I’ll never turn down a cookie. Ever. And when I tell the family that I’m making this monster cookie recipe, you better believe that they’re running to the kitchen in the instance that they hear the timer go off for the oven. This simple cookie recipe is “scary” good.
Monster cookies are not only fun to eat but they’re also super fun to make as well. This is because you feel like when you’re making them, you’re adding in a ton of random (yet delicious!) things. Oats? Check. M&M’s? Check. Chocolate Chips? Oh, yes. (and I’ve been known to throw in a handful or two extra-long the way too, because well…why not?!)
Ever since I made these Monster Cookies one time, I knew I was never turning back. They’re giant, they’re packed full of chocolate, and they’re literally perfection in a hand-held treat.

Monster Cookie Recipe
Preheat oven to 350 degrees Fahrenheit.
Cream the butter and sugars together in a medium sized bowl using a hand mixer. Once you have a creamy texture, add the vanilla, egg, and peanut butter. Mix well.
In a separate bowl blend together the flour, cinnamon, baking soda and baking powder with a whisk. Pour the dry mixture into the bowl with the wet mixture.
Use a wooden spoon to mix all ingredients well, about 1 minute. Add the M&Ms, quick oats, and chocolate chips, and continue to blend with the spoon.
Prepare a baking sheet. Using a scoop, add the 2 inch balls of cookie dough and separate them by a few inches.
Bake cookies for 11-12 minutes, or until the edges start to brown. Remove the cookies from the oven. If you want the cookies to have extra M&M’s, now is the perfect time to add a few to the tops and press down easily. Allow the cookies to cool for a minute before placing them on a wire cooling rack.
Serve when ready!
Store in an airtight container at room temperature for up to a week.
The only real way to modify these monster cookies is to add in even more chocolate! More chocolate is always a good thing and everyone loves that!

The directions didn’t tell me when to add the oats. So I baked two batches before I realized I didn’t put any oats in. Good cookies but sad about missing the oats.
Oh no! You add them with the M&Ms and chocolate chips. 🙂
