The flavors in this bar were inspired by linzertorte, a classic European dessert that originated in Linz, Austria.
Make these fabulous bars ahead of time. Line your pan with foil, leaving the edge of the foil above the rim of the pan on two opposite sides; grease foil in bottom of pan lightly. Bake bars as directed. When cool, use foil "handles" to remove the whole rectangle from the pan. Wrap airtight and freeze. Before serving, unwrap and let stand about 1 hour until room temperature.
Bars can also be baked in a 17x11x3/4-inch pan.
