Mississippi mud brownies are rich, chocolaty and delicious. With layers of brownie, marshmallows and a chocolate icing it is a fun dessert that is perfect for sharing.
In a large bowl stir together the 1 cup all purpose flour, 1 teaspoon salt, 1 teaspoon baking powder, 1 cup cocoa powder, and 1½ cups granulated sugar.
Add the 1 cup butter, 1 teaspoon vanilla extract and 3 large eggs, Stir to combine. Fold in 1 cup chocolate chips (I used white chips, but your favorite will do.)
Bake for 25-30 minutes.
Top hot brownies with 10 oz. bag marshmallows and return to the oven for 2-3 minutes or until they are puffy. Broil them for a few seconds if you want them to toast slightly.
Allow the brownies and marshmallows to cool.
In a saucepan, melt ½ cup butter over medium heat. Stir in ¼ cup milk and ½ cup cocoa powder.
Remove from heat and stir in 1 teaspoon vanilla extract and 3½ cups powdered sugar.
Drizzle warm chocolate icing over marshmallows and brownies.
Allow to set completely before cutting and serving.
Store leftovers in an airtight container at room temperature for up to 5 days.
