We're attending a BBQ about 3 hours away, and I'm going to bring a dessert... any ideas of something that will travel well? It also has to last in the car because we're leaving really early, having lunch halfway there and letting the kids nap in the car the rest of the way.
The crowd is mostly families, all the kids are 5 and under, and a few single grown ups. No idea how many people.. at least 15, maybe up to 25.
