Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
02 -
On a lightly floured surface, roll out the puff pastry sheet to smooth any creases.
03 -
In a small bowl, combine chocolate chips, brown sugar, melted butter, and vanilla extract. Stir until the mixture is evenly combined.
04 -
Spread the chocolate mixture evenly over half of the pastry sheet. Fold the other half of the pastry over the filling to enclose it.
05 -
Using a sharp knife or pizza cutter, slice the folded pastry into 1-inch strips. Carefully twist each strip a few times to create a spiral shape. Place each twist on the prepared baking sheet, spacing them about 1 inch apart.
06 -
Brush each twist with the beaten egg to achieve a golden, glossy finish. Bake for 15-18 minutes, or until the twists are golden brown and puffed.
07 -
Allow the twists to cool slightly. Dust with powdered sugar for a finishing touch, if desired. Serve warm or at room temperature.
