Heat oven to 375°F. Lightly spray 4 medium ramekins or tart pans with cooking spray.
Separate dough into 8 biscuits; cut each into quarters. In small bowl, mix sugar and cinnamon. Dip each biscuit piece into melted butter; coat each with sugar-cinnamon mixture. Place in medium bowl.
Add blueberries to biscuit pieces in bowl. Using large spoon, transfer biscuit-blueberry mixture evenly to ramekins. Top each evenly with cubes of cold butter; drizzle each with 2 tablespoons syrup.
Bake 12 to 15 minutes or until dark golden brown. Serve with additional butter or syrup.
