I've been making these Date Pinwheels for years. They're a family favorite and a favorite on the cookie trays we give away every Christmas.
Place dough on a lightly floured surface; rollin to a 16" x 8" rectangle. Spread filling over dough, leaving a 1/2" margin on all sides. Starting at long side, carefully roll dough, jellyroll fashion; pinch seam and ends of roll to seal. Wrap dough in wax paper, and chill at least 1 hour.
