Ingredients

Scale
  • 1 18-oz (510 g) box of brownie mix
  • 2 cups mini marshmallows
  • eggs (amount as specified on box)
  • oil (amount as specified on box)
  • water (amount as specified on box)
  • ¼ cup (57 g) salted butter, softened
  • 1 ½ cups powdered sugar
  • 2 tbsps unsweetened cocoa powder
  • 2 tbsps milk
  • ½ tsp vanilla extract

Instructions

  1. Prep Station: Position the oven rack centrally and preheat to 350ºF. Choose between a 9×9″ or 9×13″ pan depending on desired brownie density.
  2. Brownie Foundation: Blend brownie mix according to package instructions, then pour batter evenly into selected pan, smoothing the surface for uniform baking.
  3. Initial Baking: Bake for 30 minutes until the brownies are almost set, maintaining a slightly soft center. Watch carefully to prevent over-baking.
  4. Marshmallow Blanket: Immediately after initial baking, liberally scatter mini marshmallows across the entire surface, creating a complete white coverage.
  5. Toasting Layer: Return pan to oven for 3 minutes, allowing marshmallows to puff and turn golden brown. Remove swiftly to prevent scorching.
  6. Frosting Creation: While brownies cool, combine butter, powdered sugar, cocoa powder, milk, and vanilla extract. Whip with electric beaters until achieving a silky, smooth consistency, adjusting texture as needed.
  7. Final Assembly: Once brownies reach room temperature, generously spread chocolate frosting over the marshmallow layer, creating a luxurious, glossy finish.

Notes

  • Oven Rack Positioning: Center the rack for even heat distribution and consistent browning, ensuring perfectly baked brownies.
  • Pan Size Selection: Choose 9×9″ for denser, richer brownies or 9×13″ for lighter, thinner versions based on your texture preference.
  • Marshmallow Melting Technique: Watch closely during the 3-minute marshmallow toasting to achieve golden, puffy clouds without burning.
  • Frosting Consistency Tip: Adjust milk or powdered sugar gradually to create a smooth, spreadable chocolate frosting that complements the marshmallow layer.
