Ingredients

Scale
  • 4 large eggs
  • 1.5 cups (360 mL) dark cocoa powder
  • 2 cups (400 g) white sugar
  • ¾ cup (180 mL) vegetable oil
  • ½ cup (85 g) chocolate chips or chopped chocolate
  • ¼ tsp salt
  • 2 tsp vanilla extract
  • 1 bag mini marshmallows (10.5 oz or 5.5 cups, 298 g)
  • 2 cups (340 g) chocolate chips (or chopped chocolate)
  • 1.25 cups (300 g) peanut butter
  • 5 tbsps (71 g) butter
  • 3 cups (85 g) Rice Krispies (gluten-free if needed)

Instructions

  1. Prep Oven: Preheat oven to 350°F and grease a 9×13 inch pan to prevent sticking.
  2. Mix Wet Base: Whisk sugar, vegetable oil, eggs, and vanilla extract until smooth and glossy, creating a rich foundation for the brownies.
  3. Develop Chocolate Layer: Integrate dark cocoa powder and salt into the wet mixture, blending until uniformly chocolatey, then fold in chocolate chips for extra depth and texture.
  4. Initial Bake: Spread batter evenly in the prepared pan, baking for 17 minutes until the surface sets but remains slightly moist.
  5. Marshmallow Transformation: Blanket the partially baked brownies with mini marshmallows, returning to the oven for 8 minutes to achieve a lightly caramelized, puffy topping.
  6. Create Crispy Topping: Melt chocolate chips, peanut butter, and butter in a microwave-safe bowl, stirring between short heating intervals to ensure smooth consistency.
  7. Finish Topping: Coat Rice Krispies thoroughly with the melted chocolate mixture, creating a crunchy, glossy layer.
  8. Final Assembly: Spread the chocolate-covered Rice Krispies evenly over the cooled marshmallow surface, allowing the dessert to set completely at room temperature.
  9. Serve: Cut into square portions, revealing the indulgent layers of fudgy brownie, marshmallow, and crisp chocolate-cereal topping.

Notes

  • Oven Precision: Maintain exact 350°F temperature for consistent brownie texture and even baking.
  • Mixing Technique: Whisk wet ingredients vigorously to create a smooth, glossy chocolate base that ensures rich flavor integration.
  • Marshmallow Timing: Watch closely during the 8-minute marshmallow toasting to prevent burning and achieve perfect golden-brown caramelization.
  • Cooling Strategy: Let brownies cool completely at room temperature to help layers set and facilitate clean, precise cutting.
