Grandma’s Chocolate Mayonnaise Cake

This cake brings me back to my Grandma’s kitchen in Missouri. Almost every year on my Dad’s birthday his mom would make him her famous Chocolate Mayonnaise Cake. I used to think, ” Eww, mayonnaise!! That’s gross! I don’t like mayonnaise.” That was until I tried it and was instantly won over. My Grandma would slice the cake and serve it in her Tupperware bowls. My Grandpa would pull the half and half out of the fridge and then he and Dad would pour it over their cake. This week my parents were visiting so I decided to make Dad a mayonnaise cake as a treat for his 60th birthday that was two weeks ago. I toyed around with it a bit to make it more nourishing. When I tasted it reminded me of Grandma’s! Dad was excited to have his cake with a glass of whole raw milk just like he used to growing up when my grandparents had a milk cow. The next day he had some more with my homemade raw vanilla ice cream, he was in heaven! I loved being able to make my Dad some of his favorite treats with wholesome ingredients and added health benefits. I’m sure this cake would be good with my butter cream icing as well.
Grandma’s Chocolate Mayonnaise Cake
2 cups flour (soft white wheat will give it lighter texture, similar to white flour)
2 cups raw milk
1 TBS acid medium (whey, apple cider vinegar, yogurt, kefir or kombucha)
1 cup homemade mayonnaise
1 1/2 cup sucanat
1/2 cup cocoa powder
1 TBS vanilla extract
2 tsp baking soda
1/4 tsp salt (I prefer Real Salt or Celtic Salt)
1. Combine the flour, milk and acid medium in bowl. Mix until the flour is completely mixed in. Cover and leave it sit on your counter for 8 to 12 hours.
2. In a small bowl combine the mayo, sucanat, cocoa powder, vanilla extract, baking soda and salt. Mix thoroughly. Add the wet mixture to the soaked dough. You may have to get both hands in the bowl and squish the dough together if it is hard. Add an additional 1/2 cup of milk to thin the batter out if necessary. Stir until all the ingredients are well incorporated.
3. Grease a 9 by 13 inch pan. Pour in your batter. Bake at 350 degrees F for 30 to 35 minutes. Poke with a fork or tooth pick. If it comes out clean the cake is done. If bits of batter are still clinging to it bake for an additional 5 minutes or until the fork/tooth pick comes out clean.

How lovely that you made it for your Dad – it must really have brought back memories for you both. Thank you for sharing this recipe with the Hearth and Soul hop.

  4. Thank you France! I hope you enjoy the cake! Let me know how it turns out!

    Sarah, thank you!

  5. That’s a pretty good looking ingredient list, especially for a dessert! I’ve never had mayonnaise cake, but I’ve always heard of it.

    I’m hosting a make-ahead meals link-up over at my blog Raising Isabella, and I’d love to have you share your post there:

    Hope to see you there!

  6. When I first heard of Mayo cake I thought the same thing. eewww. But it is so good. I have never made it myself because all the recipes floating around out there aren’t filled with processed everything. This is lovely and we could make this at home for a nice treat. bookmarked!

    I’m hosting whole food wednesdays over at Beyond The Peel. I’d love it if you came by to check it out and share.
    The post will go up tonight but here’s the link.
    Hope to see you!

  7. Bethany, thanks! I hope you like it. I have a few more soaked recipes on this site if you look on the recipe page.

    Shu Han, I owe it all the my Grandma, I would never have though to use mayp if not for her. Is your cake on your blog? Sounds amazing!

  8. that sounds great! I’m not a fan of fluffy cakes, Iliek really rich moist ones and this looks just like it!I made a flourless version a while back with oranges and chocolate. this is another great one to try, a plus that it’s soaked. and first time I’ve heard of mayo in cake, that’s a revelation!

  9. A soaked cake? Brilliant! I love it. I’ve been trying to find soaked recipes lately and this will be great for the next birthday party. Thanks for sharing it!
