A great salty-sweet snack recipe for a peanut-safe Halloween party: Rold Gold Pretzel S'mores! Rold Gold Pretzels are listed on the Snack Safely peanut-free, tree-nut-free, egg-free list. Use peanut-free chocolate, like Enjoy Life, and your choice of peanut-free marshmallow creme..
Just saw these at Target last night! Annie's Homegrown is good about labeling for cross-contamination, and their Honey and Chocolate flavor bunny grahams crackers are listed on the handy peanut-safe snack list available on their website. (Note: The Halloween package listed shared equipment with milk and soy.)
You could easily make this recipe peanut-free by using peanut-safe food coloring and marshmallows. Kellogg's is very good about labeling for cross contamination and Rice Krispies cereal is considered safe for people with peanut allergies.
