Unsweetened Cocoa Powder: Choose high-quality cocoa powder for deep chocolate flavor; it sets the foundation for these delectable brownies.
Granulated Sugar: Regular white sugar sweetens the batter perfectly; don’t skimp on this essential ingredient!
Brown Sugar: The molasses in brown sugar adds moisture and chewiness; it’s crucial for achieving that brownie texture.
Eggs: Large eggs provide structure and richness; always use fresh eggs for best results.
All-Purpose Flour: This is your primary dry ingredient; it helps bind everything together without making the brownies too dense.
Butter: Unsalted butter is recommended; melt it to enhance flavors while keeping things rich and moist.
Vanilla Extract: Pure vanilla extract elevates sweetness with its aromatic quality; skip imitation versions if possible.
Mini Marshmallows: These delightful little puffs add irresistible gooeyness; opt for fresh ones for maximum fluffiness.
Chopped Nuts (optional): Walnuts or pecans add crunch and depth; feel free to omit if you’re not a nut fan.
Chocolate Frosting: Use store-bought or homemade frosting to top off your brownies in style; it’s the crowning glory!

How to Make Mississippi Mud Brownies

Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking pan with nonstick spray or butter. This ensures nothing gets stuck during baking.

Make the Brownie Batter: In a large mixing bowl, whisk together granulated sugar, brown sugar, cocoa powder, and melted butter until smooth. The mixture should be shiny and well-combined.

Add Eggs and Vanilla: Crack in the eggs one at a time while mixing thoroughly after each addition. Then stir in vanilla extract until everything is nice and blended.

Sift in Dry Ingredients: Gently fold in all-purpose flour until just combined—be careful not to overmix! You want those fudgy textures without any tough bites.

Add Nuts (if using): If you’re feeling adventurous (or nutty), fold in chopped walnuts or pecans gently into the brownie batter before pouring it into your prepared pan.

Bake Until Set: Pour the batter into your greased pan and spread evenly. Bake for 20-25 minutes or until a toothpick inserted comes out slightly moist but not wet—this ensures fudginess!

Add Toppings: Once baked, remove from oven and immediately sprinkle mini marshmallows over the hot brownies. Return them briefly to the oven just until marshmallows puff up—about 3-5 minutes!

Frosting Glory: Let cool slightly before spreading chocolate frosting generously over marshmallows. Cut into squares once cooled completely—if you can resist the temptation!

With every bite of these Mississippi mud brownies, you’ll savor layers of chocolatey goodness that mix perfectly with fluffy marshmallow clouds. Whether served warm or at room temperature, they’re utterly irresistible! Don’t forget to share… unless you really want them all to yourself!
