While booking a flight to Paris to taste the original might be a dream, making this flaky ooey-gooey dessert at home is surprisingly easy and arguably even more delicious when eaten fresh from your own oven. Whether you are a seasoned baker or just looking for a fun weekend project, this guide will teach you exactly how to make a crookie that rivals the best bakeries in the world.
The Story Behind Le Crookie
Before we preheat the oven, it is worth establishing the pedigree of this pastry. The Crookie was invented by Stéphane Louvard at the Boulangerie Louvard Paris. What started as a creative experiment to combine two beloved classics quickly exploded into a viral crookie TikTok trend. The concept is simple yet revolutionary: taking a day-old croissant (which holds up better to baking) and stuffing it with generous amounts of cookie dough before baking it again.
Ingredients: The Key to Perfection
The beauty of this recipe lies in its simplicity. You do not need a long list of obscure items. However, because there are so few ingredients, quality is paramount.

The Croissant Strategy
For the croissants, you have a few options. While you can make your own, a store-bought croissant recipe hack is the secret to getting this done quickly. In fact, using day-old croissants is preferred. Fresh croissants can be too soft and may collapse under the weight of the dough. Many home bakers find that Costco croissants recipe adaptations work exceptionally well due to their high butter content and substantial size, which allows them to crisp up beautifully without burning.
The Cookie Dough
For the cookie element, you can use a high-quality store-bought dough or make your own. If you are feeling adventurous, a brown butter cookie dough adds a nutty depth that pairs beautifully with the pastry. If you love the texture of The Best Monster Cookies Recipe, you know that the quality of the dough dictates the final result.
When selecting chocolate, consider the Potential health benefits of dark chocolate. Using bittersweet or semisweet chocolate chunks not only balances the sweetness of the dough but also provides a richer flavor profile compared to standard milk chocolate chips.
Step-by-Step: How to Make a Crookie
Creating this masterpiece is about assembly and timing. Here is how to achieve that perfect balance of textures.

1. Preparation
Begin by preheating your oven to 350°F (175°C). Proper temperature is crucial to ensure the cookie dough cooks without burning the croissant. Line a baking sheet with parchment paper to catch any melting chocolate or butter.
2. The Cut
Slice your 4-6 large butter croissants horizontally. You want to cut almost all the way through, creating a sandwich-style opening, but keep the back “hinge” intact if possible. This helps keep the filling secure.
3. Stuffing the Croissant
Take a generous portion of your 16 oz chocolate chip cookie dough (about 2-3 tablespoons per croissant) and flatten it slightly in your palms. Stuff this flattened dough inside the sliced croissant. Gently press the top of the croissant down to seal it.
If you are a fan of rich, chocolatey desserts like The Most Amazing Chocolate Cake, you will appreciate the density of the filling here. Do not be shy with the dough; the goal is a gooey center.
4. The Topping
This is the signature look of the viral crookie. Take additional small pieces of cookie dough and press them firmly onto the top of the croissant. As it bakes, this top layer will spread and crisp up, creating a “cookie crust” over the flaky pastry.
5. Baking and Doneness Safety Check
Place the assembled crookies on the baking sheet. Bake for 10 to 15 minutes. You are looking for the cookie dough on top to turn golden brown while the croissant becomes crisp.
Crucial Tip: Determining “doneness” can be tricky because the center is meant to be gooey. To ensure food safety, use a digital thermometer. The internal temperature of the dough needs to reach 160°F (71°C) to be safe to eat, even if the texture remains soft. This ensures you aren’t eating raw flour or eggs.
6. Cooling and Garnishing
Remove them from the oven. It is vital to let them cool for 5 minutes to set. If you try to eat them immediately, the dough will be molten lava. Once slightly cooled, dust with powdered sugar and sprinkle with flaky sea salt. The salt cuts through the richness and highlights the chocolate.
Tips for the Perfect Crookie
Preventing Sogginess
One common question is: How can I prevent my Crookie from becoming soggy or greasy on the bottom?
The trick is using day-old croissants. Fresh croissants have a higher moisture content. By letting them sit out for a day, they dry out slightly, allowing them to absorb the butter from the cookie dough without turning into mush. Additionally, ensure your oven is fully preheated before baking.
Air Fryer Method
Can I make Crookies in an Air Fryer instead of an oven?
Absolutely! An air fryer crookie is a great option for small batches. Set your air fryer to 325°F (160°C) and bake for 6-8 minutes. Keep an eye on them, as air fryers circulate heat more intensely and can burn the top cookie layer faster than a conventional oven.
Flavor Variations
While the classic chocolate chip crookie is the standard, you can experiment with high-trending variations:
- Red Velvet Crookie: Use red velvet cookie dough with white chocolate chips inside the croissant. The vibrant red color against the golden pastry makes for a stunning presentation.
- Matcha Crookie: Incorporate matcha powder into a sugar cookie base. The earthy green tea notes cut through the butteriness of the croissant perfectly.
- The Peanut Butter Lover: Mix peanut butter chips into your dough filling for a salty-sweet combo.
- Mini Crookies: Use mini croissants for bite-sized treats. These are perfect for parties and require a shorter crookie bake time (about 8-10 minutes).
Serving Suggestions
The Crookie is a rich, decadent dessert. If you are serving this at a gathering, it pairs wonderfully with coffee or a cold glass of milk. Because it is so sweet, you might want to balance your menu. For example, if you are hosting a brunch, you could offer Oatmeal Muffins: The Best Easy Recipe alongside the crookies for those who prefer a lighter, grain-based option before indulging in the main event.
Storage and Reheating
If you manage to have leftovers (which is rare!), proper crookie storage is key. Keep them in an airtight container at room temperature for up to 2 days. To refresh them, pop them in the oven or air fryer for 2-3 minutes to restore the crispiness.

FAQ
What exactly is a Crookie and where did it come from?
The Crookie is a hybrid pastry consisting of a croissant stuffed and topped with cookie dough. It originated at Boulangerie Louvard in Paris, created by baker Stéphane Louvard.
Is it better to use homemade or store-bought croissants and cookie dough?
For the best texture, store-bought, day-old croissants are superior as they hold their shape better. For the dough, either works, but high-quality store-bought dough makes this an incredibly fast and easy recipe.
How can I prevent my Crookie from becoming soggy or greasy on the bottom?
Avoid using fresh, soft croissants. Allow store-bought croissants to sit out for 24 hours before using. This “staling” process strengthens the structure.
Can I make Crookies in an Air Fryer instead of an oven?
Yes. Lower the temperature to 325°F and reduce the cooking time to avoid burning the top before the inside is cooked.
This viral sensation is more than just hype; it is a genuinely delicious combination of textures and flavors. Whether you stick to the classic recipe or try a variation, the Crookie is a must-try for any baking enthusiast.
