Cut fruitcake lengthwise in half. Shape each portion into 10 1/2-inch log on cooking parchment paper. Divide cookie dough in half. On lightly floured surface, roll each portion of dough into 11x9-inch rectangle. Place 1 fruitcake log on long edge of 1 dough rectangle; roll up jelly-roll fashion, starting from long side. Coat generously with nuts. Repeat with second portion of fruitcake and dough. Wrap tightly in plastic wrap; refrigerate 2 hours or until firm.
