Ingredients

Scale

Brownie Batter

  • 1 cup unsweetened cocoa powder
  • 1/2 cup oil
  • 1/2 cup butter, softened (unsalted recommended)
  • 1 cup granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt

Topping

  • 2 cups mini marshmallows

Frosting

  • 1/2 cup melted butter
  • 1/4 cup unsweetened cocoa powder
  • 1/4 cup evaporated milk
  • 1 teaspoon vanilla extract
  • 3 cups powdered sugar

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan with non-stick cooking spray to ensure easy removal of the brownies.
  2. Mix Cocoa and Oil: In a large mixing bowl, whisk together the oil and 1 cup of unsweetened cocoa powder until the mixture is smooth and well combined, forming the chocolate base.
  3. Add Butter and Sugar: Incorporate the softened butter into the cocoa-oil mixture and blend until creamy. Next, add the granulated sugar and mix thoroughly to integrate sweetness and help form the crust.
  4. Incorporate Eggs and Vanilla: Add the eggs one at a time, beating well after each addition to ensure a smooth batter. Stir in the vanilla extract to enhance the chocolate flavor.
  5. Combine Dry Ingredients: Gently fold in the all-purpose flour and salt, taking care not to overmix to maintain tender, moist brownies with proper structure.
  6. Bake the Brownies: Pour the batter evenly into the prepared pan. Bake in the preheated oven for 25-30 minutes, until a toothpick inserted near the center comes out with moist crumbs.
  7. Add Marshmallows: Remove the brownies from the oven and evenly sprinkle 2 cups of mini marshmallows on top. Return to the oven for an additional 2-3 minutes, just enough to slightly melt the marshmallows creating a gooey top layer.
  8. Cool Completely: Allow the brownies to cool completely in the pan to set the marshmallow topping and prepare for frosting.
  9. Prepare Frosting: In a separate bowl, whisk together 1/2 cup melted butter, 1/4 cup unsweetened cocoa powder, 1/4 cup evaporated milk, and 2 cups of powdered sugar until smooth. Gradually add the remaining powdered sugar to reach desired frosting thickness.
  10. Frost the Brownies: Spread the creamy chocolate frosting evenly over the cooled brownies.
  11. Serve: Cut the frosted brownies into squares and serve. Enjoy the rich, fudgy texture with the melty marshmallow layer and luscious frosting.

Notes

  • Do not overmix the batter to keep brownies tender.
  • Ensure brownies are fully cooled before frosting to prevent melting the frosting.
  • Use unsalted butter to control the salt level precisely.
  • For a more intense chocolate flavor, use Dutch-processed cocoa powder if available.
  • You can substitute evaporated milk with regular milk, but the frosting may be slightly less creamy.
  • Refrigerate leftover brownies to maintain freshness, but bring to room temperature before serving.
