Ingredients

1/2 cup (1 stick) salted butter, room temperature

1/2 cup packed brown sugar

1/4 cup sugar

3/4 cup creamy peanut butter

1 large egg

1 teaspoon pure vanilla extract

1/2 teaspoon baking soda

1 and 1/4 cups all purpose flour

1/2 cup quick oats

3/4 cup M&Ms (any size or variety)

1/2 cup semi-sweet chocolate chips

Instructions

  1. Preheat oven to 350 degrees. Line a cookie sheet with parchment paper or Silpat mat.
  2. In a mixer, cream the butter and sugars together on medium speed, about 3 minutes until light and fluffy. Add in the peanut butter, egg, and vanilla. Scrape down the sides of the bowl as needed. Slowly mix in the baking soda and flour. Do not overmix.
  3. Fold in the oats, M&Ms and chocolate chips by hand. Chill dough for about 30 minutes.
  4. Roll balls of dough, about 2 Tablespoons of dough per ball, onto prepared baking sheet. Press a few extra M&Ms on top for looks, if preferred. Bake for 11-13 minutes– the cookies will still look a little soft, which is recommended.
  5. Slightly press down the baked cookies with the back of a spoon, since the cookies only slightly spread in the oven. Allow cookies to cool on baking sheet for 10 minutes before transferring to a wire rack. Cookies will firm up as they cool.
