Gently roll out puff pastry on a sheet of parchment paper or floured board until it is large enough to cover the bottom of a large square dish and extend an inch up the sides. Prick all over with a fork. Brush with beaten egg and sprinkle with 2 tsp sugar. Bake at 425 degrees for 12-16 minutes, or until golden. Remove from oven and let cool.

Beat cream cheese with 1/3 cup sugar until sugar is incorporated. Add cream. Add lemon curd. Spread over cooled pastry leaving a small border at the edges. Place berries evenly on top. Microwave jam for 15-20 seconds just to melt. Drizzle over berries. Sprinkle with powdered sugar just before serving if desired. Cut into squares to serve.
