Place frozen puff pastry on the counter for 30 minutes to thaw.
02 -
While waiting for the pastry to thaw, pour chocolate chips into a bowl. Heat heavy cream in a saucepan over medium-low heat until steaming. Pour the hot cream over chocolate chips, let it sit for 1 minute and 30 seconds, and stir gently until smooth. Microwave in 15-second intervals if chunks remain. Let sit for 2 hours at room temperature until the texture becomes pudding-like.

In a small bowl, use a hand mixer to beat the cream cheese on high for 1 minute. Add sugar and beat again for 1 minute. Mix in vanilla extract.
04 -
Place thawed puff pastry sheets on a lightly floured surface. Push the seams together using your fingers. Cut each sheet into 3 long rectangles along the seams. Cut each rectangle in half to get a total of 6 rectangles per sheet.
05 -
Mix the egg with water in a small bowl. Use a pastry brush to spread the egg wash around the edge of each pastry rectangle.
06 -
Place the pastry rectangles on parchment-lined baking sheets, 6 per sheet. Use a sharp knife to lightly score another rectangle inside each pastry, leaving a ½ inch edge. Do not cut all the way through. This allows the pastry edges to puff up around the filling.
07 -
Spoon 1 tablespoon of the cream cheese filling onto the center of each pastry. Spread the filling inside the scored rectangle.
08 -
Place 1 prepared baking sheet in the fridge and the other in the freezer. Let the one in the freezer chill for 5 minutes before baking. This helps the butter in the pastry firm up.
09 -
Preheat the oven to 400°F. Bake one sheet of pastries at a time for 17-20 minutes, until golden brown. Let the pastries cool completely before baking the second sheet.

Once pastries are completely cool, spoon the chocolate ganache over the cream cheese filling, leaving some cream cheese visible around the edges.
