Ingredients
Scale
Brownie Batter
- 1 cup unsweetened cocoa powder
- 1/2 cup oil
- 1/2 cup unsalted butter, softened
- 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: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan thoroughly with non-stick cooking spray to prevent sticking.
- Combine 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 evenly combined.
- Add Butter and Sugar: Add the softened butter to the cocoa mixture and blend until creamy. Then stir in the granulated sugar until well incorporated.
- Incorporate Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition to ensure a smooth batter. Stir in the vanilla extract for enhanced flavor.
- Mix in Dry Ingredients: Gently fold the all-purpose flour and salt into the batter. Take care not to overmix to maintain a tender crumb.
- Bake the Brownies: Pour the batter into the prepared pan and bake in the preheated oven for 25 to 30 minutes, or until the edges are set and a toothpick inserted near the center comes out with moist crumbs.
- Add Marshmallow Topping: Remove the brownies from the oven and evenly sprinkle the 2 cups of mini marshmallows over the top. Return to the oven and bake for an additional 2 to 3 minutes until marshmallows are puffed and slightly golden.
- Cool Brownies: Let the brownies cool completely in the pan on a wire rack to allow the marshmallow topping to set properly.
- Prepare Frosting: In a separate bowl, combine the melted butter, 1/4 cup cocoa powder, evaporated milk, and 2 cups of powdered sugar. Mix until smooth and creamy, adding the remaining powdered sugar gradually to reach your desired frosting consistency. Stir in 1 teaspoon vanilla extract.
- Frost and Serve: Spread the frosting evenly over the cooled brownies. Once frosted, cut into squares and serve for a delightfully rich and gooey treat.
Notes
- Do not overmix the batter after adding flour to keep brownies tender.
- Using unsalted butter allows better control of salt content in the recipe.
- Allow brownies to cool fully before frosting to prevent frosting from melting.
- For extra fudgy brownies, consider lining the pan with parchment paper for easy removal.
- Store leftovers in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
