Aloha from Hawai‘i,
Even though it's a few years since you posted this message, I'm glad that I persisted to find cake recipes with mayonnaise.

Your work to find these recipes helped me to use up the cake flour, mayonnaise and blueberries, which I put off too long to bake.

I really appreciate all of your research in finding all of these recipes. I took a long time, before I found satisfactory recipes, which did not include chocolate. Oh, don't get me wrong, I love chocolate. But, I wanted to bake cakes, which did not need chocolate in the recipe.
