In the food processor, place the sifted flour, powdered sugar, and butter in pieces and process for a few seconds until the butter is integrated.
Beat the egg with the water and vanilla extract. Add the flour and process for a few seconds to form a ball.
On a floured surface, knead the dough only until the butter is well distributed for a few seconds and form a ball.
Divide the dough in half and place the dough on a sheet of wax paper, putting another sheet of wax paper on top. Roll out the dough until it is 1/8 inch thick. Do the same with the other half. Chill the dough for 30 minutes in the freezer.
Remove the dough from the freezer and cut the cookies with a heart-shaped cutter. For half of the cookies, cut out the center with a round cutter to make holes in the cookies.
Bake on lightly greased trays at 190 degrees Celsius for 12 minutes, remove and let cool.
Put a little jam on the cookie without a hole and sprinkle powdered sugar on the other cookie with the hole. Place one on top of the other to form a sandwich. Repeat with the remaining cookies.
