M&M Monster Cookies combine ALL of the good stuff – peanut butter, oatmeal, chocolate chips, and m&ms. There is no flour in these cookies, and you won’t even miss it!

We love these chewy cookies, and we also love eating them in bar form. Try my Monster Cookie Bars next, or some delicious Chocolate Chip Peanut Butter Blondies!

Another recipe re-do, and it’s a good one from Norma Jean’s Kitchen. Mom made the BIGGEST monster cookies. If SHE was making them, this recipe would make 24 cookies instead of the 32 that I made from the ingredients listed. Hers were GIANT monsters while mine are medium sized. So if I’m not satisfied after having just one, I’ll break one in half and eat that too. 🙂

When Mom and Dad were still able to travel on their own, they’d come down to Texas and spend a week to ten days with us. They’d come to all the soccer-baseball-football games and happily cheer on their two grandsons. Mom was known to make up a batch of these M&M Monster Cookies (or her famous Chocolate Scotcheroo Pinwheels) and bring them to the ball fields to share with the team. She loved treating the kids and parents, and I know they always appreciated Norma Jean’s homemade surprises.

Tips for making the best M&M Monster Cookies.

  1. Set your butter out a couple of hours before mixing so it comes to room temperature.
  2. Refrigerate the dough for at least two hours prior to baking.
  3. Use a cookie scoop to get uniform looking cookie balls. Press down slightly.
  4. Bake until they are slightly browned on top. These cookies look and taste better when they aren’t under-cooked.
  5. Use any mix-ins you want – different color m&ms for other occasions, nuts, or different kinds of chips.
  6. You can store the pre-cooked cookie balls in the freezer. Just quick freeze them first so they don’t stick to each other.
  7. TRY not to eat all the dough. 🙂

Here’s the truth about why this is one of my favorite cookies EVER.

  1. All that oatmeal makes them chewy.
  2. All that oatmeal makes me feel healthy eating them.
  3. All that oatmeal means you (and me) can eat them for breakfast.

Heck yes. Good thing I have a bunch of them in my freezer!

P.S. These aren’t just for Christmas time. They are for ALL the time. 🙂
