Ingredients You’ll Need

Makes 16 bars

For the Cookie Base:

  • 1 cup unsalted butter , melted 🧈
  • ½ cup granulated sugar
  • 1 cup packed brown sugar
  • 1 tsp vanilla extract
  • 1 large egg
  • 1 ¾ cups all-purpose flour
  • ½ tsp baking soda
  • ¼ tsp salt

For the Toppings:

  • 1 cup semi-sweet chocolate chips (or chopped chocolate)
  • 2 cups mini marshmallows
  • Optional : Crushed graham crackers, chopped nuts, or sprinkles

Step-by-Step Instructions

Step 1: Preheat & Prep

Preheat oven to 350°F (175°C) . Line an 8x8-inch baking pan with parchment paper, leaving overhang for easy removal.

Step 2: Make the Cookie Base

  1. In a large bowl, mix melted butter, granulated sugar, and brown sugar until smooth.
  2. Beat in vanilla and egg until combined.
  3. Stir in flour, baking soda, and salt until just mixed. The dough will be thick.

Step 3: Press Into Pan

  1. Press ⅔ of the dough evenly into the bottom of the prepared pan. Save the remaining dough for the topping.

Step 4: Add Chocolate Layer

  1. Sprinkle chocolate chips evenly over the dough.

Step 5: Add Marshmallows

  1. Scatter mini marshmallows over the chocolate layer.

Step 6: Crumble Remaining Dough

  1. Break the remaining dough into small pieces and scatter over the marshmallows. Don’t worry about covering completely—it creates a rustic, crumbly topping.

Step 7: Bake

  1. Bake for 25–30 minutes , until golden brown around the edges and marshmallows are puffed and lightly toasted.

Step 8: Cool & Slice

  1. Let cool completely in the pan before lifting out using parchment paper. Cut into squares and serve.
