Line 2 large baking sheets with parchment paper. Set aside.
Place dough on a floured surface. Divide into 4 pieces, 8 ounces each. Form each piece into a 12-inch log. Roll each piece into a 15-inch x 6-inch rectangle. Trim the edges as needed. Spread the cream cheese mixture on the dough to within 1-inch of the edges. Spread cinnamon/sugar mixture on the cream cheese to within 1-inch of the edges of the dough.
Starting at one of the long edges, roll the dough tightly into a 15-inch log; pinch seam to seal log. Place the rolled dough onto the prepared baking sheet, seam side down, and form the dough into a ring. Carefully place one end into other end; pinch to seal. Moisten the ends of the dough with a little water; pinch the two ends together to seal. Place small greased round container into center of ring. Repeat with remaining dough.
Cover with a cloth, and let rise in a warm place until doubled in size, about 1 hour to 1 hour and 30 minutes.
Preheat oven to 350°F. Bake in preheated oven until the tops are golden brown, about 20 minutes.
Mix the ingredients for the icing to make a smooth, but not thin icing.
Remove the cakes from the oven, and cool for about 10 minutes on a wire rack. While the cake is still warm, spread the icing on cake, allowing drips of icing to dribble down the sides and center of the cake. If using sprinkles, decorate while cake is still warm. Otherwise, decorate as desired. Yield: 4 "Chris" Kringle Cakes
