  • cups flour

  • cup firmly packed brown sugar
  • 2 large eggs
  • 2 teaspoons pure vanilla extract
  • 1 cup Ghirardelli Milk Chocolate Chips ½ cup + ½ cup, divided
  • 1 ½ cups Mini Reese's Pieces Peanut Butter Cups 3/4 cup + 3/4 cup, divided
  • cup Reese's Peanut Butter Chips
  • 2 cups Kraft Jet-Puffed Marshmallows I used the thicker marshmallow chunks - double the marshmallow!, S'moreMallows cut into sixths or just use mini marshmallows.

Instructions

  • Preheat the oven to 350°F. Grease a 9×13” baking dish and set aside.
  • In a medium bowl, whisk together the flour, salt and baking powder and set aside.
  • In a large mixing bowl, cream together the melted butter and brown sugar until smooth and fluffy, about 5 minutes.
  • Beat in the eggs and vanilla and mix well.
  • Mix in the flour mixture, ½ cup Ghirardelli Milk Chocolate Chips, 3/4 cup Reese's PB Cups,and marshmallows until just combined.
  • Spread the batter into the prepared pan and sprinkle evenly with Reese's Peanut Butter Chips, and the remaining Ghirardelli Milk Chocolate Chips and Reese's PB cups on top.
  • Bake for 35–40 minutes, until the top is golden brown.
  • Let cool and serve.

Notes

Annalise's Tip: These bars freeze great. Let them cool completely, cut,and freeze in a freezer bag or airtight container for up to 3 months. Let thaw on the counter for a few hours or overnight before serving!
