Ingredients you will need
- Peanut Butter: we like to use Jiffy Peanut Butter (the smooth version) but if you want a little bit of extra crunch go ahead and use your favorite type of peanut butter.
- Oatmeal: You will want to use Quaker Old Fashioned Oats, we find that the instant/one-minute oatmeal doesn’t work as well in a cookie.
- Mini Chocolate Chips: We think these Monster Cookies taste best with Mini Chocolate Chips but regular Chocolate Chips will be fine if that is all that you have.
- M&M’s: Crunchy, chocolately and colorful M&M’s are the fun mix-in that really makes these cookies stand out next to a glass of milk.
