Step 1

Thaw puff pastry at room temperature for no more than 40 min. Sheets should still be cold when you begin working with them.

Step 2

Preheat oven to 400 degrees.

Step 3

Line a baking sheet with parchment paper.

Step 4

Beat together cream cheese and sugar until smooth. Add vanilla and egg yolks and and stir to combine.

Step 5

Roll out puff pastry on a floured surface, and cut each sheet into four equal squares.

Step 6

Make "L" shaped incisions in the corners of each square, ensuring that the incisions meet in the corners, but not in the center of the sides.

Step 7

Spoon 1/8 of the filling into the center of each of the squares.

Step 8

Lifting from the corners, fold the corners of each square into the center, allowing the connected sides to hold the square shape of the pastry.

Step 9

Top each pastry with five berries.

Step 10

Brush the egg whites onto the exposed puff pastry.

Step 11

Transfer to the baking sheet and bake for about 12-15 min (will vary by oven), or until golden brown. Do not overbake!

Step 12

Dust with powdered sugar and serve immediately.
