Ingredients

  • 160 g (1 ⅓ cup) all-purpose flour
  • 1 teaspoon cornstarch
  • ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon kosher salt
  • 113 g (½ cup) unsalted butter, cold & cubed
  • 135 g (½ cup) creamy peanut butter*
  • 160 g (¾ cup) brown sugar
  • 50 g (¼ cup) granulated sugar
  • 1 egg
  • 1 egg yolk
  • 1 teaspoon vanilla bean paste or extract
  • 68 g (¾ cup) old fashioned rolled oats
  • 100 g (½ cup) m&ms
  • 85 g chocolate chips*

Instructions

  • In a medium bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt. Set aside.
  • In the bowl of a stand mixer fitted with a paddle attachment, cream together the butter and peanut butter on medium speed for 2-3 minutes.
  • Add the sugars and continue beating for 2-3 more minutes until light & fluffy.
  • Beat in the egg, egg yolk, and vanilla until fully combined.
  • Add the dry ingredients and mix on low speed until just combined.
  • Lastly, fold in the oats, m&ms, and chocolate chips with a rubber spatula.
  • Cover the bowl and place in the fridge for at least one hour or overnight.
  • Once the dough has chilled, preheat the oven to 350 degrees F (180 degrees C) and line two baking sheets with parchment paper.
  • Use a 3 tablespoon cookie scoop to portion the cookie dough onto a small parchment lined baking sheet.
  • Freeze the cookie dough for 15 minutes.
  • Place the cookie dough on the prepared baking sheets about 2 inches a part, and top with more oats, m&ms, and chocolate chips as desired.
  • Bake the cookies for about 12 minutes.
  • Allow cookies to cool completely on the baking sheet and enjoy!

Notes

  • I recommend using a thick, creamy peanut butter like Jif or Skippy.
  • I recommend using a variety of chocolate chip sizes, as well as a mixture of semi-sweet and bittersweet for visual appeal and balance of chocolate flavor.
  • To achieve perfectly round cookies, use a large cookie cutter or round glass, and gently circle around the cookies when they immediately come out of the oven.
