Description
When we talk about fudgy brownie cookies, we are describing a specific type of cookie that leans heavily into the chemistry of a brownie. Unlike a traditional chocolate chip cookie, which relies on a higher ratio of flour to fat to maintain a sturdy structure, these cookies use a high concentration of melted chocolate and a specific whisking technique to achieve a dense, fudgy crumb.
Ingredients
½ cup (115 g) unsalted butter
1 cup (170 g) semi-sweet chocolate chips (or chopped chocolate)
¾ cup (150 g) granulated sugar
¼ cup (50 g) brown sugar
1 large egg
1 tsp vanilla extract
¾ cup (95 g) all-purpose flour
¼ cup (25 g) unsweetened cocoa powder
½ tsp baking powder
¼ tsp salt
Optional: extra chocolate chunks, flaky salt on top
Instructions
Melt the chocolate
In a microwave or over a double boiler, melt the butter + 1 cup chocolate chips together.
Stir until smooth and glossy. Let cool slightly (important so the egg doesn’t scramble).
Mix the sugars
Whisk the melted chocolate with granulated sugar + brown sugar.
Add the egg and vanilla, whisk hard for ~30 seconds until thick and shiny (this helps give that crackly top).
Dry ingredients
In a separate bowl, whisk flour, cocoa powder, baking powder, and salt.
Combine
Fold dry ingredients into the chocolate mixture just until combined.
Dough will be soft and thick (almost like brownie batter that barely holds shape).
Chill (important!)
Chill dough for 15–20 minutes so cookies don’t spread too much.
Bake
Preheat oven to 350°F (175°C).
Scoop 2-tbsp portions onto a lined baking sheet, spaced apart.
Bake 9–11 minutes — edges set, centers still soft.
Cool
Let cookies cool on the pan for 5 minutes (they firm up but stay fudgy).
Optional: sprinkle flaky salt on top ✨
Notes
These fudgy brownie cookies are best enjoyed slightly warm, when the centers are soft and gooey. Don’t overbake—underbaking is the secret to that perfect brownie texture.
