Ingredients

  • 1 1/2 sticks (3/4 cup) of unsalted butter, softened but still cool
  • 1 cup of smooth peanut butter
  • 3/4 cup of dark or light brown sugar
  • 1/2 cup granulated sugar
  • 1 whole large egg + 1 large egg yolk
  • 1 teaspoon vanilla extract
  • 2 1/4 cups all purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup of M&M's
  • 1 cup semisweet chocolate chips

Instructions

  • Preheat the oven to 350°.
  • Line a 13 X 9 pan with two pieces of aluminum foil, crisscrossed in the center, and with a little overhang on the sides.
  • Spray the foil with cooking spray (or grease with butter) and set aside.
  • With a mixer (stand or hand) beat the butter until smooth. 
  • Add peanut butter and beat until fluffy. 
  • Next, add the sugars and beat the mixture until it's well incorporated and slightly lighter in color.
  • Scrape down the sides of the bowl with a rubber spatula.
  • Add the whole egg, egg yolk, and vanilla and mix until just blended.  
  • With the mixer on low, add the flour, baking soda, baking powder, and salt.
  • Mix until the flour is almost fully incorporated in the dough--there should still be visible streaks of flour showing.
  • Add the M&M's and chocolate chips and gently fold by hand until fully incorporated. Do not overmix.
  • Press cookie dough into the prepared 13 x 9 baking dish.
  • Bake at 350° for 22 min, until the edges are lightly browned and puffed and the center is just set.
  • Let the bars cool completely at room temperature.
  • Once cooled, gently lift bars from the pan using the foil overhangs and set onto a cutting board.
  • Carefully remove the foil from the bars, and trim the edges if desired. 
  • Cut into 24 neat squares and enjoy!
