We're visiting with Rob Sr.'s cousin and their family this weekend, and we want to bring a dessert or some treats. Both kids are severely allergic to peanuts and tree nuts. Anyone have any ideas for treats we can bring that are guaranteed to be nut-free? (I know a lot of bakery type items are out since we can't guarantee the equipment it's made with has never touched nuts, etc... and I'm hesitant to bake stuff on my own for the same reason!)
