The creamy coffee frosting on top takes them right over the edge. Every time I make these for a gathering or just a quiet night in, people cannot stop reaching for a second piece.

The first time I baked these, I was surprised at how perfectly the coffee brought out the chocolate. Now my sister begs me to bring a batch every holiday.
Ingredients
- Unsalted butter: Adds richness and fudgy texture Look for high-fat content butter for the best results
- Granulated sugar: Sweetens and helps create that crackly brownie top Choose fine sugar so it dissolves easily
- Large eggs: Bind the brownies together Use the freshest eggs you can for fluffier results
- Vanilla extract: Enhances the sweetness and adds a subtle warmth Pick pure vanilla for the richest background flavor
- Coffee extract or instant coffee: Intensifies the chocolate flavor and brings coffee notes Dissolve instant coffee in a splash of water for no clumping
- Unsweetened cocoa powder: Deep chocolate taste Dutch process cocoa gives a smoother flavor if you have it
- All-purpose flour: Structure and chew Opt for unbleached flour so the cocoa shines
- Salt: Balances sweetness and sharpens chocolate flavor Use fine salt for even distribution
- Baking powder: Just a little for a touch of lift Check it's fresh for proper rise
- Instant coffee granules: For the frosting's bold flavor Use a robust blend if you want a pronounced coffee taste
- Heavy whipping cream: Makes frosting luscious and smooth Only add as much as needed for spreadable texture
- Powdered sugar: Sweetness and creamy body Sift to avoid lumps in the frosting
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to three hundred fifty degrees Fahrenheit and prepare an eight-inch square pan with nonstick spray or line it with parchment so removal is effortless
- Melt the Butter:
- Place butter in a microwave safe bowl and heat in short bursts until melted Stir and let cool for a few minutes to avoid scrambling the eggs later
- Mix Wet Ingredients:
- In a large mixing bowl combine the melted butter sugar eggs vanilla and coffee extract or dissolved instant coffee Blend until completely smooth with no streaks of egg
- Combine Dry Ingredients:
- In a separate bowl whisk together cocoa powder flour salt and baking powder Gradually scatter these over the wet mixture and fold gently until just combined The less you stir the fudgier your brownies will be
- Bake:
- Spread the thick batter evenly into your prepared pan Bake for about thirty to thirty five minutes Check with a toothpick in the center You want a few moist crumbs sticking for fudgy brownies Allow the pan to cool completely on a rack
- Prepare the Coffee Frosting:
- Dissolve your instant coffee granules in two tablespoons of heavy cream In a mixing bowl beat the softened butter thoroughly for a fluffy base Slowly add the powdered sugar mixing to combine Pour in the coffee cream then add more cream as needed to reach your favorite spreading consistency
- Frost and Serve:
- Gently smooth the coffee frosting over the completely cooled brownies Slice them into neat squares These brownies are ready to serve right away or can sit at room temperature to let all the flavors meld

Coffee is my secret weapon here I love how the extract boosts the chocolate but does not overpower The first ever batch I made became a hit at my book club and I have stuck with this frosting ever since
Storing Your Brownies
Keep brownies fresh by storing them in an airtight container at room temperature for up to three days For longer keeping refrigerate them and let come to room temperature before serving so the frosting softens If stacking brownies add a layer of parchment between layers to prevent sticking
Ingredient Swaps
No coffee extract on hand Use simply dissolved instant coffee or espresso powder Need to make it dairy free Swap butter for plant based margarine and heavy cream for canned coconut cream You can use gluten free all purpose flour blend to make these friendly for gluten sensitivities
Serving Suggestions
These brownies are wonderful alongside a cup of hot coffee or a cool glass of milk For an extra wow moment top each square with a chocolate covered coffee bean or a light dusting of cocoa powder I also love serving them slightly chilled on warm days for extra fudginess
Coffee Brownies and Culture
Coffee and chocolate share a long intertwined history both originating from tropical regions and celebrated in desserts worldwide Brownies themselves are an American classic but adding coffee brings a Continental twist reminiscent of Italian and French patisserie If you are curious about flavor pairings try adding a pinch of cinnamon or cardamom for a subtle spiced aroma
Frequently Asked Questions
- → Can I use brewed coffee instead of instant coffee or extract?
For this dessert, instant coffee or coffee extract is best to deliver intense flavor without diluting the batter. Brewed coffee is weaker and may alter the texture.
- → How do I achieve extra fudgy brownies?
Slightly underbake the brownies and let them cool completely before applying the frosting. This helps keep them dense and moist.
- → Can I freeze the brownies after frosting them?
Yes, you can freeze frosted brownies. Wrap them tightly and store in an airtight container for up to two months. Thaw before serving.
- → Is it possible to make the frosting less sweet?
Adjust the amount of powdered sugar to your liking, or add a pinch of salt to balance the sweetness in the coffee frosting.
- → What type of cocoa powder works best?
Unsweetened cocoa powder is preferred for a rich and chocolatey taste. You may use Dutch-processed for a smoother profile.
