My kid is having a birthday party in a few weeks, and I'm trying to come up with some type of treat for the party. We won't be having a traditional cake and I had been thinking of giving cupcakes away as favors, but to accommodate all of the kids attending, I need something gluten-free, dairy-free, fat-free, and nut-free (!). Any ideas? Please don't say a non-food treat; I am specifically looking for food options. I am open to having different treats for different kids. Looking for something that I could order from a bakery as I don't have time to prep something myself. Tall order, but interested in crowdsourcing some ideas. TIA.
