To make gingerbread linzer cookies, use cookie cutters to cut out cookies. Use a smaller cookie cutter or a sharp knife to cut out the centers of half of the cookies. Alternatively, use linzer cookie cutters
. Once the cookies are baked and completely cool, spread fruit preserves, dulce de leche, chocolate ganache, or Nutella on the flat side of each solid cookie. Dust the top of the cut-out cookies with powdered sugar or decorate with royal icing. Top each solid cookie with a cut-out cookie.
