You’ll need:
For The Brownie Base:
- 2 cups of all-purpose flour, spooned and leveled
- ½ cup of unsweetened Dutch cocoa powder
- ½ teaspoon of kosher salt
- 1 cup of salted sweet cream butter, melted
- 2 cups of granulated sugar
- 3 tablespoons of pure vanilla extract
- 4 large eggs, room temperature and beaten
- 4 cups of miniature marshmallows
For The Chocolate Frosting:
- ½ cup of salted sweet cream butter, melted
- ⅓ cup of unsweetened Dutch cocoa powder
- ¼ cup + 2 tablespoons of half and half, room temperature
- 1 tablespoon of pure vanilla extract
- 3⅔ cups of powdered sugar, sifted
Substitutions And Additions
NUTS: You can add chopped nuts to these fudgy brownies to turn them into rocky road brownies.
CHOCOLATE CHIPS: You can also add 1 to 2 cups of milk chocolate or semi-sweet chocolate chips to the brownie batter. Toss the chocolate chips in 1 tablespoon of all-purpose flour before adding to the fudgy chocolate brownie batter.
COCOA POWDER: You can substitute plain unsweetened cocoa powder or even unsweetened dark cocoa powder for Dutch-processed cocoa powder.
How To Make This Marshmallow Brownies Recipe
The delicious, chewy texture of brownies is classic and this brownie recipe is no different. Once you add the marshmallows and frosting, they will be over-the-top delicious.
STEP ONE: Preheat the oven to 350°F. Line a 9×13 baking dish with parchment paper. Be sure to leave about an inch of parchment paper above the edges overhanging. Lightly spray the parchment paper with nonstick cooking spray.
OUR RECIPE DEVELOPER SAYS
The overhanging parchment paper will help you to lift out the entire rectangle of brownies so that you can cut them into small squares easier.
STEP TWO: Add the flour, unsweetened cocoa powder, and salt to a medium bowl. Whisk to combine.
STEP THREE: Add the melted butter, granulated sugar, and vanilla extract to a large mixing bowl. Whisk to combine.
STEP FOUR: Whisk in the beaten eggs.
STEP FIVE: Stir the flour mixture into the wet ingredients. Stir just until incorporated. Be sure not to overmix.
PRO TIP:
Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to check your brownies at the lower end of the recommended baking time.
STEP SIX: Evenly spread the brownie batter in the prepared baking dish. Bake for 25 to 28 minutes, or until a toothpick inserted comes away somewhat clean with just a few crumbs.
PRO TIP:
It is important not to overbake the brownies, or they will come out of the oven dense and tough.
STEP SEVEN: Remove the brownies from the oven. Evenly sprinkle the miniature marshmallows over the top of the brownie layer.
STEP EIGHT: Add the melted butter, unsweetened cocoa powder, half and half, and vanilla to a medium-sized mixing bowl. Whisk until smooth.
STEP NINE: Add the sifted powdered sugar 1 cup at a time, whisking well after each addition until smooth. Evenly spread the chocolate buttercream frosting over top of the marshmallow layer. Cover and chill in the refrigerator for 2 hours.
STEP TEN: Just before serving, lift the brownies out of the pan using the parchment paper. Slice the brownies with a sharp knife into 3 slices x 5 slices (15 slices).
How To Serve
Marshmallow brownies are a delicious treat and can be served in a variety of ways.
Although they can easily be enjoyed on their own, for a more decadent dessert, pair them with vanilla ice cream, caramel sauce, hot fudge sauce, or whipped cream.
