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.
