  • 1/2 cup packed brown sugar- I also used Lakanto

  • 1/2 cup creamy peanut butter

  • 1 large egg

  • 1 teaspoon vanilla extract

  • 1 and 1/4 cups old-fashioned rolled oats

  • 1 cup all-purpose flour

  • 1/2 teaspoon baking soda

  • 1/4 teaspoon salt

  • 100 Reese’s Pieces

  • 600 Lily's chocolate chips

  • Preheat oven to 350 degrees F. Line cookie sheets with parchment paper or silicone mats, if desired, and set aside.

  • Using an electric mixer if possible, cream together butter, granulated sugar, and brown sugar until the mixture is very light and fluffy. Add peanut butter, egg, and vanilla and mix again until evenly combined.

  • Sprinkle oats, flour, baking soda, and salt over the mixture and mix on low speed, just until incorporated. Try not to over mix at this point!

  • Add Reese’s Pieces and chocolate chips and stir gently by hand. Scoop dough out into roughly 1-inch balls and place on cookie sheets.

  • Bake for 10-12 minutes, just until the tops are golden and barely set. They will continue to harden as they cool. Cool for about 15 minutes on the pans, then remove to wire racks to cool completely.
