Introduction

Frosted Coffee Brownies are rich, homemade treats with a velvety coffee-flavored frosting that elevates their deliciousness. These brownies combine smooth coffee and chocolate flavors in every bite, making them a perfect dessert for chocolate and coffee lovers alike.

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

For the Brownies:

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 and spraying lightly.
Step 2: Melt the butter in the microwave. Once melted, transfer it to a large mixing bowl.
Step 3: Add the granulated sugar, eggs, vanilla extract, and coffee extract (or instant coffee) to the butter. Stir until everything is thoroughly blended.
Step 4: In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder. Gradually add these dry ingredients to the wet mixture, stirring until the batter is smooth and fully combined.
Step 5: Spread 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 applying the frosting.
Step 7: To make the frosting, dissolve the instant coffee granules in the 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, mixing until fully combined.
Step 9: Slowly pour in 2 tablespoons of the coffee-infused cream and mix until well combined. Add more cream, 1 tablespoon at a time, until the frosting reaches your preferred consistency.
Step 10: Spread the frosting generously over the cooled brownies. Slice and serve.

Tips & Variations

Use espresso powder instead of instant coffee granules to enhance the coffee flavor with a richer depth.
Start with 2 tablespoons of cream for a lighter frosting and add more gradually to adjust consistency.
Fold 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. For longer freshness, refrigerate for up to one week. To freeze, wrap individual unfrosted brownies tightly in plastic wrap, place in an airtight container or freezer bag, and freeze for up to 3 months. Thaw at room temperature or microwave briefly before frosting and serving.

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?

Combine melted butter, sugar, eggs, vanilla, and coffee extract or instant coffee until smooth. In another bowl, whisk the flour, cocoa powder, salt, and baking powder, then gently fold this into the wet ingredients just until no streaks of flour remain. Avoid overmixing to keep the brownies tender and fudgy.

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

Yes, espresso powder works well and provides a stronger coffee flavor. Use about the same amount as instant coffee, or slightly less if you prefer a milder taste. Adjust to your preference in future batches.

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

You can use a 9-inch pan, but the brownies will be thinner and may bake faster. Begin checking for doneness a few minutes earlier than the recommended time. Look for set edges and a center that is glossy but not wet, with a toothpick coming out with a few moist crumbs.

Do frosted coffee brownies freeze well?

The brownies freeze well, but the frosting may change texture after thawing. For best results, freeze the brownies unfrosted, then prepare and add the coffee frosting fresh after thawing.
