Description

Chewy brownie bars topped with melted chocolate and toasted marshmallows.


Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup semi-sweet chocolate chips
  • 1 cup mini marshmallows
  • 1 cup graham cracker crumbs

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
  2. In a large bowl, whisk together the melted butter and sugar.
  3. Beat in the eggs one at a time, then stir in the vanilla extract.
  4. In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  6. Spread half of the brownie batter evenly into the prepared baking pan.
  7. Sprinkle the graham cracker crumbs evenly over the brownie batter.
  8. Top with the chocolate chips.
  9. Dollop the remaining brownie batter over the chocolate chips.
  10. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached.
  11. Remove from oven and immediately sprinkle the mini marshmallows over the top. Return to the oven for 2-3 minutes, or until marshmallows are puffed and lightly golden.
  12. Let cool completely before cutting into bars.

Notes

  • For extra gooey marshmallows, you can briefly broil the bars for 30-60 seconds, watching carefully to prevent burning.
  • You can substitute milk chocolate chips for semi-sweet if you prefer.
