Unfold puff pastry sheets and lay on a cutting board. Using a knife or pizza cutter cut into three equal strips. Cut each strip in half to make 6 rectangles
Place each rectangle on the baking sheet.
With a small paring knife lightly score another rectangle about 1 in from the edge. Use a fork to poke a few holes in the center. This will allow the outer edge to rise during baking.
In a medium bowl using a hand mixer add the softened cream cheese, sugar, almond extract, and vanilla and mix until creamy.
Spread equal amounts of the filling into the center rectangle
In a small bowl combine the blueberries and lemon juice and toss until coated. Add the blueberries evenly on top of the cream cheese.
In a small bowl whisk the egg and water, brush the egg wash around the outer edges of the pastry.
Bake for 18-20 minutes until the edges are golden brown and puffy.
Remove from oven and cool on a cooling rack for 10 minutes dust with powdered sugar.

Notes
You can add a glaze instead of powdered sugar over the top if desired. Mix together 1/2 cup powdered sugar and 2 teaspoons milk until combined. Drizzle the icing over the top once the pastries have cooled a bit.
