Simply mix all ingredients with exception of chocolate chips, together until well combined. A stand mixer is best for monster cookies as the batter will be thick.
Add in chocolate chips and bake at 350°F for approximately 15 minutes.
This recipe is so easy and makes for a delicious and hearty cookie. It is absolutely delicious without M&M's, but if you are looking for the original Monster Cookie, go ahead and add 1 cup of them in!
