This rich and indulgent chocolate brookie recipe delivers the perfect hybrid between a brownie and a cookie. The crackly tops and fudgy centers create an irresistible texture that chocolate lovers will crave time after time.
I first developed these brookies during a rainy weekend when my children were begging for both brownies and cookies. This compromise creation quickly became our most requested treat and now makes an appearance at nearly every family gathering.
Ingredients
- Plain flour: provides the structure without overwhelming the chocolate flavor
- Cocoa powder: intensifies the chocolate taste and contributes to the fudgy texture
- Dark chocolate: choose high quality with at least 70% cocoa solids for the richest flavor
- Butter: use European style for extra richness if available
- Eggs: must be at room temperature to properly incorporate air when whipped
- Caster sugar: dissolves easily creating a smoother texture in the final brookie
- Demerara sugar: adds wonderful caramel notes and creates that signature crackly top
- Vanilla extract: enhances the chocolate flavor use pure rather than imitation
- Chocolate chips: create pockets of melty goodness throughout each brookie
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to 160ºC with a fan or 170ºC conventional. This moderate temperature allows the brookies to develop their signature crackly top while maintaining a fudgy interior. Line your baking tray with parchment paper ensuring it extends slightly beyond the edges for easy removal.
- Melt Chocolate and Butter:
- Combine chopped dark chocolate and butter in a heatproof bowl. Create a double boiler by placing this bowl over a pan with about an inch of simmering water. Ensure the bowl doesn't touch the water to prevent scorching. Stir gently every 30 seconds until completely smooth and glossy. The mixture should look silky with no visible streaks. Remove from heat and stir in vanilla.
- Whip Eggs and Sugars:
- In a medium bowl beat the caster and demerara sugars with the eggs using an electric mixer. This step is crucial for the perfect texture. Continue beating on high speed for a full 5 minutes until the mixture has nearly tripled in volume and becomes pale and mousselike. When you lift the beaters the batter should fall in thick ribbons that hold their shape momentarily.
- Combine Dry Ingredients:
- Sift the flour cocoa powder baking powder and salt together into a separate bowl. This removes lumps and incorporates air for a lighter texture. Add chocolate chips and toss to coat them in the dry mixture which prevents them from sinking to the bottom during baking.
- Integrate Chocolate Mixture:
- Pour the cooled chocolate butter mixture around the edges of the whipped egg mixture. Use a rubber spatula to fold gently with a scooping motion from bottom to top. Maintain as much air as possible in the batter for that perfect chewy texture. The mixture should be marbled at first then fully incorporated.
- Fold in Dry Ingredients:
- Add the flour mixture in two additions folding delicately after each addition. Stop mixing as soon as no dry streaks remain. Overmixing at this stage will develop gluten and result in tough brookies instead of tender ones.
- Bake the Brookies:
- Use a tablespoon or cookie scoop to portion the batter onto your prepared tray allowing at least 2 inches between each brookie for spreading. Bake for precisely 12 minutes for fudgier centers or 14 minutes for slightly firmer brookies. The tops should be crackly and dry while the centers remain slightly soft.
- Cool and Finish:
- Remove from oven and if desired sprinkle immediately with flaky sea salt which enhances the chocolate flavor. Allow brookies to cool on the tray for 10 minutes where they'll continue cooking slightly from residual heat. Transfer to a wire rack to cool completely though they're particularly delicious while still slightly warm.

The combination of two different sugars is my secret weapon in this recipe. The demerara sugar not only adds complexity with its caramel notes but creates that irresistible crackly top that makes these brookies so visually stunning. My daughter now insists on helping make these every time because she loves watching the transformation as they bake.
Perfect Storage Solutions
These brookies maintain their fudgy texture best when stored in an airtight container at room temperature for up to 3 days. Place parchment paper between layers to prevent sticking. For longer storage freeze fully cooled brookies in a single layer then transfer to a freezer bag. To enjoy warm again microwave a frozen brookie for 15 seconds or thaw at room temperature for 30 minutes.
Clever Substitutions
No demerara sugar? Brown sugar works wonderfully as a substitute though the texture will be slightly different. White chocolate can replace dark chocolate for a sweeter less intense flavor profile. For gluten free brookies substitute the all purpose flour with a 1 to 1 gluten free baking blend. Add 1/4 teaspoon xanthan gum if your blend doesn't include it already.
Serving Suggestions
Transform these brookies into an elegant dessert by serving them warm with a scoop of vanilla bean ice cream and a drizzle of salted caramel sauce. For a fun family dessert build brookie ice cream sandwiches using slightly undercooked brookies. They also make perfect gifts packaged in cellophane bags tied with ribbon or stacked in decorative tins for holiday giving.
The Science Behind Perfect Brookies
The success of these brookies lies in the balance between structure and tenderness. The minimal flour creates that fudgy texture while the extended whipping of eggs creates air pockets that give the brookies their height. The melted chocolate rather than cocoa alone provides fat that slows gluten development ensuring a tender final product. Baking at a slightly lower temperature allows the interior to set without overcooking the edges.
Recipe FAQs
- → What makes brookies different from regular brownies or cookies?
Brookies are a hybrid dessert that combines the fudgy, rich texture of brownies with the shape and crisp edges of cookies. They feature the dense chocolate flavor profile of brownies but bake up in individual portions like cookies, offering a crackly top with a chewy interior.
- → Can I substitute the Demerara sugar?
Yes, you can substitute Demerara sugar with turbinado sugar or raw sugar, which offer similar large crystals and subtle molasses flavor. In a pinch, light brown sugar can work, though it will alter the texture slightly as it doesn't provide the same crunch.
- → Why do my brookies need to cool on the tray first?
Cooling brookies on the tray for about 10 minutes is crucial as they continue to set during this time. The residual heat helps solidify their structure while maintaining the fudgy interior. Moving them too soon can cause them to break apart as they're quite soft when first removed from the oven.
- → How do I know when my brookies are perfectly baked?
Perfectly baked brookies will have a set, crackly top but should still seem slightly underdone in the center (they'll continue cooking from residual heat). Look for edges that are just set while the center remains soft. Overbaking will result in drier brookies that lose their signature fudgy texture.
- → Can I freeze these brookies?
Yes, these brookies freeze excellently for up to 3 months. Allow them to cool completely, then store in an airtight container with parchment paper between layers. Thaw at room temperature for about an hour before serving, or warm briefly in a microwave for 15-20 seconds for that fresh-baked texture.
- → What's the importance of whisking the eggs and sugar thoroughly?
Whisking eggs and sugars until thick and fluffy (about 5 minutes) creates the characteristic crackly top and helps incorporate air into the batter. This step creates the foundation for the brookies' texture, providing structure while maintaining a fudgy interior. Underdoing this step will result in denser, flatter brookies.
