OT: preschool mini bday ideas

so dd wants to celebrate her birthday in preschool (she goes kindy next year so no more preschool as of Dec) and wants to make it little special as were relocating to another state. So I thought of bringing in cake and party bags for each of her friends, but it must be egg and nut free cakes. Problem is, I don't bake and to find custom made egg nut free cakes where I live is hardest.
