First, I'm not a super baker and can get stressed when they have to be "perfect." I was asked to help out at a charity thing and I need to make about 150 cupcakes (regular sized - not mini) so I think that will be about 7 boxes of cake mix and will give me some extras for any mistakes. Between the mixes, frosting and cupcake liners, I'm thinking it will cost me around $18-20.
I'm picking cupcakes because it seems easiest to me, but does anyone have any suggestions for dessert bars or something similar that is easy to make, travels well and doesn't have expensive ingredients? They don't want cakes or pies. Thanks (will also cross post to the food section).
