Remember the old fashioned mayonaise cake? It was a staple in our house when I was growing up. I like to take classic recipes and "healthy them up" a bit for my family. Not too long ago I tackled the mayo cake. It turned out really good, although different from the original. It is more like a moist, rich brownie. Really good! It's whole grain(oats are heart healthy!) and lower in refined sugar than the original. I use the mayo with olive oil because I try to use the "good fats" when possible, but if you want to make it low fat, you can use light mayo.
