Heat oven to 375°F. Separate dough into 8 biscuits. Make 5 (3/4-inch-deep) cuts evenly around outside edge of each biscuit to resemble flower petals. Place each biscuit flower on ungreased large cookie sheet. (If biscuits are uneven, flatten slightly to make tops even.)
In small bowl, combine sugar and cinnamon; mix well. Sprinkle sugar mixture over biscuits. With thumb, make deep indentation in center of each biscuit. Fill each with scant teaspoon jelly.
Bake at 375°F. for 11 to 17 minutes or until golden brown. Serve warm.
