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
Chocolate 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 using non-stick cooking spray to prevent sticking.
- 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 evenly combined, creating a rich chocolate base.
- Add Butter and Sugar: Incorporate the softened butter into the cocoa mixture, blending until creamy. Then, stir in the granulated sugar thoroughly to assist in building a sweet crust and sweetness in the brownies.
- Add Eggs and Vanilla: Crack in the eggs one at a time, mixing well after each addition to ensure an even texture. Stir in the vanilla extract to enhance the chocolate flavor in the batter.
- Incorporate Dry Ingredients: Gently fold in the all-purpose flour and salt, careful not to overmix to preserve the brownie’s tender crumb and prevent toughness.
- Bake Brownies: Pour the batter evenly into the prepared pan. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs but not wet batter.
- Add Marshmallows: Remove the brownies from the oven and immediately sprinkle the mini marshmallows evenly over the top. Return the pan to the oven for 2-3 minutes to melt the marshmallows slightly, creating a gooey layer.
- Cool Brownies: Let the brownies cool completely in the pan to set properly and allow easy frosting application.
- Prepare Frosting: In a separate bowl, combine the melted butter, 1/4 cup cocoa powder, evaporated milk, and 2 cups of powdered sugar, mixing until smooth and creamy.
- Adjust Frosting Consistency: Gradually add the remaining powdered sugar, mixing thoroughly until you reach your desired frosting thickness suitable for spreading.
- Frost Brownies: Spread the prepared chocolate frosting evenly over the cooled brownies with a spatula or knife, ensuring full coverage.
- Serve: Cut the brownies into squares and serve. Enjoy the rich, gooey, and chocolatey indulgence of the ultimate Mississippi Mud Brownies!
Notes
- Do not overmix the batter once flour is added to avoid dense brownies.
- Use unsalted butter for better control over salt content.
- Allow brownies to cool completely before frosting to prevent melting the frosting.
- You can substitute mini marshmallows with regular marshmallows cut into smaller pieces.
- Store brownies in an airtight container at room temperature for up to 3 days or refrigerate to extend freshness.
