  1. Ok UPDATE!!!!! I let the cake sit overnight and tasted it again and it was Delicious!!! Sooooooo much better... So on that note I changed my rationg from 3 stars to 5! I am a true believer that you can make a delicious chockolate cake with mayonnaise lol I thought this cake was just ok...Not a bad recipe but certainly not one one that Id make again anytime soon.It does bake up fluffy and moist but it definitely is Not sweet enough so it really needs 1/2 cup more sugar. I felt like it wasnt chocolatly enough just my own personal preference.if your looking for a fast and very few ingredient chocolate cake then this recipe is Perfect!!
  2. Really good. Used the penuche frosting recommended by Debbie. Thanks!!
  3. wow!!! this was delicious!!! however...i added more coco than required and was great!!!
  4. Delicious cake! I made this for a friend who remembered her mom making it when she was young. I took the advice of another reviewer and added an extra 1/2 teaspoon baking powder and baking soda because I was using low-fat mayonnaise. The cake came out perfect, I frosted it with chocolate buttercream frosting and it was a hit, my friend and I both loved it!
  5. I have loved this cake since I was a child and my mom made it for my birthday every year. Thanks for posting it, Debbie! I accidentally used light mayo (not fat free), so I upped the amount of baking powder and soda each a half teaspoon to make up for no eggs to help the cake rise. To my surprise it came out perfect! To think it was "light" was a bonus!
