* The peanut or non-nut butter you use will make a difference in how well these stick together. If they are not holding together well, add 1 to 2 tablespoons more peanut butter. My creamy peanut butter holds these just fine with 1/2 cup.
*you can use quick oats for this recipe, however, you might need to adjust the quantity since the mixture might be a tad sticky. If so, add more oats.
