Ingredients

  • ½ cup unsalted butter softened
  • 1 cup packed brown sugar
  • 1 cup granulated sugar
  • cups peanut butter (creamy or chunky will work, it's up to you!)
  • 3 large eggs
  • 1 Tablespoon pure vanilla extract
  • cups old-fashioned oats (make sure they are gluten-free, if desired)
  • 1 teaspoon baking soda
  • cups mini M&M's candies
  • 1 cup chocolate chips

Instructions

  • Heat oven to 350 degrees.
  • Generously spray a large 12 x 18 inch rimmed baking sheet with non-stick cooking spray; set aside.
  • In a large bowl, combine butter, both sugars, and peanut butter until creamy.
  • Add in eggs and vanilla, mix well.
  • Add in oats and baking soda, mix well again.
  • Fold in M & M's and chocolate chips, using a large wooden spoon or spatula to make sure that they are fully incorporated into the dough.
  • Place the dough on the prepared pan and press dough out to the edges of the pan (using either your hands or a spatula - if you use your hands, spray them first with non-stick cooking spray to help the dough from sticking to your hands as you spread it).
  • Bake bars for 18-20 minutes, making sure to not overcook. Let bars cool for about an hour for easy cutting.
