Ingredients

  • 16 ounces chocolate chip cookie dough
  • 8 whole graham cracker sheets
  • 2 cups mini marshmallows
  • 1/2 cup chocolate chips
  • 1/2 cup unsalted butter, melted
  • 2 large eggs
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1/4 teaspoon salt

Instructions

  1. Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or coat with nonstick spray.
  2. Press the chocolate chip cookie dough evenly into the bottom of the prepared pan.
  3. Arrange the graham cracker sheets in a single layer over the cookie dough.
  4. Sprinkle the mini marshmallows and chocolate chips evenly over the graham crackers.
  5. In a mixing bowl, whisk together the melted butter, eggs, granulated sugar, and vanilla extract.
  6. Add the flour, cocoa powder, and salt, stirring until a smooth brownie batter forms.
  7. Carefully spread the brownie batter over the marshmallow layer using a spatula.
  8. Bake for 35 to 40 minutes, until the edges are set and the center is slightly soft.
  9. For extra s’mores flavor, sprinkle additional mini marshmallows on top during the last 5 minutes of baking.
  10. Remove from the oven and allow the brownies to cool completely for about 30 minutes.
  11. Slice into 16 squares and serve.

Notes

  • Boxed brownie mix can be substituted for the homemade brownie layer.
  • Peanut butter cookie dough creates a rich flavor variation.
  • Milk chocolate, dark chocolate, or semi-sweet chocolate all work well.
  • Add caramel drizzle after cooling for an extra indulgent finish.
  • Flavored marshmallows can be used for a fun twist.
  • Allow the brownies to cool fully before slicing for cleaner cuts.
  • Store in an airtight container at room temperature for up to 4 days.
  • Refrigerate for up to 1 week or freeze for up to 3 months.
  • Warm individual servings briefly before serving for a gooey texture.
