  • 1/2 cup (1 stick) butter softened
  • 1/2 cup light brown sugar
  • 1/4 cup granulated sugar
  • 1 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 2 cups quick oats
  • 3/4 cup mini m&m's

Ganache Topping

  • cups milk chocolate chips
  • 3 tablespoons heavy cream
  • 1/4 cup mini m&m's


  • Line an 8x8 baking dish with tin foil or parchment paper. Doing this will make the bars easier to lift out and cut into squares.
  • In a mixing bowl, combine butter, brown sugar, and sugar. Beat together with a hand mixer until combined and creamy.
  • Add the peanut butter and vanilla extract. Beat together until combined.
  • Add flour, oats, and m&m's and beat on low speed until combined.
  • Press into prepared pan.
  • To make the topping: In a microwave safe bowl melt the chocolate and heavy cream for 2 minutes, stirring every 30 seconds.
    *It may not take the entire 2 minutes until it's melted. That's ok.
  • Pour the milk chocolate over the cookie dough bars and spread out evenly. Immediately sprinkle with remaining M&M's.
  • Cover the pan with tin foil and refrigerate for 2 hours. Lift the bars out by the overhang of the foil or parchment paper and cut into squares. Store the bars in the fridge.
