I use this recipe for the graham crackers. This is the best one I have found. The difference is definitely with the graham flour. These taste like graham crackers only much better than store bought. I used Bob's Red Mill Graham Flour. I bought it at our local health food store. The marshmallow recipe is Martha Stewart's. Homemade marshmallows don't even compare with store bought. Try these and you'll never go back to the fake ones at the store. You could use any shape for the crackers and marshmallows. Using a square with a small shape cut out of the center would make a really cute cracker. Possibilities are endless.
