Introduction

Frosted Coffee Brownies are rich, homemade treats with a velvety coffee-flavored frosting that elevates their deliciousness. These brownies combine smooth coffee and deep chocolate flavors, making every bite a delightful experience 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

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

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. This will ensure the brownies don’t stick.
Step 2: Melt the butter in the microwave, then transfer it to a large mixing bowl. Stir in the sugar, eggs, vanilla extract, and coffee extract or instant coffee until fully combined.
Step 3: Gradually add the flour, cocoa powder, salt, and baking powder to the wet ingredients, stirring until the batter is smooth and well combined.
Step 4: 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 5: Allow the brownies to cool completely before frosting.
Step 6: For the frosting, dissolve the instant coffee granules in the heavy whipping cream and set aside.
Step 7: In a separate bowl, beat the unsalted butter until light and fluffy. Gradually add the powdered sugar, mixing until fully incorporated.
Step 8: Slowly pour in 2 tablespoons of the coffee-infused cream and mix until the frosting reaches a smooth, spreadable consistency. Add more cream if needed, one tablespoon at a time.
Step 9: Generously spread the frosting over the cooled brownies. Slice and serve to enjoy!

Tips & Variations

Use espresso powder instead of instant coffee granules for a stronger coffee flavor without overpowering the chocolate.
Start with 2 tablespoons of heavy cream in the frosting and add more as needed to reach your desired consistency.
For added texture, fold chocolate chips or chopped nuts into the brownie batter before baking.

Storage

Store frosted brownies in an airtight container at room temperature for up to 3 days. To keep them fresh longer, refrigerate for up to one week. For freezing, wrap individual unfrosted brownies tightly in plastic wrap and place them in an airtight container or freezer bag; they will keep for up to 3 months. Thaw at room temperature before frosting or gently microwave for a quick treat.

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 a separate bowl, whisk together the cocoa powder, flour, salt, and baking powder. Gently fold the dry ingredients into the wet just until combined to avoid dense, tough brownies.

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

Yes, espresso powder works well and provides a bolder coffee taste. Start with the same amount as instant coffee and adjust to your preference for a stronger or milder flavor.

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

Yes, a 9-inch pan can be used, but the brownies will be thinner and may bake faster. Check for doneness a few minutes early by testing with a toothpick; a few moist crumbs indicate they are ready.

Do frosted coffee brownies freeze well?

The brownies freeze well without frosting. Frosting may change texture after thawing, so freeze brownies unfrosted, then prepare and spread frosting fresh after thawing for best results.
