Yesterday, the pumpkin loaves were swooped up (large-size pan) and
also 2 apple pies. Unique items like coffee cake muffins, carrot cake pieces on real plates from the thrift store, and brownies if they are wrapped individually.
Cupcakes generally do not sell well, and we always have bags of cookies at the end that we pretty much give away at the end. Cookie pops, eyeball brownies, anything the least bit creepy looking (even though it's a Halloween bake sale - go figure!).
Good luck... you'll do fine if the people know they're being made by good bakers and if they're priced low.
