Melt remaining butter. Mix sugar and cinnamon in shallow dish. Separate dough into 20 biscuits; press each to 1/4-inch thickness. Roll cream cheese cubes in cinnamon sugar mixture until evenly coated on all sides. Place 1 cream cheese cube in centre of each biscuit circle; gather up sides of dough to enclose filling. Press edges of dough together to seal; roll into ball. Dip top of each ball in remaining butter, then in cinnamon sugar.
