Frosted Mocha Brownies (Rich and Fudgy)

Frosted mocha brownies are the dessert that, once served, will be requested again and again. Fair warning.

Brownies are sort of the quintessential thumbs-up dessert in our home. When a chocolate craving hits, a gooey brownie is usually the cure.

It’s also something I can easily whip up when family is “coming down today”. (That’s Midwest for: company’s coming. From any direction.)

For years I relied on store-bought mixes. And they’re still pretty great in my opinion. But I don’t always have a box on hand.

Since I started making a well-stocked pantry a priority a few years ago, I have made sure I always have what I need for homemade brownies.

You never know when you will have a fudgy mocha brownie emergency. And trust me, once you try one, it becomes an emergency to not have one (once in a while.)

The recipe that I’m sharing today is for mocha brownies with coffee frosting. Yes, that’s a double mocha brownie, if you’re counting.

And I’m pretty confident it beats any prepackaged mix. You’ll just have to take the challenge and see for yourself!

Mocha brownies with brewed coffee

If you’ve made mocha desserts in the past, you’ll notice that some use espresso powder, and some use brewed coffee.

Personally, I like recipes like these chocolate coffee brownies that use brewed coffee instead. There’s always coffee in the cupboard, and I think the flavor is a little better.

Maybe it’s just me, but I can easily get carried away with the espresso powder and it can be a bitter surprise!

The coffee in this recipe mostly just enhances the chocolate flavor, bringing out the more rich, deeper notes. Kinda like a good mocha should!

If you decide to try espresso powder in place of the coffee, I won’t judge, though. We substitute the powder in our homemade frappes when we’re in a hurry. I get it.

How to make frosted mocha brownies

First, you’ll want to brew your coffee so it can cool. This recipe only uses 4 tablespoons total, but you’ll want to make it strong. Any nice dark coffee will do.

So if you’re using a single-cup coffee maker, use the smallest ounce setting (4 to 6 ounces will work).

While the coffee cools, you can melt the butter and dark chocolate chips together in a saucepan, whisking in the sugars once melted.

After removing from the stovetop, it’s time to whisk in the eggs, coffee, flour, and then the salt, one ingredient at a time.

You might notice there’s no leavening agent such as baking powder or baking soda. This makes for the perfect fudgy texture we’re going for. Trust me on this.

After all ingredients are combined well with a whisk, it’s time to transfer to a parchment-lined baking pan (8×8 or thereabout).

Next, it’s time to bake for approximately 25 minutes until it meets the clean-toothpick test.

Making the frosting: chocolate and coffee brownies

In the meantime, you can start another saucepan of dark chocolate chips and butter and melt on the stovetop. (Butter + chocolate chips = never wrong.)

Once melted, you’ll remove from the stovetop and add the remaining 2 tablespoons of coffee, along with some milk, powdered sugar and sea salt.

Brownies are ready to frost once they’re completely cool.

I like to use a large pizza cutter to cut brownies into even squares.
