Mayonnaise Cake With Chocolate Frosting

"This is my father-in-law's mother's cake recipe from Oklahoma, and I'm posting it for safe keeping. Word (word in our family, that is) has it that no one made a mayonnaise cake like she did. She would always send one back with my husband's family when they made a trip out to Oklahoma to visit from Colorado. The frosting she put on it was boiled sugar frosting, and my father-in-law's father apparently liked frosting so much it was like, "How about a little cake with your frosting?" That's what I've heard anyway. ;) I've tried to make the boiled sugar frosting a couple times, but it doesn't come out right (maybe it's the Colorado altitude, maybe it's my cooking skills, maybe it was a grandma thing [she did have 50 years of making it behind her]. Who knows.), but my husband - the grandchild that loves mayonnaise cake the most out of all of them, so much so that we were gifted the "mayonnaise cake pan" upon the grandmother's passing - likes it just as much with this chocolate frosting. The frosting recipe is adapted from Hershey's and works swimmingly, whether you're a grandma or not. ;) Oh, this cake is also great when it's chilled - it makes it more dense and SO good."

Ready In:




  • For the cake: Preheat the oven to 350 degrees F and lightly grease a 9x12 baking pan.
  • Mix all ingredients in a medium bowl until you can't see any more flour.
  • Pour into the prepared baking pan and bake for 30 minutes.
  • Let the cake cool completely in the pan on a wire rack.
  • For the frosting: Place powdered sugar and cocoa in a medium bowl (I usually use a 4-cup Pyrex mesuring cup).
  • Heat butter and milk in a small microwave-safe bowl in the microwave until the butter is melted (be careful - if the heat is too high, it'll splatter!).
  • Gradually beat the butter mixture into the cocoa mixture until smooth.
  • Stir in vanilla.
  • Spread the warm frosting over the cooled cake. The frosting makes about a cup or so.

I am an active lady, and I am not the top chef in the world, but I can hold my own. I love making things that remind me of when I was little, I love trying out new recipes, and I love learning new things to cook. Most of the recipes I post are recipes I loved that I found online, but that I have tweaked just a bit. I do have some family recipes on here too. I love to bake, probably more than anything else in the kitchen. I love to bike ride. I like to read, travel, kayak (I've only been twice, but I loved it), hike, camp, basically any outdoorsy/active stuff.?
