At first glance, I thought Jessie Oleson of Cakespy made a cake-topped version of candy salad, but it's a cake on top of a real salad—and the cake batter contains mayonnaise. Are you cringing? Jessie says this:
If you're disgusted by this cake but you're one of the many who indulged in bacon-flavored baked goods in the past year, you take a long look at yourself in the mirror before you judge the mayo cake. Because what makes up mayonnaise—egg yolks, oil, vinegar—is all stuff that would go into a cake anyway.
She said it was "the most dense, moist, rich cake we've ever made." Sounds good to me!
