These Chocolate Monster Cookies are a chocolate twist on a classic cookie. They’re soft, chewy, and loaded with oats, chocolate, peanut butter, and other sweet surprises.

The Chocolate Monster Cookies are hands-down the best cookie recipe I’ve ever made. That’s saying a lot considering the number of cookies that come out of my oven – but these take the prize. They are seriously amazing.
Monster cookies have always been a favorite – I mean, they have oats, peanut butter, chocolate chips, and M&Ms. What’s not to love? Well, when you turn them into chocolate cookies and amp up the mix-ins with Reese’s Pieces and M&Ms you get a chocolate peanut butter oatmeal cookie dream.

The base of these cookies combines chocolate, peanut butter, and oatmeal. I combine both rolled oats and instant oats so the cookies have the best texture.
Bonus is there is no chilling the cookie dough with this recipe. The cookie dough goes from bowl to baking sheet in no time at all.
How to Make Chocolate Monster Cookies
Beat the eggs in a large bowl with an electric mixer or stand mixer. Add the rest of the ingredients, one at a time, and mix well between each addition.

Use a cookie scoop to drop the dough mixture on the prepared baking sheet. Space the cookie dough two inches apart.
Bake the chocolate monster cookies for 12 minutes at 350°F. Leave them on the baking sheet for five minutes before transferring them to a wire rack.

Storage Tips
Once the cookies are completely cooled you can store them at room temperature or in the freezer.
Place them in an airtight container and they will keep well for several days at room temperature.
Or, store them in a freezer bag and they will keep well for several months in the freezer.
