This recipe for a copycat of the famous Portillo’s chocolate cake is hardly new…you can find it all over the internet. And the special ingredient, mayonnaise, is hardly unique to Portillo’s…I’ve seen decades-old cake recipes use mayo as an ingredient. But just in case you’ve never run across this recipe for an amazingly moist chocolate cake with tons of frosting, I thought I’d share it here, too! It’s perfect for a birthday or other celebration!!!
- 1 box devil’s food cake mix
- 3 eggs
- 1 cup ice-cold water
- 1 cup mayonnaise
- 2-3 tubs milk chocolate frosting (yes, canned frosting, and you really can’t use too much!)
- Sprinkles (optional)
Preheat oven to 350.
Grease and “flour” (since it’s a chocolate cake, I used cocoa powder) two cake pans.
Combine cake mix, eggs, water, and mayonnaise in large bowl. Mix on low for 30 seconds. Increase to high and mix for 5 minutes more.
Pour into prepared pans and bake for 30-35 minutes, testing with a toothpick for doneness.
Cool on wire racks for 10 minutes. Turn out cakes and cool completely.
Level cake tops and frost the cake with lots of chocolate frosting. Seriously…Portillo’s uses two pounds of frosting in each of their chocolate cakes, so use more than you think you should! Top with sprinkles if desired.
