Fudgy Brownie Cookies

All the joy of brownies in one chewy cookie

If you love the shiny top and deep chocolate flavor of a pan of brownies, these Brownie Cookies bring all of that to your cookie jar. You get crinkly tops, soft centers, and pockets of melted chocolate in every bite. They are easy enough for a weeknight sweet but feel special on a holiday tray or birthday plate. The batter comes together in one bowl, no chill time, and you can bake just a few at a time for fresh, warm cookies whenever the craving hits.

Time Breakdown

Time Breakdown: Prep 20 minutes  |  Bake 9–11 minutes  |  Cooling 10–15 minutes  |  Total about 40 minutes  |  Yield: about 15 cookies

Ingredients

• 3/4 cup (95 g) all-purpose flour
• 3/4 teaspoon baking powder
• 1/2 teaspoon fine sea salt or kosher salt
• 1 teaspoon instant espresso powder, optional (for deeper chocolate flavor)
• 1/3 cup (30 g) unsweetened cocoa powder
• 1 1/2 cups (270 g) semisweet or bittersweet chocolate chips, divided
• 5 tablespoons (70 g) unsalted butter, cut into pieces
• 2 large eggs, room temperature
• 1 large egg yolk, room temperature
• 1 tablespoon neutral oil (canola or vegetable)
• 1 cup (200 g) granulated sugar
• 1 1/2 teaspoons pure vanilla extract
• Extra chocolate chips for topping, optional
• Flaky sea salt for sprinkling, optional but lovely

Kitchen Tools

• 2 mixing bowls (one heat-safe)
• Small saucepan or microwave-safe bowl (for melting chocolate and butter)
• Hand mixer or stand mixer with paddle attachment (or a whisk and some patience)
• Rubber spatula
• 2 rimmed baking sheets
• Parchment paper
• 1 1/2 tablespoon cookie scoop or two spoons
• Wire cooling racks

Step-by-Step Instructions

1. Prep the pans. Preheat the oven to 350°F (175°C). Set oven racks in the upper and lower thirds. Line two baking sheets with parchment paper so the cookies release cleanly and do not stick.
2. Whisk the dry ingredients. In a medium bowl, whisk together the flour, baking powder, salt, espresso powder (if using), and cocoa powder until no streaks remain. Set aside.
3. Melt the chocolate and butter. In a small saucepan over low to medium-low heat, stir together the butter and 1 cup of the chocolate chips. Stir often until just melted and smooth. Remove from the heat and let it cool for 3–4 minutes so it is warm, not hot.
4. Beat eggs and sugar. In a large bowl (or the bowl of a stand mixer), add the eggs, egg yolk, oil, sugar, and vanilla. Beat on high speed for about 3 minutes, until the mixture looks thick, pale, and slightly fluffy. This step gives you that classic brownie-style texture.
5. Add the melted chocolate. With the mixer on low, slowly pour in the melted chocolate mixture. Mix just until combined, scraping down the sides and bottom of the bowl so everything blends evenly.
6. Add the dry ingredients. Sprinkle the flour mixture over the wet ingredients. Mix on low speed just until no dry streaks of flour remain. The batter will be glossy and fairly soft, thicker than brownie batter but thinner than typical cookie dough.
7. Fold in chocolate chips. Use a rubber spatula to fold in the remaining 1/2 cup chocolate chips. Make sure they are scattered through the batter.
8. Rest the batter. Let the bowl sit at room temperature for 10 minutes. The batter will thicken slightly as it stands, which helps the cookies spread to the right shape in the oven while staying chewy inside.
9. Scoop the cookies. Using a 1 1/2 tablespoon cookie scoop or two spoons, portion mounds of batter onto the prepared baking sheets, spacing them about 2 inches apart. The batter will still look soft and a bit loose. If you like, press a few extra chocolate chips on top of each mound and gently flatten the tops just a touch with your fingers.
10. Bake. Bake the cookies for 9–11 minutes, rotating the baking sheets from top to bottom halfway through. The cookies should have shiny, crackly tops and edges that are set, but the centers will still look soft and slightly puffed. They will continue to firm up as they cool.
11. Add flaky salt and cool. If using, sprinkle the tops with a pinch of flaky sea salt as soon as the trays come out of the oven. Leave the cookies on the baking sheets to cool for at least 10–15 minutes. They will be too delicate to lift right away; once cooled, they will be fudgy but sturdy enough to move to a rack.
12. Serve and store. Enjoy slightly warm with a glass of milk or a cup of coffee. Store cooled cookies in an airtight container at room temperature for up to 3 days.

Pro Tips for the Best Brownie Cookies

• Room temperature eggs: Cold eggs can make the batter stiff and dull. Let them sit out for 20–30 minutes, or place them (still in the shell) in a bowl of lukewarm water for 10 minutes.
• Watch the chocolate as it melts: Heat it low and take it off the burner as soon as it is smooth. Overheating can make it grainy and change the texture of your cookies.
• Do not skip the rest time: That 10-minute rest gives you just the right thickness. Less rest gives you thinner, more spread-out cookies; longer rest gives you thicker, more domed cookies.
• Espresso powder is flexible: Add it for a grown-up, café-style depth of flavor, or leave it out for a sweeter, kid-friendly batch.
• Check doneness by the edges: The edges should look set and slightly dry, while the centers still look soft. If they look fully baked in the oven, they will end up dry once cooled.

A quick note from my kitchen

These brownie cookies appeared on a very long Tuesday. One kid had soccer, one had piano, and my youngest was begging for brownies “with the shiny top.” I did not have time to wait for a whole pan to bake and cool, so I grabbed my cookie scoop and turned our favorite batter into cookies instead. We pulled the first tray from the oven right before homework time, and the kids lined up at the counter with glasses of cold milk. Now this is our “just because” dessert for crowded days when we still want something home-baked and comforting.
