Ingredients
Scale
Brownie Batter
- 1 cup unsweetened cocoa powder
- 1/2 cup oil
- 1/2 cup butter, softened (unsalted preferred)
- 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 (add gradually)
Instructions
- Preheat 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.
- Combine cocoa and oil: In a large mixing bowl, whisk together the 1 cup of unsweetened cocoa powder with 1/2 cup oil until the mixture is smooth and well combined.
- Add butter and sugar: Add the softened 1/2 cup butter to the cocoa and oil mixture, blending until creamy. Then, mix in 1 cup granulated sugar thoroughly.
- Incorporate eggs and vanilla: Add the 4 eggs one at a time, mixing after each addition until just combined. Stir in 1 teaspoon vanilla extract for additional flavor.
- Mix in dry ingredients: Gently fold in 1 cup all-purpose flour and 1/2 teaspoon salt, being careful not to overmix to avoid tough brownies.
- Bake the brownies: Pour the batter evenly into the prepared pan. Bake in the preheated oven for 25-30 minutes, until a toothpick inserted comes out with moist crumbs.
- Add marshmallows topping: Remove the brownies from the oven briefly and evenly sprinkle 2 cups mini marshmallows on top. Return to the oven for an additional 2-3 minutes until marshmallows are puffed and slightly golden.
- Cool the brownies: Let the brownies cool completely in the pan to set properly before frosting.
- Prepare frosting: In a mixing bowl, combine 1/2 cup melted butter, 1/4 cup cocoa powder, 1/4 cup evaporated milk, and 2 cups powdered sugar. Mix until smooth and creamy.
- Adjust frosting consistency: Gradually add the remaining powdered sugar, stirring continuously until you achieve your desired frosting thickness.
- Frost the brownies: Spread the frosting evenly over the cooled marshmallow-topped brownies using a spatula.
- Serve: Cut the brownies into squares and serve. Enjoy the rich, gooey, and decadent Mississippi Mud Brownies!
Notes
- Do not overmix the batter after adding flour to keep brownies tender.
- Use unsalted butter to control the salt level in the brownies.
- Ensure brownies are completely cooled before frosting to prevent melting.
- For a richer flavor, evaporated milk can be substituted with whole milk if desired.
- Brownies can be stored in an airtight container at room temperature for up to 3 days.
