All I have are the Wilton 3" pans and I am doing a wedding cake for my niece in October. I'm doing a practice cake now. I baked the 12" layer yesterday and it looks like when I put 2 layers of 3" cakes together, it will be pretty tall. Should I use 2" pans instead? Thank you all for your help. I will have a lot more questions before October!!

If you're using 2" pans be sure to double it because in my opinion it will look more professional. I was using one 2" pans and it looked small and unprofessional. Now I'm using 3" pans.

Personally, I use the 2" pans and use two cakes in each tier. If you are going to use the 3" pans I would either try to use them to get 2" cakes OR just bake one 3" cake, then torte and fill it either once or twice. Hope that makes sense.
