Preheat your oven to 400 degrees F.

While oven is pre-heating, remove one sheet of puff pastry from freezer. Let it slightly thaw before unfolding dough (15 minutes or so).

While dough is slightly thawing, prepare the cream cheese "filling". In a medium sized bowl, beat the cream cheese, granulated sugar, vanilla extract and whipping cream together, using an electric mixer. Mix for several minutes until mixture is smooth and spreadable. Set mixture aside.

Unroll the puff pastry carefully, and try to press dough together where the fold lines were. Cut dough into 8 rectangles (dough is cut in half, then in half again, then each of the 4 squares is cut in half once more).

Cover 2 baking sheets with parchment paper. Place 4 dough rectangles on each baking sheet, leaving ample space in between each piece. Take a sharp knife, and score a border all the way around the dough. Make sure to NOT cut all the way through to the bottom! (by cutting a border, the edges will rise up and hold the filling in better!-don't leave this step out!)

Evenly distribute the cream cheese filling onto the middle of each dough rectangle. Use a knife or spatula to spread it out over the top of the pastry dough, but stay inside the cut border!

Place a very small dollop of your favorite jam onto the cream cheese mixture. Use a toothpick and gently swirl the jam across the top of the pastry.

Mix the egg yolk and water in a small bowl. Using a pastry brush, brush the egg yolk mixture around the outer border of each pastry. While the dough is still "wet", sprinkle the border lightly with turbinado sugar.

Put the baking sheets into the oven and bake at 400 degrees F. for 13-14 minutes. The pastries should be golden around the edges. The dough should have also risen a bit. Take the pans from the oven and place them on a wire rack to cool completely.

Once the pastries are cool, mix the powdered sugar and lemon juice in a small bowl. (if too thick to drizzle, just add a bit more lemon juice!). Use a spoon, and drizzle the glaze over the cooled pastries (I went side to side). Let the glaze firm up, then pastries are ready to be served.

Enjoy!
