Ingredients

  • 1/2 cup peanut butter creamy or crunchy
  • 1/2 cup unsalted butter melted
  • 1/4 cup granulated sugar
  • 3/4 cup brown sugar
  • 2 tsp vanilla extract
  • 1 egg
  • 1 egg yolk
  • 2 cup quick oats not old-fashioned
  • 3/4 cup all-purpose flour
  • 1/2 tsp salt
  • 1/2 tsp baking soda
  • 1 1/2 cup M&Ms regular, mini, or mix of both
  • 1/2 cup chocolate chips OR peanut butter chips OR chopped peanuts(optional)

Instructions

  • In a large mixing bowl or the bowl of a stand mixer, beat together the peanut butter, butter, sugars and vanilla extract. Add the egg and egg yolk, mix just until combined.
  • In a medium mixing bowl, whisk together the oats, flour, salt and baking soda. Gradually add the dry ingredients to the wet ingredients. Mix until a soft dough forms. Fold in the M&Ms with a spatula.
  • Let the cookie dough to stand for 15 minutes to allow the oats to absorb any excess moisture.
  • Meanwhile preheat oven to 350 degrees, line baking sheets with parchment paper or baking mats.
  • Using a standard size cookie scoop (#40 or 1.5 tbsp.) scoop balls of dough and place onto prepared sheets, gently pat to slightly flatten. Place in the oven and bake for 10-12 minutes, taking care not to overbake. The cookies will look soft, but allow them to cool on the sheets for 5 minutes before transferring them to a wire rack to cool completely.

Notes

-You can easily add peanut butter chips, chocolate chips or chopped peanuts for added flavor and texture!
