Key Ingredients Explained

• Melted Butter: Using melted butter ensures the brownies are rich and moist. Opt for unsalted butter to control the saltiness.
• Sugar: Granulated sugar sweetens the brownies and helps create that signature chewy texture.
• Unsweetened Cocoa Powder: This is the star ingredient for deep chocolate flavor. Choose high-quality cocoa for the best results.
• Eggs: Lightly beaten eggs bind the ingredients and add richness to the batter.
• Vanilla Extract: A teaspoon of vanilla enhances the chocolate flavor and adds warmth.
• All-Purpose Flour: Provides structure without making the brownies too cakey.
• Toasted Pecans: Toasting the pecans beforehand brings out their nutty flavor and adds a satisfying crunch.
• Miniature Marshmallows: These melt into a gooey layer that’s irresistible.
• Powdered Sugar: Used in the frosting, it creates a smooth, creamy texture.
• Milk and Butter for Frosting: These ingredients ensure the frosting is rich and pourable.

How to Make Mississippi Mud Cake Brownies

Preheat and Prep:

Start by preheating your oven to 350°F. Grease and flour a 15 x 10-inch jellyroll pan to prevent sticking.

Mix the Batter:

In a large bowl, whisk together melted butter, sugar, and cocoa powder until smooth. Add the lightly beaten eggs, vanilla extract, and salt, mixing until fully combined. Stir in the flour and toasted pecans until the batter is thick and homogeneous.

Bake the Brownies:

Pour the batter into the prepared pan, spreading it evenly. Bake for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean.

Add Marshmallows:

Remove the brownies from the oven and immediately sprinkle the miniature marshmallows evenly over the top. Return the pan to the oven for 5 minutes, or until the marshmallows are puffed and golden.

Prepare the Frosting:

While the brownies bake, make the frosting. In a medium bowl, beat powdered sugar, milk, softened butter, and cocoa powder with an electric mixer until smooth and creamy.

Finish and Cool:

Drizzle the frosting over the warm brownies, covering the marshmallow layer completely. Let the brownies cool completely in the pan before cutting into squares.

Pin it

I always use high-quality cocoa powder because it makes a noticeable difference in flavor. My kids can’t get enough of these brownies—they’re a hit at every family gathering.

Perfect Pairings

Serve these brownies with a glass of cold milk or a scoop of vanilla ice cream for an extra indulgent treat. They also pair beautifully with a cup of coffee or espresso to balance the sweetness.

Customize Your Brownies

Nut-Free Option: Skip the pecans or replace them with shredded coconut for a different texture. Extra Chocolate: Add chocolate chips to the batter for even more chocolatey goodness. Spiced Twist: Add a pinch of cinnamon or cayenne pepper to the batter for a unique flavor profile.

Storing and Reheating

Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 2 months. To reheat, microwave individual slices for 10-15 seconds to restore the gooey texture.

These brownies are a labor of love, but every bite is worth it. The combination of fudgy brownies, gooey marshmallows, and creamy frosting is simply irresistible. Whether you’re baking for a crowd or treating yourself, this recipe is a guaranteed winner.
