Ingredients

  • ¾ cup all-purpose flour regular or gluten-free measure-for-measure blend
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 ½ cups old fashioned oats
  • ½ cup unsalted butter room temperature
  • 2/3 cup peanut butter crunchy or smooth
  • ½ cup brown sugar
  • 1/3 cup granulated sugar
  • 1 large egg
  • ½ teaspoon vanilla extract
  • 1 cup mini M&M’s plus more for garnish
  • ½ cup chocolate chips

Instructions

  • Preheat oven to 350 degrees.
  • Line a 9x9 inch square pan with parchment paper or foil.
  • In a bowl, whisk together flour, baking soda, salt, and oats; set aside.
  • In a large bowl, cream together butter, peanut butter, and sugars until light and smooth, about 3 minutes.
  • Add egg and vanilla extract and beat for an additional 2 minutes.
  • With the standing mixer or beaters running on low, gradually add the flour mixture, mixing only until just combined. Stir in M&M’s.
  • Evenly press dough into the prepared pan. Bake bars for 18-20 minutes or until edges are golden and a toothpick is inserted into the center and comes out clean. Cool completely.
  • Place the chocolate chips in a small microwave safe bowl. Microwave on 50% power for 45 second intervals until the chocolate chips are melted; whisk until smooth.
  • Drizzle melted chocolate over bars and garnish with M&M’s. Let chocolate drizzle harden for about 30 minutes at room temperature or refrigerate for 15 minutes before slicing.
  • Cut bars into 9 large squares or 12 mini squares.
