“I was wanting a small serving of cake, but didn't want to make the whole box. This is what I came up with. It came out light and fluffy and hit the spot. I think it could be used with any boxed cake, but I used a Betty Crocker brand. Also, if you decide to use the real egg try beating the whole egg in a separate bowl and then pouring off about half.”
