So my daughters party is tomorrow. I just got back from vacation, my husband needed to get me eggs because well, I had none. That was supposed to take 30 minutes. An hour and fifteen-ish minutes later he arrives with my eggs. I bake the cakes according to the directions, and after setting them on a cooling rack placed a piece of bread on top of each one.
