Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Unsalted butter – Melted butter gives the brownies their rich, fudgy texture. Using real butter makes a noticeable difference in flavor and mouthfeel.

Granulated sugar – Sweetens the batter and creates a slightly crackly top as it bakes.

Brown sugar – Adds moisture and a subtle caramel undertone that enhances the chocolate flavor.

Eggs – Bind the ingredients and provide structure while keeping the brownies soft and chewy.

All-purpose flour – Just enough to hold the brownies together without making them cakey.

Cocoa powder – The foundation of any great brownie. Use high-quality unsweetened cocoa for a deep chocolate taste.

Instant coffee or espresso powder – Dissolved in a little hot water, it amplifies the chocolate flavor and adds a hint of bitterness that balances the sweetness.

Salt – Brings out the richness of both the cocoa and the coffee.

Vanilla extract – Adds warmth and rounds out the flavors beautifully.

Chocolate chips (optional) – Fold in for extra gooey pockets of chocolate.

For the Coffee Frosting

Powdered sugar – Forms the base of the frosting and gives it a smooth, creamy texture.

Butter – Adds richness and helps create a fluffy consistency.

Strong brewed coffee or espresso – Infuses the frosting with bold coffee flavor and gives it that lovely mocha aroma.

Cocoa powder (optional) – For a deeper chocolate-coffee frosting, mix a tablespoon into the icing.

Vanilla extract – Ties the flavors together with a subtle sweetness.

Directions

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper and lightly grease it.

In a medium saucepan, melt the butter over low heat. Remove from the heat and whisk in granulated sugar and brown sugar until combined. Allow to cool slightly, then whisk in the eggs one at a time, followed by vanilla extract.

In a separate bowl, mix together the flour, cocoa powder, salt, and instant coffee. Gradually fold the dry ingredients into the wet mixture until just combined — do not overmix. If using, fold in the chocolate chips.

Pour the batter into the prepared pan and smooth the top. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Let the brownies cool completely before frosting.

To make the frosting, beat the softened butter until creamy. Gradually add powdered sugar, alternating with small amounts of brewed coffee, until you reach a smooth, spreadable consistency. Mix in vanilla extract and cocoa powder (if using). Spread the frosting evenly over the cooled brownies.

Chill for 20 minutes to help the frosting set before slicing into squares. Serve at room temperature for the best flavor and texture.
