Puff pastry chocolate croissants are flaky, chocolaty, and delicious. These easy-to-make pastries utilize pre-made puff pastry and semi-sweet baking chocolate. The recipe requires only 3 main ingredients and minutes to prepare. Chocolate croissants are now possible any day of the week!
Preheat the oven to 400° F and line a baking tray with parchment paper. Cut each square of the semi-sweet chocolate baking bar in half. Then, roughly cut each half of the chocolate into pieces (these will be your portions for each croissant).
Whisk the room-temperature egg and a tablespoon of water to make the egg wash.
Roll out the puff pastry sheet to a 10x12-inch rectangle on a lightly floured surface. Cut the rolled-out sheet of puff pastry into eight 3x5-inch rectangles using a sharp knife or a bench scraper.
Place the portioned chocolate pieces a little from the edge of each puff pastry rectangle. Brush a little egg wash onto the opposite end of the puff pastry. Gently roll the puff pastry, starting at the side with the pieces of chocolate, securing each roll closed with the egg-washed end.
Transfer the unbaked chocolate croissants to the prepared lined baking sheet, evenly spacing them out. Brush the top of each puff pastry croissant with egg wash. Bake the croissants for 18-20 minutes, until golden brown and cooked through. Refrain from opening the oven until the last few minutes of baking.
Dust with powdered sugar, if desired, and serve immediately while still warm.
