Thanks to Jennifer B for the tip on NAFTA Gingerbread kits; they are indeed peanut free!
Here's the response from the company that I received earlier today:
Thank you for your inquiry.
NAFTA is indeed a Nut Free facility but I would suggest the following with respect to the Kits.
We manufacture the icing and cookies in our facility but purchase the candies in bulk from outside, Nut Free vendors. However my suggestion, to be absolutely certain at all times, it to purchase candies with which you have a 100% certainty and with which you have previous experience. Use those candies along with our icing and House to do your kit.
