Easy Mississippi Mud Brownies Recipe
Easy Mississippi Mud Brownies Recipe (Marshmallow Brownies) have a soft brownie bottom, gooey marshmallows, and an irresistible chocolate frosting on top.
Ingredients
Brownies
- 1 box brownies, plus ingredients on back of box
- 2 ½ cups mini marshmallows
Chocolate frosting
- ½ cups (1 stick) unsalted butter, melted
- ⅓ cup cocoa powder
- ⅓ cup evaporated milk
- 1 teaspoon vanilla extract
- 3 - 3 ½ cups powdered sugar
Instructions
Brownies
- Preheat oven to 350 degrees. Prepare a 9x13" baking dish with nonstick spray. Make and bake brownies, based on box directions or until a toothpick tested in the center comes out clean.
- Remove brownies from the oven and place marshmallows over the top.
- Place back into the oven for 2-3 minutes or until they start to puff. Remove from oven and cool completely.
Chocolate Frosting
- Once cooled, start making the frosting. In a large bowl, beat melted butter, cocoa, milk, and vanilla extract with 2 cups of powdered sugar.
- Pour in the rest of the powdered sugar, mix until the frosting is smooth. It will be light and fluffy, with no lumps.
- Spread the frosting over the marshmallows once they have completely cooled. It should smoothly spread.
- If you can let them set overnight, it will make them easier to cut. Cut with a plastic knife, knife dipped into hot water, or a knife sprayed with cooking spray. Enjoy!
Notes
- Variations: Frost the brownies and then place the marshmallows on top and brown with a kitchen torch.
- You can also add chocolate chips in with the brownie mix, before baking.
