• Try swapping mini marshmallows for peanut butter chips for a nutty twist.
• Let the marshmallows brown slightly under the broiler for a toasted flavor, but watch carefully to prevent burning.

FAQs

Can I use regular milk instead of evaporated milk for the frosting?

You can substitute regular milk, but evaporated milk gives the frosting a richer and creamier texture, which enhances the flavor.

How do I prevent the brownies from drying out?

Be careful not to overbake the brownies and keep the pan covered or in an airtight container once cooled to maintain moisture.

Ingredients

Scale 1x2x3x

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
• 1 teaspoon vanilla extract
• 3 cups powdered sugar

Instructions

1. Preheat 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 do not stick.
2. Combine Oil and Cocoa Powder: In a large mixing bowl, whisk together the oil and 1 cup of unsweetened cocoa powder until the mixture is smooth and well combined, forming a rich chocolate base for the brownies.
3. Add Butter and Sugar: Add the softened butter to the cocoa mixture and blend until creamy. Then stir in the granulated sugar to help create a delicious crust on your brownies.
4. Incorporate Eggs and Vanilla: Add the eggs one at a time into the mixture, beating well after each addition to ensure a smooth batter. Stir in the vanilla extract to enhance the chocolate flavor.
5. Mix in Dry Ingredients: Gently fold in the all-purpose flour and salt, being careful not to overmix to keep the brownies tender and moist.
6. Bake the Brownies: Pour the batter evenly into the prepared pan and bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
7. Add Marshmallows: Remove the pan from the oven and evenly sprinkle 2 cups of mini marshmallows over the warm brownies. Return to the oven for an additional 2 to 3 minutes, just until the marshmallows begin to melt and become gooey.
8. Cool Completely: Allow the brownies to cool entirely in the pan; this helps the marshmallow layer to set and makes frosting easier to spread.
9. Prepare Frosting: In a bowl, mix together the melted butter, 1/4 cup unsweetened cocoa powder, evaporated milk, and 2 cups of powdered sugar until smooth and creamy.
10. Adjust Frosting Consistency: Gradually add the remaining powdered sugar, stirring continually until the frosting reaches your desired thickness and consistency.
11. Frost the Brownies: Spread the prepared frosting evenly over the cooled brownies to create a decadent, chocolatey topping.
12. Serve: Cut the brownies into squares and serve. Enjoy your ultimate Mississippi mud brownies that perfectly combine fudgy chocolate with marshmallow gooeyness and rich frosting.

Notes

• Make sure not to overmix the batter after adding flour to keep brownies tender.
• Use unsalted butter to better control the saltiness of the dessert.
