Cinnamon Nut Chocolate Spirals

Combine flour and salt in small bowl; set aside. Beat 1/2 cup sugar and 1/3 cup butter in large bowl with electric mixer at medium speed until light and fluffy. Add egg; beat until blended. Gradually add flour mixture, beating until well blended. Dough will be stiff. (If necessary, knead dough by hand until it holds together.)

Roll out dough between 2 sheets of waxed paper into 12X10-inch rectangle. Remove waxed paper from top of rectangle.

Combine chocolate chips, walnuts, remaining 1/4 cup sugar and cinnamon in medium bowl. Melt remaining 3 tablespoons butter; stir into chocolate chip mixture. (Chips will partially melt.) Spread mixture evenly over dough leaving 1/2-inch border on long edges.

Using bottom sheet of waxed paper as guide and starting at long side, tightly roll up dough jelly-roll style, removing waxed paper as you roll. Wrap in plastic wrap; refrigerate 30 minutes to 1 hour.

Preheat oven to 350°F. Lightly grease cookie sheets. Unwrap dough. Cut log into 1/2-inch slices. Place slices 2 inches apart on prepared cookie sheets.

Bake 14 minutes or until edges are light golden brown. Remove to wire racks to cool completely.
