Frosted Coffee Brownies Treat

Featured in Sweet Treats & Baked Goods.

Think chewy chocolate squares packed with coffee punch, all under a cloud of thick, sweet frosting. You start with a buttery mixture, add plenty of cocoa, toss in some instant coffee or a shot of coffee extract, then bake for an insanely gooey base. After cooling, whip butter with sugar, stir in creamy coffee, and swipe it on top so each piece is lush and bold. People love them at parties, as a mid-day pick-me-up, or just when you want to wow your sweet tooth with a jolt of flavor.

If you’re all about chocolate and want a fun hit of coffee in your dessert, you’ve gotta try these brownies. These homemade bars get a soft, dreamy coffee icing on top that really takes them over the edge. After I baked a batch for a fundraiser and noticed they were gone in minutes, I always pull out this go-to whenever I want something special for friends or just a treat after work.

The first time I made these was for a book group meet-up, thinking only the serious coffee fans would try them, but after one bite, everyone kept coming back for more and wanted to know how I made them

Dreamy Ingredients

  • Salt: just a pinch sharpens up every flavor so don’t skip it
  • All-purpose flour: keeps everything together, make sure it’s fresh for the best chewy squares
  • Vanilla extract: gives a mellow balance to chocolate and coffee, pick the real stuff if you can
  • Baking powder: bumps up the brownies just enough so they’re not too dense, always check it’s still good
  • Unsalted butter: melts into the batter for a smooth bite, better butter gives better brownies
  • Eggs: holds everything, use big, fresh ones for those perfect fudgy sides
  • Unsweetened cocoa powder: adds all that deep chocolate flavor, Dutch process will give you the best color and taste
  • Granulated sugar: sweetens and gives that shiny, crackly brownie top everyone loves
  • Coffee extract or instant coffee: packs in that coffee hit in both brownie and icing, go for your favorite blend or instant
  • For the Frosting
  • Powdered sugar: makes the frosting sweet and thick, sift first if you want it super smooth
  • Heavy whipping cream: gives that creamy texture, milk works if you’re out
  • Instant coffee granules: dissolve right in and blend smoothly, pick a flavor you like
  • Unsalted butter: makes that frosting rich and fluffy, quality makes a big difference

Step-by-Step Directions

Slice and Serve
Frost fully cooled brownies all over, then cut them into tidy squares with a damp knife for sharp corners. Time to dig in
Frost the Brownies
Once mixed, slowly add spoonfuls of the coffee cream until your frosting is thick but easy to spread
Prepare the Frosting
Dissolve instant coffee into your cream and blend into soft butter by beating with a mixer. Gradually add in your powdered sugar and keep going until the frosting’s nice and fluffy
Cool Completely
Give the brownies time to cool right in the pan first or your icing will just melt right off
Bake
Even out your batter in the pan and bake about 30 to 35 minutes. A toothpick poked in at the 30-minute mark should come out with some moist crumbs
Bring It All Together
Switch in the dry to the wet mix, stirring gently but not too much. That’s how you get the fudgiest bite
Combine Dry Ingredients
Mix flour, cocoa, salt, and baking powder in a different bowl and break up any clumps for the perfect chewy texture
Mix Wet Ingredients
Combine the cooled melted butter, sugar, eggs, and vanilla—stir until it looks pale and all comes together
Melt the Butter
Zap your butter in the microwave until melted but not bubbling, then let it cool down a bit
Prepare the Pan
Fire up your oven to 350 and set out an 8-inch dish. Line it with parchment and spray it down so nothing sticks

My mom (she’s a pro chef!) always reached for coffee extract to make brownies extra tasty. It turned those regular squares into something special, and whenever we baked together on a Sunday, it was just warm, chocolatey comfort and the smell of coffee drifting from her mug over everything.

Storage Tips

Pop your brownies into a sealed box and leave them at room temp—they’ll stay fresh for four days. If you want to stretch that, stick them in the fridge and they’ll be good for a week. For even longer, wrap slices up tight and put them in the freezer for up to three months. Take out and let come to room temp before munching for the best bite.

Ingredient Swaps

No dairy? Use plant-based butter and go for a non-dairy cream in the icing. Out of coffee extract? Just use extra instant coffee or toss in some espresso powder. Coconut sugar or a mix of brown and white sugar gives you a fun flavor switch too.

Serving Ideas

Honestly, these are awesome on their own, but if you wanna snack fancy, add whipped cream or a scoop of vanilla ice cream. I like dusting them with cocoa powder or tossing on chopped chocolate for a snazzy look. Make brownie sundaes or slide pieces into lunchboxes for a cool midday sweet fix.

Cultural Touch

Coffee and chocolate are an American classic, but for us, this dish means those lazy Sundays around the table, everyone laughing and grabbing another piece. One bite, and it’s like going back to those simple, happy mornings.

Frequently Asked Questions

→ How do these brownies get so fudgy?

It comes down to melted butter plus just the right amount of eggs and sugar. This combo keeps the centers soft and dense.

Beat soft butter with powdered sugar, then slowly mix in cream whisked with your coffee. Just keep going until it's smooth and easy to spread.

→ What's the best way to keep leftovers fresh?

Pop them in a snug container. They'll stay good at room temp for a few days or last in the fridge for about a week.

→ Can I freeze these squares ahead of time?

Definitely! Wrap each piece up, freeze for up to three months, and bring one out when you want a sweet fix.

→ Which pan gives the chewiest brownies?

Grab an 8-inch baking pan if you want chunky, chewy pieces with crispy edges and soft centers.

Ingredients

→ Brownie Base

01 113 grams unsalted butter
02 200 grams granulated sugar
03 2 large eggs
04 1 teaspoon vanilla extract
05 2 teaspoons coffee extract or 1 tablespoon instant coffee
06 35 grams unsweetened cocoa powder
07 65 grams all-purpose flour
08 1/4 teaspoon salt
09 1/4 teaspoon baking powder

→ Coffee Frosting

10 1 1/2 teaspoons instant coffee granules
11 2-4 tablespoons heavy whipping cream
12 75 grams unsalted butter
13 240 grams powdered sugar

Instructions

Step 01

Once the brownies are covered in the coffee frosting, cut them into 16 even pieces and dig in.

Step 02

Mix instant coffee into 2 tablespoons of heavy whipping cream and let it sit. Whip the butter with a hand or stand mixer until it gets super fluffy. Gradually mix in powdered sugar until it looks smooth, then pour in your coffee-cream blend. Toss in more cream if you want the icing thinner or easier to spread.

Step 03

Let brownies chill in the pan, right on a cooling rack. Make sure they're not warm before you add the frosting.

Step 04

Dump the mixture in your ready pan and spread it out. Pop it in the oven for 30 to 35 minutes. Check with a toothpick—if it mostly comes out clean, you're good.

Step 05

Toss in cocoa powder, flour, salt, baking powder, and your coffee flavor straight into the wet bowl. Don't overmix—just blend until it barely comes together.

Step 06

Whisk together the melted butter, sugar, eggs, and vanilla in a big bowl until it all looks the same.

Step 07

Zap the butter in a microwave-safe dish till it’s all melted. No chunks left.

Step 08

Fire up your oven to 175°C. Cover a 20 cm square pan with some parchment and spray to stop stuff from sticking.

Notes

  1. If you want your icing to stay pretty, make sure those brownies aren't warm when you frost them.
