I have been asked to make dozens of cupcakes or mini loaf cakes as a fundraiser for my son's football team at our small community fair. We will be there about four hours.

If I make Indydebi's buttercream (in CC recipe section) in about three colors and keep the decorating bags in a cooler and just offer a simple decoration on top of the treat as a child buys one, would this be considered safe? Would you suggest something different? Are there concerns that I should consider?

I did not want to decorate in advance and have them sitting out in the heat, I think they would just be a melted mess and maybe unsafe?

I appreciate your thoughts, advice and/or suggestions. I am new to selling products in a hot, outdoor setting.

Decorate in advance. Indy's bc will be fine. You do NOT want to decorate to order, even a simple swirl.

Decorate them in advance and keep them in a cooler with ice packs. I do this every week for a farmer's market and it works fine. If you can find those plastic cupcake containers like you see at grocery stores it makes it even easier.

I have been doing farmers markets for 2 years now, and I use SMBC and haven't had a problem with it as far as someone getting sick. I keep them out of the sun. That, not heat seems to be my worst enemy. I also have kept them on ice packs in my under my containers, (and yes I realize that cold air flows down). With SMBC, I just bring my eggs up to 165 degrees while mixing it with the sugar, and that kills salmonella. Haven't had any complaints.

let me preface- sorry to hijack but
Leah_s- is there a safety reason to not decorating to order or do you just say that because it would be a PIA? I ask because I may need to do that in the future and just want to make sure that I am not doing anything that would question safety.
