How to Prepare Mississippi Mud Brownies
Now that you’ve got all your ingredients lined up, let’s dive into the fun part: making these delightful Mississippi Mud Brownies! Follow these steps to ensure you get that rich, chocolatey goodness every time.
Step 1: Preheat and Prepare
First things first, preheat your oven to 350°F (175°C). This is super important because you want the brownies to bake evenly. While that’s heating up, grab a 9×13-inch baking pan and give it a good spritz with non-stick spray. This little step helps the brownies come out perfectly without any sticking. Trust me, you’ll thank yourself later when it’s time to cut them!
Step 2: Mix the Base
In a large bowl, pour your vegetable or canola oil over the cocoa powder. Give it a good mix until it’s well combined. Next, add in your softened butter and stir until it’s all nice and smooth. You want this mixture to be completely blended, so take your time! Then, toss in the granulated sugar and mix it for about a minute. You’re looking for a glossy, thick base that screams chocolate heaven!
Step 3: Incorporate Eggs and Flavor
Now it’s time to bring in the eggs! Add them one at a time, stirring well after each addition. This step is crucial for achieving that perfect brownie texture. After you’ve mixed in the last egg, stir in the alcohol-free vanilla flavoring. The aroma will be amazing, and it’ll elevate the chocolate flavor beautifully!
Step 4: Add Dry Ingredients
Next up, it’s time to incorporate the flour and salt. Gently fold them into your mixture until just combined. Here’s the key: don’t overmix! You want a few flour streaks to remain visible; that means your brownies will be fudgy and soft rather than dense and chewy.
Step 5: Bake the Brownies
Pour that luscious brownie batter into your prepared pan and spread it evenly. Pop it in the oven and let it bake for 25–30 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with just a few moist crumbs. Keep a close eye on them because overbaking can lead to dry brownies, and we definitely don’t want that!
Step 6: Add Marshmallows
Here comes the fun part! As soon as you pull those brownies out of the oven, sprinkle the mini marshmallows evenly over the top. They’ll start to melt and puff up, creating that gooey topping we all love. Pop them back in the oven for just 2–3 minutes until they’re perfectly puffed and soft. You’ll want to keep an eye on them so they don’t turn into a marshmallow disaster!
Step 7: Cool and Frost
Once the marshmallows are all puffed and perfect, let the brownies cool completely in the pan. Patience is key here! While they cool, you can whip up your frosting. In a mixing bowl, stir together the melted butter, cocoa powder, evaporated milk, vanilla flavoring, and 2 cups of powdered sugar. Beat until it’s smooth and creamy. If you want a thicker frosting, gradually add the remaining powdered sugar until you reach your desired consistency. Once the brownies are cool, spread that luscious frosting evenly over the top, and then it’s time to cut them into squares!

Tips for Success with Mississippi Mud Brownies
To ensure that your Mississippi Mud Brownies turn out absolutely perfect every time, here are some helpful tips I’ve picked up along the way:
- Use a Plastic Knife for Cutting: When it’s time to slice the brownies, reach for a plastic knife! It glides through the marshmallows and frosting without tearing them apart, giving you those clean, beautiful squares.
- Make the Frosting Ahead of Time: If you’re planning to serve these brownies for a special occasion, consider making the frosting a day or two in advance. Store it in an airtight container in the fridge, and it will be ready to spread when you are!
- Don’t Overmix the Batter: Remember, overmixing can lead to tough brownies. Mix until just combined, and you’ll be rewarded with that fudgy, melt-in-your-mouth texture we all crave!
- Let Them Cool Completely: I know it’s tempting to dive in right away, but letting the brownies cool completely before frosting is crucial. This ensures the frosting sets nicely on top without sliding off.
- Experiment with Toppings: Feel free to get creative with your toppings! Chopped nuts, chocolate chips, or even a drizzle of caramel can take these brownies to the next level. Just sprinkle them on after the marshmallows puff up!
- Check for Doneness Carefully: Ovens can vary, so start checking your brownies a few minutes before the suggested baking time. You want them to be just set in the center—no one likes a dry brownie!
- Store Properly: If you have leftovers (though I doubt it!), store them in an airtight container at room temperature for up to 3 days. You can also freeze them for longer storage—just make sure to wrap them well!
With these tips, you’ll be well on your way to making the best Mississippi Mud Brownies ever. Happy baking!

FAQ About Mississippi Mud Brownies
Can I use different types of cocoa powder?
Absolutely! You can use either natural cocoa powder or Dutch-processed cocoa powder in this recipe. Natural cocoa powder is more acidic and has a stronger chocolate flavor, while Dutch-processed cocoa powder is treated to neutralize acidity and gives a smoother, richer taste. If you choose to go with Dutch cocoa, just make sure to adjust for the leavening agents, as it works best with baking powder rather than baking soda. Either way, you’ll end up with delicious brownies!
How do I store leftovers?
If you happen to have any leftovers (which is rare!), you can store your Mississippi Mud Brownies in an airtight container at room temperature for up to 3 days. This keeps them nice and fudgy! If you want to save them for longer, feel free to freeze them. Just wrap them well in plastic wrap or aluminum foil, and they’ll keep for up to 3 months. Thaw at room temperature before enjoying again—if you can wait that long!
Can I make these brownies gluten-free?
Yes, you can make these brownies gluten-free quite easily! Just swap out the all-purpose flour for a 1:1 gluten-free flour blend. Make sure the blend contains xanthan gum, which helps mimic the structure that gluten provides. Keep in mind that the texture might be slightly different, but they’ll still be incredibly delicious and gooey!
What can I serve with Mississippi Mud Brownies?
The options are endless! For a classic pairing, serve these brownies warm with a scoop of vanilla ice cream—there’s something magical about that chocolatey goodness melting into the ice cream. You could also drizzle some hot fudge or caramel sauce on top for an extra indulgent treat. Whipped cream is a great option too, adding a lightness that balances the brownies’ richness. Get creative and make it your own!
Variations of Mississippi Mud Brownies
One of the best things about Mississippi Mud Brownies is how versatile they are! You can easily tweak the recipe to suit your taste buds or to impress your friends. Here are some fun variations to consider:
- Add Nuts: If you enjoy a bit of crunch, toss in 1 cup of chopped nuts like walnuts or pecans into the brownie batter. This not only adds texture but also brings a delightful nutty flavor that pairs beautifully with the chocolate.
- Swirl in Peanut Butter: For a nutty twist, try swirling in some creamy or chunky peanut butter into the brownie batter before baking. Just drop spoonfuls of peanut butter and gently swirl it with a knife for a marbled effect. The rich peanut flavor complements the chocolate perfectly!
- Top with Chocolate Chips: Before adding the marshmallows, sprinkle a handful of semi-sweet or dark chocolate chips over the brownie batter. This extra layer of chocolatey goodness will make each bite even more decadent.
- Change the Toppings: Instead of marshmallows, consider using toasted coconut flakes or crushed Oreos on top of the brownies. These toppings give a different flavor profile and a fun twist to the classic recipe.
- Drizzle with Caramel: A drizzle of warm caramel sauce over the frosted brownies can take them to a whole new level. The sweet, buttery caramel contrasts beautifully with the rich chocolate.
- Use Different Frosting: While the chocolate frosting is heavenly, you can try a cream cheese frosting for a tangy twist. Just beat together cream cheese, powdered sugar, and a little vanilla for a deliciously different topping.
- Experiment with Extracts: Switch up the flavor by adding some almond extract or mint extract to the brownie batter. These flavors will introduce an exciting twist that can be surprisingly delightful!
Feel free to mix and match these ideas! Each variation can impact the flavor and texture of your Mississippi Mud Brownies, making it a fun adventure every time you bake. The possibilities are endless, so get creative and make this recipe your own!
