Viral Paris Crookie: Buttery Croissants Stuffed with Cookie Dough Step-by-step instructions

Before you start

Before beginning, ensure the butter is browned and cooled to room temperature to prevent it from melting the chocolate chunks too quickly. Preheat the oven to 360°F (182°C) early so it reaches the target temperature before the assembly is complete.

Prepare a baking sheet with parchment paper to prevent the molten chocolate from sticking. Gather all ingredients and measure them precisely to ensure the dough consistency is correct.

Instructions

Dough preparation

1. 1Prepare the dough
   In a medium mixing bowl, whisk together the browned butter and brown sugar until smooth. Add the egg and stir until fully incorporated. Gradually fold in the all-purpose flour and dark chocolate chunks until a thick cookie dough forms. Ensure the dough is well-mixed but avoid overworking it to maintain the desired texture.
   Look for The dough should be cohesive and thick with evenly distributed chocolate chunks.
   Tip Use room temperature ingredients for the best emulsification.

The dough should be thick, glossy, and uniform in color. Check that the butter, sugar, and egg have emulsified into a smooth base before adding the dry ingredients. The final dough should hold its shape when pressed and have the chocolate chunks evenly distributed throughout to ensure every portion has an equal amount of chocolate.

Assembly of the pastries

2. 2Assemble the crookies
   Preheat the oven to 360°F (182°C). Using a serrated knife, slice each butter croissant horizontally through the middle, taking care not to separate the halves completely. Stuff approximately 80 grams of the prepared cookie dough inside each croissant. Close the croissant and press an additional 50 grams of cookie dough onto the top of each pastry.
   Look for The cookie dough should be centered and visible on top of the pastry.
   Tip Keep the croissant intact at the hinge for easier stuffing.

The croissants should be sliced carefully to maintain their shape. Check that each pastry is filled with exactly 80 grams of dough to prevent uneven baking times.

The top layer of dough should be pressed gently onto the croissant surface to ensure it adheres during the expansion process in the oven, creating that signature bakery aesthetic.

Baking and cooling

3. 3Bake and finish
   Place the assembled pastries on a parchment-lined baking sheet. Bake for 12 minutes until the croissant is golden brown and the cookie dough is set yet gooey in the center. Once removed from the oven, sprinkle immediately with flaky sea salt while the chocolate is still molten. Allow to rest for 5 minutes before serving to ensure the structure stabilizes.
   Look for The edges of the cookie dough should look crisp, while the center remains soft and melted.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Bake on the middle rack for even heat distribution.

The pastries should be golden brown, and the aroma of toasted butter and baking chocolate should fill the kitchen. Check that the center of the cookie dough is soft but not raw. The flaky sea salt should be applied immediately upon removal from the oven to allow it to adhere to the warm, melted chocolate pools.

Common mistakes

Avoid over-stuffing the croissants, as the dough will expand during baking and may spill out excessively. Ensure the croissants are not sliced all the way through, as the hinge is necessary to keep the pastry held together.

Do not skip the resting period, as the molten chocolate needs a moment to stabilize, or it will be too runny and difficult to handle when taking that first bite.

How to tell it’s done

The crookies are done when the croissant pastry is deep golden brown and crisp to the touch. The cookie dough on top should be set around the edges but remain soft and slightly molten in the center.

The safe temperature for the egg-containing dough is 160°F (71°C). If the top browns too quickly, cover the pastries loosely with aluminum foil for the final few minutes of baking.
