I'd like to bake a small (6 in) cake with 2 layers therefore needing to bake it in 2 shifts as I don't have a second pan. Knowing that the BEST way is to get another pan (which isn't going to happen), will the 2nd cake still rise reasonably after waiting for the first to bake? It is a small cake so will certainly bake faster than a large cake so I should think that would make a difference. I guess I'm wondering how long is too long for the baking powder to sit in the wet ingredients? Thanks.
