Heat oven to 350 degrees. In a large bowl, cut butter into the flour. Add the rest of the cookie ingredients, bring together quickly. Cover the dough and refrigerate about an hour.
Roll dough thinly and cut into circles of desired diameter. Using a smaller, round cutter, cut the center out of half the circles (or use a knife to cut squares). Remove scraps, reroll and cut more cookies. Then place on parchment-lined cookie sheet
Bake 10-15 minutes or until turning lightly brown around the edges. The cookie should be white or a light golden brown, but not dark.
When the cookies have cooled, sprinkle confectioners’ sugar on cookies with holes and spread a light layer of jam on the whole cookies. Press them together lightly, confectioners’ sugar and jam sides up. When set, store tightly covered.
