Note: I have seen this recipe all over the place... not sure who to give credit to...
1 C all natural crunchy peanut butter (crunchy is better than creamy)
1 C granulated splenda
1 egg (or two egg whites, but I prefer the whole egg as it is less dried out)
Mix all ingredients. Place spoonfuls onto an ungreased cookie sheet and mold into desired shape and size. Bake at 350 degrees for approximately 10 minutes.
