Ingredients

  • ¼ cup unsalted butter
  • ¼ cup white sugar
  • ¼ cup light brown sugar
  • 1 large egg room temperature
  • 1 teaspoon vanilla extract
  • ¾ cup creamy peanut butter
  • 2 cups old fashioned rolled oats
  • 1 teaspoon baking soda
  • ½ cup mini chocolate chips
  • ½ cup mini m&ms

Instructions

  • Preheat your oven to 350 degrees F and line a baking sheet with parchment paper.
  • Beat the butter and sugar until well combined then stir in the egg and vanilla extract until well blended.
  • Add in peanut butter and mix well.
  • Stir in oats and baking soda then fold in the chocolate chips and m&ms.
  • Using a cookie scoop, place 12 balls of dough onto a baking sheet.  Add additional M&M’s and/or chocolate chips to top (optional).  Bake 12 minutes or until sides barely start to brown.  
  • Remove from oven and allow to stand on baking sheet for 5 minutes before transferring to cooling rack. 

Notes

  • Underbake. You’ll want the tops to be just beginning to brown. This ensures your monster cookies stay soft and chewy in the center and are not overly crisp. 
  • Portion. Use a cookie scoop to divide the dough and ensure all your cookies are equal in size and bake evenly. 
  • Don’t Overmix. Mix your ingredients until they are just combined. Continuing to beat or stir will cause them to become dense and alter their texture. 
  • Cool. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This will allow them to finish baking and set, so they don’t fall apart! 
  • Use Two Cookie Sheets. To reduce the baking time, and make this monster cookies recipe even faster, separate the cookies onto two cookie sheets. 
  • Keep an Eye on the Oven. Every oven cooks differently. So, be sure to keep a close eye on your cookies as they bake, and pull them out as soon as the tops look slightly golden brown.
  • Enjoy them warm!
