M&M Cookie Recipe

A soft, chewy and colorful cookie.
Prep Time 15 minutes
Cook Time 15 minutes
Servings 30 cookies

Ingredients
  

  • 1 ½ cups unsalted butter (339 grams) softened to room temperature
  • ½ cup white granulated sugar
  • ½ cup brown sugar or muscovado sugar
  • 1 tsp vanilla extract or ½ tsp vanilla paste
  • 1 egg large
  • 1 ½ cups all purpose flour
  • 2 cups quick oats
  • 1 cup smooth peanut butter
  • 1 tsp baking soda
  • ½ tsp salt
  • ¾ cup M&Ms no peanuts

Instructions
 

  • Preheat the oven to 350 F.
  • In a large bowl combine butter, sugars and egg. Beat on low with an electric hand mixer or in a bowl of a stand mixer until smooth and creamy.
  • Add peanut butter and vanilla. Mix on low until combined. Set aside.
  • In a separate large bowl, combine dry ingredients. Whisk to combine and add to wet ingredients gradually. Add ½ or 1 cup at a time, beat on low until combined, and then continue with the next batch.
  • Mix until ingredients are almost combined, a few lumps here and there are fine.
    Stir in M&Ms. The batter will be thick and a little sticky. I recommend refrigerating or freezing it. Freeze for 30 minutes to 1 hour or place in the fridge for 2 hours. (2-3 hours even better). It is important to chill the batter between the batches too.
  • The batter will resemble playdough and should not be sticky after chilling. Scoop 2 tablespoonfuls of batter, rolling it into about 2-inch balls. 
  • Arrange the cookie balls on a baking sheet lined with parchment paper at least 2 inches apart. Don’t press down! 
  • Bake for 10-12 minutes (the time varies due to different ovens).
  • Let cookies stand in the pan for 5-10 minutes before transferring to a wire rack.
  • The cookies will have a very soft center inside. Once they cool down they will set well and the texture inside remains soft, chewy and buttery.
