1Heat oven to 375°F. In small bowl, mix sugar and cinnamon; set aside. Unroll dough; separate into 4 rectangles. Press each to 6x4-inch rectangle, pressing perforations to seal.
2Brush tops of 2 rectangles with some of the melted butter; sprinkle with about half of the sugar mixture. Top each with remaining rectangle; press edges lightly. Brush tops with melted butter.
3With sharp knife or pizza cutter, cut each rectangle stack lengthwise into 6 strips. Twist each strip 3 times; place on ungreased cookie sheet.
4Bake 9 to 11 minutes or until golden brown and crisp. Brush tops with any remaining melted butter; sprinkle with remaining sugar mixture.
