This crookie dessert combines the flakiness of croissants with the gooey comfort of chocolate chip cookies for an indulgent treat that's been sweeping Paris bakeries and social media. When I first tried creating these at home, my family couldn't believe we didn't need to visit a fancy French patisserie to enjoy such a perfect hybrid dessert.
I discovered this viral sensation during lockdown when French pastries seemed a world away. After perfecting my recipe, these crookies have become our Sunday morning tradition, with my children eagerly measuring ingredients while waiting for that magical moment when cookie meets croissant.
Ingredients
- Salted Butter: The brown butter adds nutty caramel notes that elevate the entire dessert. Look for European style butter for richer flavor
- Granulated Sugar: Creates the perfect crisp exterior while helping with browning
- Light Brown Sugar: Adds moisture and a deeper molasses flavor that plain sugar lacks
- Egg: Binds the cookie dough and adds richness. Room temperature works best
- Vanilla Extract: Pure vanilla extract provides warm aromatic notes. Avoid imitation versions for best flavor
- All Purpose Flour: Creates structure for the cookie dough. Measure accurately by spooning into measuring cups
- Baking Soda: Provides just enough lift without making the cookie too cakey
- Dark Chocolate Chips: The bittersweet flavor balances the sweetness perfectly. Choose at least 60% cacao for best results
- Croissants: Fresh bakery croissants work best. Look for medium sized ones with visible layers
- Sea Salt: Flaky finishing salt provides delightful contrast to the sweetness
Step-by-Step Instructions
- Brown the Butter:
- Heat butter in a saucepan over low heat, watching carefully as it sizzles and bubbles. The noise will gradually subside as water evaporates. Continue cooking until milk solids turn a fragrant amber brown color, about 5-7 minutes total. Immediately remove from heat and transfer to a heatproof bowl to prevent burning. Let cool for 5 minutes until warm but not hot.
- Create Cookie Base:
- Add both sugars to the browned butter and whisk vigorously until fully incorporated and slightly glossy, about 1 minute. The warm butter will partially dissolve the sugar crystals. Add egg and vanilla extract, whisking until mixture is smooth and ribbony. This creates the rich foundation for our cookie dough.
- Incorporate Dry Ingredients:
- Sift flour and baking soda directly into the wet mixture to avoid lumps and ensure even distribution of leavening agent. Stir gently with a wooden spoon or spatula just until flour streaks disappear. Fold in one third cup of chocolate chips, being careful not to overmix which would develop gluten and toughen the cookies.
- Assemble Crookies:
- Slice each croissant horizontally through the middle as you would for a sandwich. Take approximately 2 tablespoons of cookie dough, flatten into a disk, and place inside each croissant half. Sprinkle additional chocolate chips inside for extra chocolate pockets. Close the croissants gently. Top each assembled croissant with another 2 tablespoons of flattened cookie dough, pressing lightly to adhere. Add a generous sprinkle of chocolate chips on top for visual appeal.
- Bake to Perfection:
- Place prepared crookies on a parchment lined baking sheet with at least 2 inches between each one as they will spread slightly. Bake in preheated oven for exactly 12 minutes until the cookie portion turns golden brown while the croissant becomes deeply caramelized. The interior should remain slightly soft for that perfect gooey texture. Allow to cool for 2-5 minutes on the baking sheet before transferring to wire racks. Finish with a light sprinkle of flaky sea salt while still warm.

Brown butter truly transforms this recipe from good to extraordinary. The first time I used this technique, my husband declared these better than any bakery version. There's something magical about the nutty aroma that fills your kitchen during this process that signals something truly special is happening.
Make Ahead Options
For freshly baked crookies anytime, you can prepare the cookie dough up to 3 days in advance and store it covered in the refrigerator. When ready to use, let the dough sit at room temperature for 15-20 minutes until softened enough to work with. You can even assemble the crookies completely and refrigerate for up to 24 hours before baking. This makes them perfect for brunch gatherings where you want to minimize morning preparation.
Serving Suggestions
While these crookies are divine on their own, try serving them warm with a scoop of vanilla ice cream for an outrageous dessert. For brunch, pair with fresh berries and a cappuccino for the full Parisian café experience. During holiday seasons, I've added a light dusting of powdered sugar or drizzled white chocolate for festive presentations that always impress guests without requiring additional effort.
The Origin Story
The crookie originated in Paris at a bakery called Moulins Blancs before going viral on social media platforms in early 2023. This fascinating hybrid follows in the tradition of other famous crossover pastries like the cronut (croissant donut) and brings together French pastry precision with the comforting familiarity of American cookies. What makes the crookie special is how it maintains the distinct qualities of both original treats while creating something entirely new.
