Separate dough into 8 rolls; set icing aside. With palm of your hand, press down 1 roll to flatten slightly (for bunny’s head). Place second roll flat on work surface; with sharp knife, cut down middle of roll almost to the edge, but not all the way. Carefully open roll to create 2 halves, leaving bottom of roll connected. Press and firmly pinch connected part of roll to top of flattened whole cinnamon roll. Shape cut halves into floppy bunny ears. Place bunny on cookie sheet. Repeat with remaining 6 rolls to make 3 more bunnies.
