Recipe Box Discovery

This chocolate mayonnaise cake recipe came from my mother's old recipe box where she kept tried and true recipes. Some of the handwritten recipes note from whom she acquired the recipe. This particular one does not mention a name, but since it is in her handwriting, I can only assume that this cake pleased her.

My husband and I decided to start trying some of the recipes from both of our mothers. They each had similar recipe boxes. It will be a nostalgic look into the past, and when we like the recipes, I'll happily share them with readers who happen to find the articles.

This cake is easy to make and is very moist, undoubtedly due to the mayonnaise.

  4. Pour into a greased and floured 9x9-inch pan.

My therapist told me the way to achieve true inner peace is to finish what I start. So far today, I have finished 2 bags of M&M's and a chocolate cake. I feel better already.
