Ingredients

The following ingredients have 16 Servings
  • ½ cup unsalted butter (at room temperature)
  • ½ cup light or dark brown sugar (lightly packed)
  • ¼ cup granulated sugar
  • 1 egg (at room temperature)
  • ⅔ cup creamy peanut butter ((not natural-style))
  • 1 teaspoon pure vanilla extract
  • 1 and ¼ all-purpose flour
  • ½ teaspoon baking soda
  • ½ cup old-fashioned whole rolled oats
  • ½ cup M&Ms*
  • ½ cup  semi-sweet chocolate chips (optional)

Instruction

  • Using a hand mixer or a stand mixer fitted with a paddle attachment, cream the sugars with the butter on medium speed (it will take around 2 minutes). Then at high speed, mix in the egg, the peanut butter, and the vanilla extract (about 2 minutes). Set aside.
  • Add the flour and the baking soda, and mix on low speed until just combined. Fold in the oats, the M&M's, and chocolate chips.
  • Preheat oven to 400°F (200°C) and line two large baking sheets with parchment paper or silicone baking mats. Set aside.
  • Using a medium cookie scoop, scoop out the batter and place on baking sheets. Keep about 2 inches between the cookies as they will spread.
  • Bake for 8-10 minutes. The cookies will look soft and slightly under-baked. Remove them from the oven and allow them to cool down for 5 minutes.
  • Transfer to a wire rack to completely cool down.
