The best monster cookies are GIANT in size and full of peanut butter, oatmeal, chocolate chips and M&M’s. Super soft, thick, easy and delicious!

If you are looking for the Best Monster Cookies, you have come to the right place. If you don’t know what a Monster Cookie is, allow me to explain: you start with a basic cookie dough, then you add in mix-ins like chocolate chips and M&M’s. You can get creative and add in anything you enjoy including butterscotch chips, peanut butter chips, toffee pieces and chopped nuts.

Few things are better than Monster Cookies, in our humble opinion, except when you make GIANT Monster Cookies. We decided to take these cookies to a new whole level and made them giant in size. We’re talking a hand-sized cookie. These cookies are soft, thick, chewy, giant, and always a favorite!

The Best Monster Cookie Ingredient Notes

Let’s talk about the ingredients that you’ll need to make the best monster cookies.

  • Peanut Butter – you do not want to use all natural for this recipe. In general, all natural peanut butter in baking just does not work. Use a brand like Skippy or Jif for the best result.
  • Butter – salted or unsalted is fine. Whatever you have on hand. Butter is recommended over margarine for the best result. Make sure that you’ve allowed the butter to come to room temperature.
  • Eggs – room temperature is best. If you are pulling your eggs from the refrigerator right before baking, place the eggs in a cup of warm water for a few minutes to take the chill off.
  • Vanilla – vanilla extract makes these cookies taste extra amazing. Vanilla extract can be a bit pricey. I like to buy it from Costco. Their pricing is the best I have seen for real vanilla extract.
  • Old Fashioned Oats – I prefer Quaker Old-Fashioned Oats for these monster cookies, but any brand is fine.
  • Add ins – get creative here! Chocolate chips, peanut butter chips, cinnamon chips, toffee pieces – the options are endless!

You may notice that there is no salt added and that is intentional. Most peanut butter has a fair amount of salt, so no additional salt is needed.

The same goes for just about any other holiday. M&Ms come in colors for just about any holiday you could imagine so you can make these Monster Cookies for every holiday of the year! I’ve seen Easter M&M’s, Valentine’s M&M’s, Halloween M&M’s and the list goes on and on. There are so many fun ways to make these cookies for any occasion.
