Here are my brown butter espresso brownies, with nutty browned butter, deep chocolate flavor, a kick of espresso, and that perfect fudgy texture that makes brownies irresistible.

These brownies are what I make when I need something impressive but don’t want to spend all day in the kitchen. The brown butter adds this amazing depth, and the espresso makes the chocolate taste even more chocolatey without making them taste like coffee. They disappear fast at every gathering I bring them to.

Why You’ll Love These Brown Butter Espresso Brownies

Rich, complex flavor – The brown butter adds a nutty depth while the espresso powder brings out the chocolate flavor without making these taste like coffee.
Fudgy texture – These brownies are perfectly gooey and dense, with that crackly top that everyone loves.
Simple ingredients – You probably have most of these pantry staples on hand already, making this an easy treat to whip up whenever a chocolate craving hits.
Perfect for any occasion – Whether you need a dessert for a party, a bake sale contribution, or just something sweet for yourself, these brownies always deliver.

What Kind of Chocolate Chips Should I Use?

For these brownies, you can use whatever chocolate chips you have on hand – semisweet, milk chocolate, or dark chocolate will all work great. If you’re a fan of rich, intense chocolate flavor, go for dark chocolate chips with 60-70% cacao, but if you prefer something a bit sweeter, semisweet or milk chocolate chips are perfect. You could even mix different types together for a more complex flavor. If you don’t have chocolate chips, feel free to chop up a chocolate bar into chunks – they’ll melt into those gooey pockets of chocolate that make brownies so irresistible.

Options for Substitutions

These brownies are pretty forgiving when it comes to swaps, so here are some options if you need them:

Brown sugar: If you’re out of brown sugar, you can use all white sugar instead. Your brownies will be slightly less chewy and won’t have that caramel-like flavor, but they’ll still taste great.
Espresso powder: No espresso powder? Try instant coffee granules instead – use the same amount. You can also skip it entirely if coffee isn’t your thing, though it really does make the chocolate flavor pop.
Vegetable oil: Canola oil, melted coconut oil, or even more melted butter will work here. Each will give you slightly different results, but all will make fudgy brownies.
Chocolate chips: Feel free to use chopped chocolate bars, chocolate chunks, or even a mix of dark and milk chocolate. You can also toss in some nuts like walnuts or pecans if you want extra texture.
Butter: The brown butter is really what makes these special, so I’d recommend sticking with butter here rather than substituting. It adds a nutty, rich flavor that’s hard to replicate.
Cornstarch: If you don’t have cornstarch, just use an extra tablespoon of flour instead. The texture will be slightly less tender but still delicious.

Watch Out for These Mistakes While Baking

The biggest mistake when browning butter is walking away from the stove – it goes from perfectly nutty to burnt in seconds, so stay close and watch for those golden brown specks at the bottom of the pan.

Overbaking is another common issue that leads to dry, cakey brownies instead of fudgy ones, so pull them out when a toothpick inserted in the center comes out with a few moist crumbs, not completely clean.

Don’t skip whisking the eggs and sugar for the full 4 minutes, as this step creates that signature crackly top and helps build the right texture throughout.

For extra insurance against overbaking, remember that brownies continue cooking in the hot pan after you remove them from the oven, so let them cool completely in the pan before cutting for the best fudgy texture.

What to Serve With Brown Butter Espresso Brownies?

These brownies are rich and fudgy with a deep coffee flavor, so they’re perfect with a cold glass of milk or a scoop of vanilla ice cream on top. If you want to go all out, try serving them warm with some whipped cream and a drizzle of caramel sauce – the sweetness balances out the espresso really nicely. They also pair well with a hot cup of coffee or espresso for an extra caffeine kick, which makes them great for an afternoon pick-me-up. For a fun dessert spread, you can cut them into small squares and serve alongside fresh berries or some salted caramel popcorn.

Storage Instructions

Store: These brownies stay fudgy and delicious when kept in an airtight container at room temperature for up to 4 days. If you want them to last a bit longer, store them in the fridge for up to a week, though they might firm up a little in the cold.

Freeze: Brownies are one of my favorite things to freeze because they thaw so well! Wrap individual pieces in plastic wrap, then place them in a freezer bag for up to 3 months. This way you can grab just one or two whenever a chocolate craving hits.

Enjoy: Let frozen brownies thaw at room temperature for about 30 minutes, or if you’re impatient like me, pop them in the microwave for 10-15 seconds. They’ll taste like you just baked them, with that perfect fudgy center and crispy edges.

Ingredients

For the wet components:

3/4 cup butter (I like Kerrygold unsalted butter for this)
1/4 cup vegetable oil
3 large eggs (room temperature, about 70°F)
3/4 cup granulated sugar
3/4 cup light brown sugar, packed
2 1/2 tsp vanilla extract

For the dry mix:

3/4 cup all-purpose flour (I always use King Arthur all-purpose flour)
1/2 cup cocoa powder (sifted to remove lumps)
1 tbsp cornstarch
3 tbsp espresso powder
1/2 tsp salt
1/4 teaspoon baking powder

For the inclusions and garnish:

6 oz chocolate chips (I use Ghirardelli 60% cacao bittersweet chips)
flaky sea salt

Step 1: Prepare Pan and Brown the Butter

3/4 cup butter
parchment paper

Preheat your oven to 325°F and line a 9×13 inch baking dish with parchment paper, allowing it to overhang slightly on two sides for easy removal later.

While the oven preheats, melt the butter in a small saucepan over medium heat.

Once melted, continue cooking for 8-10 minutes, swirling occasionally, until the milk solids turn golden brown and develop a nutty aroma—this is the critical flavor-building step that distinguishes these brownies.

Pour the browned butter (including all those precious brown bits) into a bowl and set aside to cool slightly.

Step 2: Prepare Dry Ingredients

3/4 cup all-purpose flour
1/2 cup cocoa powder
1 tbsp cornstarch
3 tbsp espresso powder
1/4 teaspoon baking powder
1/2 tsp salt

While the butter cools, whisk together the flour, cocoa powder (sifted to remove lumps), cornstarch, espresso powder, baking powder, and salt in a medium bowl.

Set this dry mixture aside.

I like to sift the cocoa powder first because it ensures there are no lumps that will create bitter pockets in the final brownies.

Step 3: Melt Chocolate and Mix with Browned Butter

Pour the slightly cooled browned butter into a larger mixing bowl and add the chocolate chips.

Stir constantly for about 1-2 minutes until the residual heat melts the chocolate completely and creates a smooth, glossy mixture.

The warm butter will melt the chips without requiring additional heat.

Step 4: Create the Wet Ingredients Base

3 large eggs
3/4 cup granulated sugar
3/4 cup light brown sugar, packed
1/4 cup vegetable oil
2 1/2 tsp vanilla extract
chocolate mixture from Step 3

In a separate bowl, whisk together the room-temperature eggs and both sugars (granulated and brown) vigorously for about 4 minutes.

This aerating step is essential—it creates a light, fluffy structure that will give the brownies a tender crumb and fudgy texture.

The mixture should become slightly paler and have increased volume.

Pour in the vegetable oil and vanilla extract, then gently fold in the chocolate mixture from Step 3 until fully combined.

Step 5: Combine Wet and Dry Ingredients

Gently fold the dry ingredient mixture from Step 2 into the wet ingredients until just combined—do not overmix, as this can develop gluten and create a dense, cake-like texture.

Fold carefully with a spatula, working from the bottom of the bowl upward, until no white streaks of flour remain.

Step 6: Bake the Brownies

Pour the batter into the prepared baking dish and spread evenly.

Bake for 45-50 minutes at 325°F until a toothpick inserted into the center comes out with just a few moist crumbs clinging to it—do not overbake, as these brownies should be fudgy and moist rather than cakey.

The edges may pull slightly away from the pan when fully baked.

Step 7: Cool and Finish with Sea Salt

Allow the brownies to cool in the pan for at least 15-20 minutes before removing.

Once cool enough to handle, use the parchment overhang to lift the entire brownie slab onto a cutting board.

Sprinkle with flaky sea salt while still slightly warm—the salt will enhance the espresso and chocolate flavors and provide a delightful contrast to the rich sweetness.

Cut into squares and serve.
