Ingredients

Instructions

  • First, preheat the oven to 350ºF and spray a baking sheet with nonstick cooking spray.
  • Next, combine melted butter and brown sugar until there are no lumps. Then, add maple syrup, egg, peanut butter, and vanilla and mix again.
  • Add salt, quick-cooking oats, and baking soda and mix until everything is combined. Add in chocolate chips and m&m’s and mix one more time.
  • Refrigerate dough for 20 minutes to set.
  • Scoop 2 tablespoons of batter into your hands and form it into a ball. Place it onto the cookie sheet and slightly press down to form a cookie shape. The batter will feel a bit wet, but they will be so soft and chewy when done baking!* 
  • Repeat the process above until you've fit 6 cookies on your baking sheet.
  • Bake cookies at 350ºF for 11-14 minutes or until they begin to turn golden brown.
  • Remove cookies and let cool for a couple of minutes on the baking sheet before transferring to a wire rack to continue cooling for at least 20 minutes to firm up.

Tips & Notes

  • Cookie dough - the cookies will spread just a little bit when baking. If you don't press them down, you will get dome-shaped cookies. 
  • It might help to slightly moisten your hands before rolling the cookie dough and washing your hands in-between balls because the dough is pretty sticky.
