Key ingredients for hot chocolate brownies with marshmallow frosting
Unsalted butter (1 cup)
Butter keeps the brownie base moist and tender. Using unsalted lets you control the salt, which keeps the chocolate flavor in front.
Dark chocolate chips (1 cup)
The chips give the brownies their deep chocolate flavor. They melt smoothly into the batter and make the texture fudgy.
Granulated sugar (2 cups)
Sugar sweetens the brownies and makes them chewy. It also forms the thin, crisp top crust over the soft middle.
Eggs (4 large)
Eggs bind the batter and add moisture. They also keep the brownies from turning too dense.
Vanilla extract (1 teaspoon)
Vanilla adds a warm, aromatic note that rounds out the chocolate.
All-purpose flour (1 cup)
Flour holds the brownies together without making them cakey.
Cocoa powder (1 cup)
Cocoa deepens the chocolate flavor and gives the brownies their dark color.
Baking powder (1 teaspoon)
A little baking powder lets the brownies rise slightly so they are lighter.
Salt (1/2 teaspoon)
Salt balances the sugar and makes the chocolate taste richer.
Mini marshmallows (2 cups)
The marshmallows go on top, where they melt into a soft, fluffy layer that contrasts with the fudgy brownie.
Powdered sugar (1 cup)
Powdered sugar is the base of the marshmallow frosting. It makes the frosting smooth and gives it a consistency you can drizzle.
Milk (1/4 cup)
Milk makes the frosting creamy and loose enough to drizzle, and it brings the frosting ingredients together.

Variations of hot chocolate brownies with marshmallow frosting
Add some crunch
Fold walnuts or pecans into the batter for crunch against the fudgy middle.
Flavor infusions
Add a teaspoon of instant coffee granules to the batter for a mocha version, or swap the vanilla extract for almond extract.
Alternative frostings
Chocolate ganache or cream cheese frosting can replace the marshmallow frosting.
Seasonal variations
In the fall, a pinch of cinnamon or pumpkin spice adds warmth. In summer, top the brownies with fresh berries.

Cooking tips and notes
Melting chocolate and butter
Melt the dark chocolate chips and butter together gently over medium heat, stirring the whole time so the chocolate doesn’t seize. Let the mixture cool slightly before you add the sugar and eggs, and the batter will stay smooth.
Testing for doneness
Insert a toothpick in the center. A few moist crumbs mean the brownies are fudgy and not overbaked. They keep firming up as they cool.
Frosting tips
Whisk the powdered sugar and milk until completely smooth. For a thicker frosting, add more powdered sugar a little at a time. Drizzle it over the brownies while they are warm so it melts in slightly.
Serving suggestions for hot chocolate brownies with marshmallow frosting
Pair with ice cream
Serve the brownies warm with a scoop of vanilla or mint ice cream. The cold ice cream melts into the warm brownie.
Drizzle with caramel
Caramel sauce drizzled over the top just before serving adds a buttery flavor that goes with both the chocolate and the marshmallow.
Add fresh berries
Fresh raspberries or strawberries add color, and their tartness cuts the sweetness.
