Materials

  • 16 tbsp unsalted butter softened to room temp
  • ½ cup brown sugar
  • 1 cup granulated sugar
  • 2 eggs at room temp
  • 1 cup creamy peanut butter use a creamy processed PB like JIF, not a natural one with a grainy texture
  • 2 tsp vanilla
  • 1½ cups all purpose flour
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1 tsp salt
  • 2 cup oats old fashioned
  • 1½ cups mini M&M's
  • 1½ cups chocolate chips

Instructions

  • In a large bowl, use a stand mixer or hand mixer to cream together the butter, brown sugar, and white sugar, about 2 minutes.
  • Scrape down the sides of the bowl and add the eggs, peanut butter, and vanilla and beat on high until combined and smooth, about 1 minute.
  • Next, add the flour, baking powder, baking soda, salt, and oats. Beat on a low speed until well combined. Then, mix in the chocolate chips and mini M&M's. The dough should be sticky and thick.
  • Cover with plastic wrap and refrigerate for 30 minutes. Can refrigerate for up to 3 days. Just make sure to allow it to sit out to come to room temp for 30 minutes before scooping.
  • Preheat oven to 350℉.
  • Scoop out large mounds of dough (about 3 tbsp) and use your hands to roll into a ball. Place on a parchment paper-lined baking sheet, several inches apart. You should have about 6 per sheet.
  • Bake for 15 - 17 minutes. The edges should be slightly brown, but the center still soft. Cool for 15 minutes, then transfer to a rack to continue cooling.
  • Store in a resealable container at room temp for up to a week.
