Oh, hello Monster Cookie Bars! Remember those insanely delicious Giant Monster Cookies from a few years back that everyone loves? Let me introduce you to their beloved cousin, the Monster Cookie Bar. This recipe for Monster Cookie Bars includes a similar ingredient list as the Monster Cookie recipe, its just made in a 9 x 13 inch pan so that you can cut them into whatever size and shape your cookie-loving-heart desires.

If you’re new to Monster Cookies, allow me to explain. Monster cookies start with a basic cookie dough recipe and then you start adding in all of your favorite mix-ins like M&M’s and chocolate chips. The beauty of the monster cookie is that you can add in anything that makes you happy — peanut butter chips, butterscotch chips, nuts, you name it…

Let’s talk about the ingredients that you’ll need…

Monster Cookie Bar Ingredient Notes:

Butter: Use unsalted if you have it, otherwise you may want to reduce the amount of salt used. Softened butter will work best. Allow the butter to sit at room temperature for 30 minutes to an hour. If you forget to take the butter out, you can also microwave it for 10-15 seconds — just long enough to soften it a bit without melting the butter

Brown sugar: light brown sugar or dark is fine – whatever you have on hand

Peanut butter: do not use natural peanut butter for this recipe.

Oats – this recipe uses quick cooking oats

Add-ins – we used chocolate chips and M&Ms but get as creative as you’d like!
