Chocolate Brownies with Chocolate Frosting

Warm, fudgy, and deeply chocolatey, these Chocolate Brownies with Chocolate Frosting are the kind of treat that makes any day feel special. The brownies bake up with a slightly crackly top and a dense, moist interior that melts on the tongue. The frosting is silky and rich, adding a smooth chocolate finish that balances the brownie base without making it overly sweet. You will notice warm cocoa aroma as they bake and the scent of butter and chocolate when the frosting is mixed. These brownies are ideal for after-dinner dessert, potlucks, school bake sales, or anytime you need a portable, crowd pleasing chocolate fix.

Ingredients

1/2 cup unsalted butter, cut into smaller pieces
Provides richness and helps melt the chocolate smoothly.
2 (4-ounce) semi-sweet chocolate bars, coarsely chopped
Uses solid chocolate for a glossy, fudgy base when melted with the butter.
3/4 cup granulated sugar
Adds sweetness and helps create a slightly crisp top.
1/4 cup packed light or dark brown sugar
Adds moisture and a subtle caramel note. Dark brown gives deeper flavor.
3 large eggs
Bind the batter and add structure while keeping the brownies tender.
1 teaspoon pure vanilla extract
Brightens and rounds the chocolate flavor.
2/3 cup all-purpose flour
Provides the structure for the brownies without making them cakey.
2 tablespoons unsweetened cocoa powder
Intensifies the chocolate flavor and deepens color.
1/4 teaspoon salt
Balances sweetness and enhances chocolate taste.
1 cup semi-sweet chocolate chips
Adds pockets of melted chocolate throughout the brownies.

Frosting ingredients

1/2 cup unsalted butter, softened
Creates a creamy base for the frosting.
1 and 1/2 cups confectioners’ sugar
Sweetens and thickens the frosting to a spreadable texture.
1/3 cup unsweetened cocoa powder
Provides chocolate depth and balances the sugar.
3 tablespoons heavy cream or milk, slightly warm
Thins the frosting to a silky consistency. Use the cream for richer flavor or milk if you prefer.
1/2 teaspoon pure vanilla extract
Rounds the frosting flavor.
Pinch of salt
Keeps the frosting from tasting flat and enhances the chocolate.

Step-by-step Instructions

Make the melted chocolate base. In a heatproof bowl, combine the cut 1/2 cup unsalted butter and the coarsely chopped 2 (4-ounce) semi-sweet chocolate bars. Melt in the microwave in 20-second increments, stirring between intervals, or melt gently over low heat on the stove. Stir until smooth, then let it cool for 5 minutes. Tip: If using the microwave, stop as soon as a few small pieces remain and stir, they will melt from residual heat.
Prepare the pan and oven. Preheat the oven to 350°F (177°C). Line a 9-inch square baking pan with parchment paper, leaving an overhang to lift the brownies out when cool.
Add the sugars. Whisk the 3/4 cup granulated sugar and 1/4 cup packed brown sugar into the cooled chocolate and butter mixture until well combined and slightly glossy.
Mix in eggs and vanilla. Add the 3 large eggs and 1 teaspoon pure vanilla extract, mixing until fully incorporated and the batter looks uniform.
Combine dry ingredients. In a separate bowl, whisk together the 2/3 cup all-purpose flour, 2 tablespoons unsweetened cocoa powder, and 1/4 teaspoon salt.
Fold dry into wet. Gradually fold the dry mixture into the wet chocolate mixture until no streaks of flour remain. Do not overmix to keep the brownies tender.
Add chips and bake. Gently fold in the 1 cup semi-sweet chocolate chips, then spread the batter evenly in the prepared baking pan. Bake for 32 to 35 minutes, or until the top appears set and a toothpick inserted near the center comes out with a few moist crumbs. Tip: Start checking at 30 minutes to avoid overbaking; fudgy brownies set as they cool.
Cool completely. Remove the pan from the oven and place on a wire rack. Let the brownies cool completely in the pan before frosting.
Make the frosting. In a mixing bowl, beat the 1/2 cup softened unsalted butter until creamy. Add the 1 and 1/2 cups confectioners’ sugar, 1/3 cup unsweetened cocoa powder, 3 tablespoons slightly warm heavy cream or milk, 1/2 teaspoon pure vanilla extract, and a pinch of salt. Beat until smooth and well combined. If the frosting is too thick, add a little more warm milk or cream, 1/2 teaspoon at a time.
Frost and serve. Once the brownies are completely cooled, spread the frosting evenly over the top. Use the parchment overhang to lift the brownies from the pan, cut into squares, and serve.

Tips, Storage & Variations

Tip: Let the brownies cool completely before frosting to prevent the frosting from melting.
Tip: For cleaner slices, chill the frosted brownies 20 minutes, then cut with a sharp knife warmed under hot water and wiped dry between cuts.
Storage: Unfrosted brownies last up to 1 week at room temperature in an airtight container. Frosted brownies last 2 days at room temperature or up to 1 week refrigerated.
Freezing: Wrap individual unfrosted or frosted squares tightly and freeze for up to 3 months. Thaw overnight in the refrigerator.
Flavor variations using only the ingredients on hand: fold extra semi-sweet chocolate chips into the batter for chunkier brownies, or sprinkle a few chips on top of the frosting while it is still soft. Use dark brown sugar instead of light for a deeper molasses note. Substitute warm milk for the heavy cream in the frosting to lighten the texture.

How do I know when brownies are done?
The top should look set and slightly crackly. A toothpick inserted into the center should come out with a few moist crumbs, not wet batter.
Can I use milk instead of heavy cream in the frosting?

Can I make the brownies ahead of time?
Yes, you can bake them a day ahead, cool, frost, and store as directed under Storage.
Why did my brownies turn out cakey?
Overmixing after adding flour or using too much flour can make brownies cakey. Fold gently and measure flour accurately.

Yes, semi-sweet is recommended, but you can use other semi-sweet varieties you have on hand.
