This is definitely the world’s best monster cookie recipe because it’s made with oatmeal, which gives it a super chewy texture and helps hold all the goodies together!

To Bake Monster Cookies

Preheat the oven to 350°F and line a baking pan (or a pizza pan) with parchment paper.

Cream together peanut butter (creamy OR crunchy), molasses, and butter until fully mixed.
Add in dry ingredients and mix well.
Now is the time for the fun! Drop in the mix-ins and stir until all the ingredients are mixed together well.
Using a cookie or an ice cream scoop, drop scoops on the parchment paper, spacing them equally 3 inches apart.

Make Ahead Cookies

At this point, they cookies can be placed on a pan and frozen before baking. Once frozen, place them in a freezer bag and let them defrost overnight in the fridge. Remove from the fridge 15 minutes before baking.

Bake until the edges of the cookie are golden brown and the center is cooked. Remove from the oven, and let cool.

Optional Add-Ins

Nuts: any kind! Toast them in a saute pan about 5 minutes first to make them crunchier.
M&M’s: plain, peanut, peanut butter, all sizes, shapes, and flavors!
Dried Fruit: cranberries, raisins, blueberries, strawberries, flaked coconut, and even sliced & dried bananas!
Extra Crunch: crushed potato chips, pretzels, whoppers
Flavored Morsels: butterscotch, chocolate, caramel, or Heath

To Store Cookies

Monster cookies will last at least a week at room temperature if kept sealed in a zippered bag or sealed container. Keep your monster cookies cool so they stay firm.

Chances are though, the best monster cookies don’t stay around too long!
