Preheat oven to 375*F. Grease cookie sheet and set aside.
Arrange crescent rolls in a circle, short ends together and overlapping slightly, long point outward.
Combine blackberries, cream cheese, and blackberry jam in a small bowl. Mix well with a spoon.
Arrange blackberry mixture, one tablespoon at a time, on the crescent rolls where they overlap in a ring.
Wrap long points of the crescent rolls around the blackberry mixture, and tuck under the center.
Bake for about 18 minutes, or until golden brown.
Serve for breakfast, or drizzle with a glaze and serve for dessert!
Either way, Enjoy!
