Take the puff pastry out of the freezer and let it thaw for about 25 minutes. Preheat the oven to 425 F.
Flour your working surface area and very carefully unfold the puff pastry. With a floured rolling pin, roll it into a 10x11-inch rectangle. Transfer this rectangle to a parchment paper-lined baking sheet.
Using a pastry brush moisten the edges with a little water and fold them over to create a raised edge.
Using a fork, poke holes all over the surface of the pastry (except the edges), brush it with egg wash (including the edges), and sprinkle 2 tsp of sugar evenly over the whole crust. Bake it for about 15-20 minutes. If the center puffs up, don’t worry, just gently press it down with a wooden spoon or spatula.
Let it cool down for about 5 minutes and transfer to a cooling rack while you make the filling.
Make the filling by whisking the cream cheese and the sugar until smooth. Pour in the heavy cream and mix until incorporated. Gently fold in the lemon curd just until combined.
Spread the filling into the cold pasty base evenly up to the edges. Place the fresh raspberries in even lines over the filling and drizzle warm raspberry jam over the entire tart. To finish, dust it with powdered sugar.
