Espresso Brownies with Coffee Frosting Recipe

These frosted espresso brownies are made for coffee lovers: a chewy, fudgy chocolate brownie flavored with espresso and finished with a silky espresso buttercream. Rich chocolate and bright coffee notes pair beautifully in both the brownie and the frosting.

You can enjoy these brownies without the espresso buttercream for a classic shiny-crinkle-topped brownie, but the frosting adds a smooth coffee finish that elevates every bite.

WHY YOU’LL LOVE THEM

Espresso-forward flavor. The instant espresso powder in both the batter and buttercream enhances the chocolate and gives the brownies a deep, aromatic coffee note.

Perfect texture. These brownies are chewy and fudgy with a tender crumb and optional glossy, crinkled top when left unfrosted.

Simple to make. The batter is mixed by hand and comes together quickly. The buttercream requires an electric mixer but is straightforward and forgiving.

Great for coffee lovers. If you love coffee desserts, these frosted espresso brownies are a satisfying, flavor-forward treat.

Step by Step Instructions

Preheat the oven to 350°F (175°C). Line an 8×8 square baking pan with parchment paper so you can lift the brownies out easily once cooled.

BROWNIE BATTER

Chop 4 oz semi-sweet baker’s chocolate and place in a microwave-safe bowl. Melt in the microwave in 20-second intervals, stirring between each session, until fully melted. Set aside to cool slightly.
In a large mixing bowl, whisk together 1/2 cup melted salted butter and 1 cup white sugar until smooth.
Add 2 room-temperature large eggs and 2 teaspoons vanilla extract. Vigorously whisk the mixture for about 5 minutes, until it lightens in color and gains volume—this step helps create the glossy top and tender texture.
Pour the melted chocolate into the egg mixture and whisk until fully combined.
Sift in 3/4 cup all-purpose flour (spooned and leveled), 1/4 cup unsweetened cocoa powder, 1/2 teaspoon salt, and 2 tablespoons instant espresso powder. Fold gently with a rubber spatula just until combined—do not overmix.
Fold in 3/4 cup semi-sweet chocolate chips for pockets of melty chocolate.
Spread the batter evenly into the prepared pan. Bake for about 28 minutes, or until the top is set but the interior remains fudgy. Avoid overbaking to keep the brownies chewy.
Allow the brownies to cool completely in the pan before frosting.

ESPRESSO BUTTERCREAM

In a small cup, stir together 1 tablespoon heavy cream and 1 teaspoon instant espresso powder until the powder dissolves. Set aside.
Using an electric mixer or stand mixer, beat 1/2 cup room-temperature salted butter on high speed for 4 minutes, scraping down the bowl as needed. The butter should become light and creamy.
On medium speed, add 2 cups powdered sugar one cup at a time, mixing briefly after each addition to incorporate and avoid a powdered sugar cloud.
Add the dissolved espresso and heavy cream mixture to the frosting. Increase to high speed and beat for 4–5 minutes until the buttercream is light, fluffy, and spreadable.
Spread the espresso buttercream over the cooled brownies in an even layer. Use a sharp knife, wiping it clean between cuts, to slice into 9 large or up to 16 small brownies.

FREQUENTLY ASKED QUESTIONS

How should I store these brownies?

Store the brownies in an airtight container at room temperature for up to 3 days. If your kitchen is warm, refrigerate and bring to room temperature before serving for the best texture.

What does “spooned and levelled” flour mean?

Spoon the flour into the measuring cup and level it with the back of a knife. Scooping directly with the cup can compact the flour and add extra, which affects texture.

Do the eggs need to be room temperature?

Yes. Room-temperature eggs incorporate more easily and help create the glossy, slightly aerated batter that yields the ideal brownie texture.

Can I skip the frosting?

Absolutely. The brownies are delicious on their own and will have a beautiful shiny top if left unfrosted. The buttercream is optional but adds a rich coffee finish.
