1/2 cup Raspberry or Black Currant Jam(can use other flavored jams), well stirred
Directions
Preheat your oven to 350 °F. Place the almonds on a baking sheet and bake about 8-10 minutes, or until lightly browned and fragrant. Remove from oven and once the nuts have cooled, place in a food processor, along with 1/4 cup white sugar, and process until finely ground.
In a separate bowl, whisk or sift together the flour, cinnamon, salt, and lemon zest.
In the bowl, beat the butter and remaining 1/2 cup sugar until light and fluffy (about 2-3 minutes). Beat in the vanilla extract and egg yolks. Finally, beat in the ground almonds and then the flour mixture. Divide the dough in half, cover each half with plastic wrap, and refrigerate until firm (30-60 minutes, or up to two days).
Preheat oven to 350 °F. Line two baking sheets with parchment paper.
Remove one ball of dough from the refrigerator. On a lightly floured surface roll out the dough until it is about 1/4 inch thick. Using a 3 inch cookie cutter (round, square, heart, etc.) cut out the cookies. Place the cookies about 1 inch apart on the prepared baking sheet. Use a smaller cookie cutter to cut out the centers of half of the cookies on the baking sheet. Reroll any scraps and cut out the remaining cookies. Repeat with the second ball of dough. (Note: If you find the cookies are soft, place the baking sheets with the unbaked cookies in the refrigerator for about 10 minutes to chill the dough. This will prevent the cookies from spreading and losing their shape when baked.)Bake the cookies for about12 minutes or until lightly browned around the edges. Remove from oven and place on a wire rack to cool.
Assemble Cookies: Place the cut out cookies on a baking sheet and lightly dust the tops with powdered sugar. Spread a thin layer of jam on the bottom surface of the full cookie (top of cookie will face out). Place the cut-out cookie on top and gently sandwich them together. Using a small spoon or a piping bag, fill the cut-out with a little more jam.
The filled cookies will soften when stored. If you want the cookies to stay crisp, assemble the day of serving. The assembled cookies can be stored in the refrigerator, in an airtight container, for several days.
