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
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
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 the brownies don’t stick.
- Mix Cocoa and Oil: In a large mixing bowl, whisk together the oil and 1 cup of cocoa powder until the mixture is smooth and uniform.
- Add Butter and Sugar: Add the softened unsalted butter to the cocoa and oil mixture and blend until creamy. Then stir in the granulated sugar thoroughly.
- Incorporate Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition for even distribution. Stir in the vanilla extract to enhance the chocolate flavor.
- Add Dry Ingredients: Gently fold in the all-purpose flour and salt into the wet mixture, taking care not to overmix to maintain a tender texture.
- Bake Brownies: Pour the batter into the prepared pan and bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.
- Add Marshmallows: Immediately sprinkle the mini marshmallows evenly over the warm brownies and return them to the oven for an additional 2 to 3 minutes to soften the marshmallows
- Cool Completely: Remove the pan from the oven and allow the brownies to cool entirely in the pan, ensuring the marshmallows set properly.
- Prepare Frosting: In a separate bowl, mix together the melted butter, 1/4 cup cocoa powder, evaporated milk, and 2 cups of powdered sugar until smooth and creamy.
- Adjust Frosting Consistency: Gradually add the remaining powdered sugar until the frosting reaches your desired thickness and spreadability.
- Frost Brownies: Spread the frosting evenly over the cooled brownies.
- Serve: Cut the frosted brownies into squares and serve to enjoy their gooey, rich chocolate delight.
Notes
- Do not overmix the batter to keep brownies tender.
- You can use unsalted butter to better control salt levels.
- Ensure brownies are completely cooled before frosting to prevent melting.
- If mini marshmallows are not available, regular marshmallows cut into smaller pieces can be substituted.
- Store brownies in an airtight container at room temperature for up to 3 days.
