Preheat your oven to 325° F.
Remove one piece of dough from the refrigerator and cut out as many 2” circles as you can. Place them on a parchment lined baking sheet, chill for 15 minutes and bake for 17-18 minutes, or until the edges just begin to turn a light golden brown. Place the baking sheet on a rack to cool for about 5 minutes. Place the cookies directly on a rack to cool completely.
Remove the other piece of dough from the refrigerator and using the same cutter, cut out the same amount as with the previous piece of dough. Place them on a parchment lined baking sheet. Using a smaller cutter. Cut out the center of the cookies. Bake for about 16-17 minutes.
You can reroll the scraps once and cut out additional cookies.
Once the cookies are cool, dust the tops of the cookies, with the cut out, with powdered sugar.
Fill a pastry bag with preserves and squeeze out about 1-2 teaspoons of preserves on the bottom of the solid cookie.
Top with a cut out cookie.
