Linzer Stars

Directions

1. 1.

   Pulse flour, almonds, cinnamon, and salt in a food processor until almonds are finely ground (no larger than poppy seeds).

2. 2.

   Using an electric mixer at medium speed, beat sugar and butter in a large bowl until fluffy, about 3 minutes. Add egg; beat until well blended, about 1 minute. Beat in rum and vanilla. Reduce speed to low; add dry ingredients. Beat dough just to blend; gently knead if necessary to form a ball.

3. 3.

   Divide dough in half. Place each half between sheets of parchment or waxed paper. Working with 1 piece at a time, flatten dough into a disk; roll dough, occasionally lifting paper on both sides for easier rolling, until 1/8" thick. Chill dough in paper until very firm, at least 2 hours. DO AHEAD: Dough can be made 2 days ahead. Cover; keep chilled.

4. 4.

   Arrange a rack in middle of oven and preheat to 375°F. Line 2 baking sheets with parchment paper or silicone baking mats.

5. 5.

   Working with 1 dough disk at a time, remove top sheet of paper and, using 2" star cookie cutter, cut out cookies. Transfer to baking sheets, placing 1/2" apart; chill. Repeat with remaining dough. Gather scraps; repeat rolling, chilling, and cutting until dough is used.

6. 6.

   Using 1/2" star cookie cutter, cut out a star from the center of half the cookies. Working in batches, bake cookies until light golden brown, dry, and just firm to the touch, 11-13 minutes. (Cookies will firm up as they cool.) Transfer to a wire rack; let cool. DO AHEAD: Cookies can be baked 2 days ahead. Store airtight at room temperature.

7. 7.

   Bring jam and 1 teaspoon water to a boil in a small saucepan; let cool slightly.

8. 8.

   Arrange whole cookies flat side up. Spoon 1 teaspoon cooled jam in the center of each, dabbing slightly to spread. Arrange cookies with cutouts flat side down on a wire rack; dust with powdered sugar. Set atop whole cookies, lining up star points and allowing jam to push up slightly through center. DO AHEAD: Linzer Stars can be assembled 8 hours ahead. Store airtight at room temperature.
