Cupcakes

[Lola Bunny]

My cousin's wife asked me to make cupcakes for her son's birthday in a few weeks. It's simple enough, and she has the topping for me to put on the cupcakes. She did ask for whipped cream frosting, or at least something not too sweet. I found some recipes that I can use except the cupcakes will be left outside for the duration of the party and in Houston's weather, it'll spoil. So, here I'm hoping Aliantha could give me some expert advice. Do you have any recipes or any advice for which frosting I could use? Something not too sweet, won't spoil, not too soft so I can make a nice twirl on the cupcake. My cousin's wife said she usually mix cool whip with regular store bought frosting. I'm hoping to whip up something nice instead.
