My son has nut allergies, so I don't keep any nut products in the house. Anyway, I wanted to report that I've made both the Chocolate Peanut Butter cups and the Crispy Peanut Butter Treats using Organic Sunbutter (made from sunflower seeds), and Enjoy Life (dairy, nut, and soy-free) chocolate chips.  They are both ridiculously good!!!  Anyway, for those of you with nut allergies I wanted to let you know that these substitutions are really delicious!!  My son doesn't even eat these, but I personally don't feel comfortable eating peanut butter around him (he's only 4).  Anyway, I hope this helps.  :)
