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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Cool Completely: Allow the brownies to cool completely in the pan to set the marshmallow topping and prepare for frosting.
- 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.
- Frost the Brownies: Spread the creamy chocolate frosting evenly over the cooled brownies.
- 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.
