Add a festive flair to the Christmas dessert table with these tender Linzer cookies; this recipe is a holiday tradition in Austria. The decorative cutout on the top cookie allows the luscious raspberry jam filling to peek through, hinting at the delicious flavor to come.
In small bowl, combine flour, almonds, and cinnamon; set aside. In large bowl, beat butter and sugar with electric mixer until light and fluffy. Add egg and vanilla; mix well. Add flour mixture; mix only until incorporated. Divide dough onto 2 pieces; press into small disks, about 1 inch thick. Wrap separately in plastic wrap and refrigerate 2 hours or until firm enough to roll.
Preheat oven to 350°F. On floured surface, roll out one disc of dough 1/8 in. thick (keep remaining dough chilled). Cut half of the dough using the round cutter with your chosen insert (this is top cookie); cut an equal number of rounds using the cutter without the insert (this is the bottom cookie). Transfer to parchment paper lined baking sheets. Dough scraps can be formed into a disk, chilled for at least 30 minutes and rerolled.
Bake 10-12 minutes or until light golden brown. Cool on cookie sheet 2 minutes; remove from sheet and cool completely. Invert bottom cookies; spread with about a teaspoon of jam. Dust the top cookies with confectioners' sugar; gently sandwich cookies together.
