Ingredients

Scale
  • For Brownie Layer:
  • 1 box (18-20oz) fudge brownie mix + required ingredients (eggs, oil, water)
  • For Filling:
  • 16 Oreo cookies (regular or double-stuff)
  • For S’mores Topping:
  • 2 cups mini marshmallows
  • 4 full-sheet graham crackers, broken into pieces
  • 1/2 cup milk chocolate chips
  • 1 tbsp butter (for greasing pan)

Instructions

  1. Prep: Preheat oven to 350°F (175°C). Grease a 9×9 inch baking pan.
  2. Brownie Base: Prepare brownie batter according to package instructions. Pour half into prepared pan.
  3. Oreo Layer: Arrange Oreos in single layer over brownie batter (about 16 cookies).
  4. Second Brownie Layer: Carefully spread remaining batter over Oreos (cookies will shift slightly).
  5. Bake: 25-30 minutes until brownies are set at edges (center will still be slightly soft).
  6. Add Toppings: Remove from oven, immediately sprinkle with marshmallows, graham pieces, and chocolate chips.
  7. Broil: Return to oven for 1-2 minutes under broiler until marshmallows are golden (watch carefully!).
  8. Cool: Let cool completely before cutting into squares (marshmallows will be very hot!).

Notes

  • For extra gooeyness, use 3 cups marshmallows
  • Substitute homemade brownie batter if preferred
  • For cleaner cuts, chill brownies before slicing
  • Store in airtight container at room temperature for up to 3 days
  • Broiling tip: Keep oven door slightly ajar to watch browning
