PREHEAT oven to 325° F. Line 15 x 10-inch jelly-roll pan with foil; grease lightly.
CRUMBLE two whole bars of dough into prepared pan. Using fingertips, pat dough gently to fill the pan.
BAKE for 15 to 20 minutes or until light golden brown. Cool completely in pan on wire rack. Remove from pan using foil handles, remove to cutting board. Carefully peel away foil. Lay back down. Cut away edges of dough to form a 14 x 9-inch rectangle. Measure and cut this rectangle into twenty-one 2 x 3-inch individual rectangles.
DECORATE with frosting, candies, sprinkles and sugars as desired. Allow frosting to harden slightly (about 30 minutes) before wrapping.
