All you do is take a TBSP of fat-free whipped cream (slightly frozen) and 1 TBSP of peanut butter and spread it on a graham cracker. Top with another graham cracker and place in the freezer for about an hour, and voila! You have a grahamwich. (By the way, grahamwich isn't the official name of this treat. It's just what we call them...)
Now I don't have to feel so guilty about getting the late night munchies. Ha!
