLATE MAYONNAISE CAKE BACKSTORY
Why would I put mayonnaise in a cake?
Yup, you heard right. When you think about it, it all makes sense, since mayonnaise is full of eggs and oil right? Until I found this chocolate cake recipe in Grandma’s Recipe Book that she had clipped from a Hellman’s Mayonnaise ad, I had no idea.
But since then, since making my very own Chocolate Mayo Cake, lots and lots of folks have shared their Mom or Grandma used to make it for them too!
I was so surprised when many of you said that this Old Fashioned Mayonnaise Cake Recipe reminded you of the cakes from your childhood! This chocolate cake recipe really struck an emotional chord with so many and that makes any baker happy!
Kind of full circle, don’t you think?
I just love it when you share your experiences. We have a great group of folks over at Easy as Pie Recipes & More. Come on over and join us!
Why do I call this awesome chocolate mayonnaise cake recipe old fashioned? Well…..
My grandparents lived on a farm and lived through the Great Depression. So I’m sure you understand that they would use up everything they could, since you didn’t know when you be able to get that something again.
Things like envelopes became note paper, and at some point, my Grandma must have come across an old financial ledger that wasn’t being used. So what did she do? Yes, you’re right. That’s when she started to write down her famous recipes.
Or she would clip them from the weekly newspaper. That’s how I found so many of her old recipes, including this one from Hellman’s Mayonnaise.
Many of these recipes were from the 40’s and 50’s, so maybe I should have used the word ‘vintage’ instead. But when I think of my Grandma, vintage doesn’t come to mind. She was a delight, and certainly very old-fashioned by today’s standards.

I remember visiting during the summer months and staying for a week or two. We always had so much fun, playing with the neighbourhood kids, catching frogs in the creek behind their house, watching thunderstorms in the summer porch.
And every once in a while, when it wasn’t too hot, Grandma would bake. Often it was her famous Date & Nut Cookies, but sometimes, if my brother and I had been on our best behaviour, she would bake a Chocolate Mayo Cake.
We often squabbled over who would get the corner piece, you know the one with all that fudgy chocolate frosting?
But usually my Grandfather would solve the squabble and take it for himself!
My husband Mark loves chocolate cake, and I’ve made several different recipes. I even recently made him the Ding Dong Cake from iambaker.net! Now that was a lot of work, but definitely worth the effort.
Mark loves my Chocolate Mayonnaise Cake too, so every now and then…..
I’m so grateful that I have all of Grandma’s recipes to this day, and you will see some of her other recipes on the blog.
I’m starting to work my way through them, so stay tuned! Her Chocolate Fudge Cake is amazing! And be sure to check out our Orange Cranberry Bundt Cake !
So making this cake was certainly a labor of love!
It’s so easy and the taste is out of this world! In my research for this post I also found similar recipes like the one from Southern Living, Taste of Home and of course an updated one from Hellman’s!
Some bakers have even created a Chocolate Mayonnaise Sheet Cake.
TIPS FOR A PERFECT CHOCOLATE MAYONNAISE CAKE
- Use fresh ingredients. Baking ingredients like flour and baking soda, even cocoa have expiry dates on them
- Grease and flour your baking pan to make it easy to serve
- I use Hellman’s Real Mayonnaise, but use real mayonnaise, not a salad dressing blend
- Follow all of the directions carefully
- Let the cake cool completely before frosting, or you will have a runny mess on your hands
As I mentioned above, Grandma was an amazing cook, raised on a farm, and had to provide hot and hearty meals to the farm hands every day for their noon dinner.
I can only imagine what time she had to get up to make the meal, since we’re talking early 1900’s and no modern-day appliances to ease the work! Well fast forward to today and her recipes still live on.

Thanks so much for being a part of You Can Live Rich On Less/Pie Lady Bakes!
I just love using a bundt pan for cake recipes, but this time I decided to use a 9X9 square pan and I’m glad I did! The cake rises beautifully, and because you grease and flour the pan, it will drop out quite nicely on an inverted cake plate.
The dark chocolate buttercream completes this rich and decadent cake. You can see my buttercream recipe right here. I think any Mom or Grandma would be happy to receive such a delightful sweet treat anytime!
