My favorite food is marshmallows so it’s no surprise that I love these Mississippi Mud Brownies.
The brownies are unbelievably fudgy and the marshmallowy chocolate frosting totally has my heart.
Key to Success #1 – Use Melted Butter in the Brownies
You don’t need to get out your mixer for these brownies.
You can whip these up using just one microwave-safe bowl and a sturdy spoon.
Start off by melting your butter in the microwave then stir in the unsweetened cocoa powder.
Once it’s smooth, stir in the sugar then add the beaten eggs and vanilla.
Gently stir in the dry ingredients.
Note that this brownie recipe does not call for baking powder or baking soda. This allows the brownies to bake up thick and fudgy and not fluffy and cake-like.
Key to Success #2 – Watch the Cook Time Carefully
Since these brownies are so fudgy, you’ll have to watch them carefully in the oven so that they don’t over-bake and turn hard around the edges.
Test the brownies by inserting a toothpick into the center of the brownies.
If the toothpick is wet, cook the brownies for another 5 minutes.
If the toothpick has a few moist crumbs on it, your brownies are ready.
These are the red Kate Spade plates that I used with my brownies.
Key to Success #3 – Frost Brownies as Soon as They Come Out of the Oven
During the last few minutes that your brownies are baking, make your chocolate frosting.
Use an electric mixer to whip up the softened butter, cocoa powder, and vanilla extract.
Then slowly add in the powdered sugar and milk.
When the brownies come out of the oven, stir the miniature marshmallows into the frosting then spread it onto the warm brownies.
The heat from the brownies will help the frosting seep into the brownies, making them extra moist and delicious.
Spread the frosting over the warm brownies then let them cool completely before cutting them into squares.
They need time to really bring the flavors together. Don’t be tempted to dig into them before they’re cool.
They are worth the wait!
