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 thoroughly with non-stick cooking spray to prevent sticking.
- Mix Cocoa and Oil: In a large mixing bowl, whisk together the oil and 1 cup unsweetened cocoa powder until the mixture is smooth and well combined, ensuring no lumps of cocoa remain.
- Add Butter and Sugar: Add the softened butter to the cocoa-oil mixture and blend until creamy. Then stir in the granulated sugar evenly.
- Incorporate Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition to incorporate air and combine smoothly. Stir in the vanilla extract for enhanced flavor.
- Add Dry Ingredients: Gently fold in the all-purpose flour and salt, being careful not to overmix to keep the brownies tender and soft.
- Bake Brownies: Pour the batter evenly into the greased 9×13-inch pan and 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 the pan to the oven for an additional 2-3 minutes, just until marshmallows are slightly melted and gooey.
- Cool Completely: Remove the brownies from the oven again and allow them to cool completely in the pan at room temperature. This step helps the brownies set for easier frosting application.
- Prepare Frosting: In a separate mixing bowl, combine melted butter, 1/4 cup cocoa powder, evaporated milk, and 2 cups powdered sugar. Mix thoroughly until smooth and creamy.
- Adjust Frosting Consistency: Gradually add the remaining powdered sugar while mixing until the frosting reaches your desired thickness for spreading.
- Frost Brownies: Spread the frosting evenly over the cooled brownies using a spatula or knife to create a rich, chocolaty layer.
- Serve: Cut the brownies into squares and serve. Enjoy the gooey, decadent layers and creamy frosting.
Notes
- Do not overmix the batter once flour is added to maintain moist brownies.
- For extra gooey marshmallows, watch them carefully in the oven to prevent burning.
- Use unsalted butter to better control the salt content in the recipe.
- Allow brownies to cool completely before frosting to avoid melting the frosting.
- Store covered at room temperature or refrigerate for up to 3 days.
