Mocha Brownies

For most people, brownies are a cozy, heavy dessert that are baked primarily during the cooler winter months. I buck the trend. I start to crave brownies most when the birds start to chirp, the sun stays up until 8pm, and it’s shorts and bathing suit weather. Totally irrational, and probably not smart, but the taste buds want what the taste buds want. Apparently, my taste buds want rich, dense, fudgy brownies during the spring and summer months. So, I appease them. A few weeks ago, I fell head over heels in love with the Chocolate Fudge Brownies with Chocolate Buttercream Frosting. They took me back to my high school days, to a simpler time, a time when a really good brownie could right all of those teenage wrongs. I decided that I needed to make more frosted brownies in the future. As you can see, I didn’t wait very long. I positively adore my Mocha Cupcakes with Espresso Frosting, and decided that was the perfect next step in my frosted brownie journey.

I took those amazing chocolate fudge brownies and adapted them for my mocha purposes, and then slathered my (slightly tweaked) espresso buttercream over top. Rich, fudgy brownies spiked with espresso and topped with a fluffy cloud of buttery-sugar-espresso-ness. (That’s definitely a word.) If you love coffee-flavored sweets, you’re going to fall in love with these brownies. Amazingly, I’m not even a coffee drinker, but I *LOVE* any mocha-inspired drinks or treats. I suppose that’s probably because mocha involves chocolate. Go figure, right?!

Mocha Brownies
Ingredients
For the Brownies:
- ¾ cup (93.75 g) all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon (0.5 teaspoon) salt
- ½ cup (113.5 g) unsalted butter
- 3 ounces (85.05 g) unsweetened chocolate
- ½ cup (100 g) granulated sugar
- ½ cup (110 g) light brown sugar
- 4½ teaspoons (4.5 teaspoons) instant espresso powder
- 2 eggs
- 1 egg yolk
- 1 teaspoon vanilla extract
For the Frosting:
- ¾ teaspoon (0.75 teaspoon) vanilla extract
- ¾ teaspoon (0.75 teaspoon) instant espresso powder
- ½ cup (113.5 g) unsalted butter, at room temperature
- 1¼ cups (150 g) powdered sugar
- 1½ teaspoons (1.5 teaspoons) heavy cream
Instructions
- Make the Brownies: Preheat oven to 350 degrees F. Butter an 8-inch-square baking dish and line with parchment paper, letting the excess hang over the edges. Butter the parchment paper; set aside.
- In a small bowl, whisk together the flour, baking powder, and salt; set aside.
- Bring about an inch of water to a simmer in a medium saucepan. Place a medium, heatproof bowl on top of the saucepan (do not let it touch the water) and add the butter and unsweetened chocolate. Stir occasionally, until the chocolate and butter are completely melted and smooth. Remove the bowl from the saucepan and whisk in the granulated and brown sugars, along with the instant espresso powder. Whisk in the egg, the yolk, and the vanilla extract. Add the flour mixture all at once, and fold it into the chocolate mixture with a rubber spatula until combined.
- Pour the batter into the prepared pan and bake for 25 to 30 minutes, or until a thin knife inserted in the center comes out clean. Allow to cool completely; meanwhile, make the frosting.
- Make the Frosting: Mix the instant espresso powder into the vanilla until dissolved; set aside. Using the whisk attachment of a stand mixer, whip the butter on medium-high speed for 5 minutes, stopping once to scrape the sides of the bowl. Reduce the mixer speed to low and add the powdered sugar a little at a time, waiting until it is mostly incorporated before adding more. Once all of the powdered sugar has been added, scrape the sides of the bowl and increase the speed to medium-high and whip until fluffy, about a minute or two. Add the espresso and vanilla mixture and continue to mix at medium-high until it is completely incorporated. Scrap the sides of the bowl, add the heavy cream, and again whip briefly at medium-high speed until thoroughly incorporated.
- Spread the frosting onto the cooled brownies, and cut into squares. Store brownies in an airtight container, or tightly wrapped, at room temperature for up to 5 days.

I like the way you think! I was at the store earlier and bought some unsweetened chocolate, thinking I’d make one of your older brownie recipes, but I never made it past today’s post. I have to admit to changing the recipe slightly-I didn’t have the instant espresso powder, but I have an espresso machine so I used two shots in the brownies and a small amount in the buttercream. The texture of the brownies was a little more cake-like most likely due to the extra liquid, but the taste was still great!
Ohmy! What a brownie! I would really like all of them right know…
Brownies are good. Coffee/Mocha/Espresso brownies sound even better. Thanks!
I love brownies year round, as you do :-)
Mocha Brownies need to be in my life! :) My sweetheart and I are not buttercream fans (regrettably), so how do you think these would taste with a mocha mascarpone frosting? Your blog makes my heart happy!
Hi Karen, I think a mocha mascarpone would be absolutely fabulous as well!
I have been totally craving brownies so I think I’m going to have to cave after seeing this post! I love the frosting!
Chocolate and coffee rivals chocolate and peanut butter in my book!
I love a good mocha brownie and yours look perfect, Michelle! Love your creamy espresso frosting addition, too!
I haven’t made brownies in soo long… But the next time I do, I think they have to be mocha!
My kine of brownie!! Love chocolate and coffee flavors mingled.
These could not be more perfect.
For real, brownies all year round! Just top it off with ice cream to make it more of a summer treat :)

I think brownies are good for any time of year! Hehe. These look delicious. :)
Fudgy, rich brownies + mocha frosting?! It doesn’t matter to me if it’s warm out, those sound like the perfect comfort food! :)
Love the mocha addition, and how rich and dense these babies look!
I could eat brownies year-round, they’re one of my very favorite treats! I don’t drink coffee either, but I’m always looking for coffee-flavored baked goods I can make. These are going on the list! :)
I love any mocha baked good, so these are definitely right up my alley. Mocha buttercream on a brownie- genius!
Like you, I’m not a coffee drinker, but I do LOVE the smell of coffee, and I”m willing to try anything that tastes like coffee at least once. These brownies are so pretty, and I bet they taste god, too.
I love coffee or espresso in brownies, heck anything chocolate. What a great recipe! I have to give this a try,I know my Hubby would love it!!
I love mocha anything. I love the generous amount of frosting on them!!! And I believe brownies should be eaten year roun too!
These look delicious! But are they cakey or fudgey?
Hi Aggie, Definitely fudgy!
Brownies are comfort. They give you a chocolate fix and are like little bite-sized pieces of dense chocolate cake. What’s not to love?
THese sound fantastic!
Mmm love that frosting!!
I would LOVE to have one (or two) of these right now!!
Love mocha desserts and cakes… Love brownies… So i absolutely want to try these…. They look soooo delicious!!! Compliments!
Love these brownies! And that coffee frosting looks incredible!
I do love coffee flavored sweets and these mocha brownies sound amazing. And since they have coffee in them it’s perfectly acceptable to have them for breakfast….and during the rest of the day of course! Have a nice weekend.
I always put a few tablespoons of coffee in brownies b/c I really find it just enhances the flavor so much. Yours sound wonderful!
