Monster Cookies are thick, chewy and are the ultimate cookie.They take the best parts of your favorite cookies and make one giant conglomeration. So delicious and everyone loves them.
These cookies are bright, colorful and yummy. They are filled with peanut butter, oatmeal, M&Ms and chocolate chips. Perfect for school lunches are an after school snack.
I’m not sure why these are called monster cookies but I have a couple of theories. First, they make a pretty large cookie that is loaded full of yummy ingredients. The “monster” of all cookies. Second, the texture is bumpy and maybe that resembles a monster?! Regardless of why they are called what they are-I love these cookies.
Monster cookies are great to make ahead of time and they freeze lovely. I often may enough to be able to freeze and pull out cookies when I have surprise visitors or just a hankering for something sweet.

Frequently Asked Questions
I use a couple of different methods when freezing monster cookies. One option is to fully bake the cookies, wait until they are cooled and then place in an airtight bag and place them in the freezer. The other option is freezing the dough. To do this I like to scoop each dough ball and place it on a cookie sheet. I put the cookie sheet in the freezer and once the dough balls are frozen I place them all into an airtight container and put them back in the freezer. I like to freeze them like this so the dough balls don’t all stick together.
The best peanut butter to use is a creamy peanut butter like skippy or Jif. Don’t use natural style peanut butter. It will make the texture too crumbly.
How will I know when monster cookies are done?
You don’t want to overbake monster cookies. I suggest slightly under baking them and then letting them cool on the cookie sheet for 10 minutes. This will create a crunchy outside with the softest center.
