Top 100 Five-Ingredient Dinners

I am 62 years old and my mother made this for as long as I can remember. My grandmother's friend purchased the recipe from a restaurant in NY in the 1930's for $25 (A LOT of money back then) Hellman's mayonnaise works best. Also, Hershey's Cocoa Powder works better than other brands. My mom tried cheaper brands and the cake was not nearly as good.

I've made this a few times now. As mentioned by other reviewers, I only bake for 30 minutes, then turn off the oven and leave in for another five minutes. Also, when I don't have lemon juice, I use lime juice and it's a very good substitute. This is a keeper.

It was absolutely delicious! I added a little bit of Lipton onion soup mix.
