Introduction

Frosted Coffee Brownies are rich, homemade treats topped with a velvety coffee-flavored frosting that takes their deliciousness to the next level. Combining smooth coffee with deep chocolate flavors, these brownies are perfect for satisfying your sweet tooth with a subtle caffeine kick.

Three square pieces of dark brown chocolate cake with a thick, smooth layer of light beige frosting on top are placed closely on a round white plate. The dense cake base has a slightly crumbly texture while the creamy frosting is evenly spread with soft swirls and peaks. The plate rests on a white marbled surface with a soft cloth nearby. The overall look is simple and inviting. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1/2 cup all-purpose flour
2 large eggs
1/3 cup unsweetened cocoa powder
1 teaspoon vanilla extract
1 stick unsalted butter
2 teaspoons coffee extract or 1 tablespoon instant coffee
1 cup granulated sugar
1/4 teaspoon baking powder
1/4 teaspoon salt
For the Coffee Frosting:
1/3 cup unsalted butter
2 cups powdered sugar
1 1/2 teaspoons instant coffee granules
2-4 tablespoons heavy whipping cream

Instructions

Step 1: Preheat your oven to 350°F (175°C) and prepare an 8-inch baking dish by coating it with non-stick spray or lining it with parchment paper followed by a light spray.
Step 2: Melt the butter in a microwave-safe bowl, then transfer it to a large mixing bowl.
Step 3: Add the granulated sugar, eggs, vanilla extract, and coffee extract (or instant coffee) to the melted butter. Stir until fully blended.
Step 4: Gradually add the all-purpose flour, unsweetened cocoa powder, salt, and baking powder. Mix until the batter is smooth and well combined.
Step 5: Pour the batter evenly into the prepared baking dish and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Step 6: Allow the brownies to cool completely before frosting.
Step 7: To make the frosting, dissolve the instant coffee granules in 2 tablespoons of heavy whipping cream and set aside.
Step 8: Beat the unsalted butter in a separate bowl until light and fluffy. Gradually add the powdered sugar while continuing to beat.
Step 9: Slowly pour in the coffee-infused cream and mix well. Add more cream, a tablespoon at a time, until the frosting reaches your desired consistency.
Step 10: Spread the frosting generously over the cooled brownies, slice, and enjoy!

Tips & Variations

Use espresso powder instead of instant coffee to boost the coffee flavor without overpowering the chocolate.
For a lighter frosting, start with 2 tablespoons of cream and add more gradually to reach your preferred texture.
Fold in chocolate chips or chopped nuts into the brownie batter before baking for added texture and richness.

Storage

Store frosted coffee brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. To freeze, wrap individual brownies tightly in plastic wrap and place them in a freezer-safe container or bag. They keep well for up to 3 months frozen. Thaw at room temperature or microwave for a quick treat. For best frosting texture, freeze brownies unfrosted and add frosting fresh after thawing.

How to Serve

The cookie's surface is dark brown with a rough, crackled texture, studded with visible pieces of chopped nuts and coconut flakes that add a mix of light beige and tan colors against the chocolate. The cookie sits on a black cooling rack over a white marbled texture. Other similar cookies are partially visible around it. photo taken with an iphone --ar 4:5 --v 7

FAQs

How do I mix the brownie batter so it turns out right?

Start by combining the melted butter, sugar, eggs, vanilla, and coffee until smooth. In a separate bowl, whisk together the cocoa powder, flour, salt, and baking powder. Gently stir the dry ingredients into the wet mixture just until no flour streaks remain. Avoid overmixing to prevent dense brownies.

Can I use espresso powder instead of instant coffee or coffee extract?

Yes, espresso powder works well and offers a stronger coffee flavor. Use the same amount as instant coffee or adjust to taste—less for a milder flavor, more for boldness.

Can I bake these brownies in a 9-inch pan instead of 8-inch?

Yes, but the brownies will be thinner and may bake faster. Start checking for doneness a few minutes early, looking for set edges and a glossy, just-set center.

Do frosted coffee brownies freeze well?

The brownie base freezes well, but frosting may change texture when thawed. For best results, freeze the brownies without frosting, thaw, then frost fresh before serving.
