I am making around 70 petits fours for a baby shower in august. In the past, I have made them out of pound cake (from a mix) and they seem pretty durable. My dilemma is that I wanted to combine 2 or more mixes and just bake in a big sheet pan.
Is this ok, or will it change the consistency of the cake. If I don't do this- I will end up doing about 4 or 5 regular pound cakes in a loaf pan. Also, if I can do this--I need someone to fill me in on how much batter to use for an 11x15 sheet pan. Also how long would I need to bake it?
When I made a 16 in cake, in the past, I mixed one box, filled the pan with batter. Mixed another box and used the second box to fill the pan to where I needed it. The cake came out great. I didn't have any problems. Is this a right way??? I don't know....but it worked for me! lol
Thanks so much YA'LL ( as we say here in Alabamy! haha!). That is definitely the info that I was looking for! I will use two mixes and just fill my pan to where I need it and everything should be fine... right? 
Ya'll have been a big help. Thanks again!
