Making cake with mayonnaise is an old tried and true method, but many folks are surprised when they first learn about it. Never fear, it really does work! And deliciously so, I might add... :)

SUPERB cake! The cake part is so light, it almost melts in your mouth and the frosting is rich & chocolaty. I'm not a big cake fan and have rarely baked them over the years, but I'll make an exception for this one. It's particularly nice, compared to the everything-but-the-kitchen-sink type of cakes that always seem to be served. I used all-purpose flour (didn't have unbleached) and doubled the frosting (my husband is a chocolate&frosting maniac) and it came out great. I only had to bake it 30 minutes by my oven. So very glad you found and shared this recipe!

Excellent cake and very easy to make. I used a cream cheese icing rather than the one listed with the recipe because...well...we like cream cheese icing. I made a layer cake in addition to the 9x13 sheet cake called for by the recipe. The baking time for the layer cake was 28 minutes. It was 40 minutes for the sheet cake.
