This is a recipe that I sort of made up using healthy ingredients that I like and want my children to eat. I warn you, they are addicting, especially if you LOVE peanut butter. I have tried other protien bar recipes but like the crunchiness that these bars afford. Plus with the powdered milk, you have calcium, too! Do try to use the brand names that I mention, they are healthy, high in protien, vitamins, and have no trans fats. ENJOY.
