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
- Prepare Oven and Pan: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan with non-stick cooking spray to prevent sticking and ensure easy removal of brownies.
- Mix Cocoa and Oil: In a large mixing bowl, whisk together the unsweetened cocoa powder and oil until you achieve a smooth and even mixture with no lumps.
- Add Butter and Sugar: Incorporate the softened butter into the cocoa and oil mixture, blending until creamy, then stir in the granulated sugar until fully combined.
- Incorporate Eggs and Vanilla: Add the eggs one at a time to the batter, mixing after each addition to ensure even distribution. Then stir in the vanilla extract to enhance the chocolate flavor.
- Add Dry Ingredients: Gently fold in the all-purpose flour and salt, taking care not to overmix to maintain a tender texture in the brownies.
- Bake Brownies: Pour the batter evenly into the prepared pan and bake in the preheated oven for 25-30 minutes until a toothpick inserted near the center comes out with a few moist crumbs.
- Add Marshmallows: Remove the brownies from the oven and evenly sprinkle the mini marshmallows over the top. Return the pan to the oven for an additional 2-3 minutes to allow the marshmallows to soften and slightly melt.
- Cool Brownies: Let the brownies cool completely in the pan to set, making it easier to frost and cut.
- Prepare Frosting: In a bowl, combine melted butter, unsweetened cocoa powder, evaporated milk, and 2 cups of powdered sugar. Mix until smooth.
- Adjust Frosting Consistency: Gradually add remaining powdered sugar bit by bit until you reach your desired frosting thickness and spreadability.
- Frost and Serve: Spread the creamy frosting over the cooled brownies evenly. Cut into squares and serve fresh.
Notes
- Do not overmix the batter once flour is added to ensure tender brownies.
- Use unsalted butter to control salt levels in the recipe.
- For extra gooey marshmallows, watch closely when reheating marshmallows in the oven to prevent burning.
- Allow brownies to cool completely before frosting to avoid melting the frosting.
- Store brownies in an airtight container at room temperature for up to 3 days or refrigerate to extend freshness.
