Roll out crescent dough on a lightly floured surface.
Pinch together seams and cut into 24 squares. Place squares into greased mini muffin tin slots.
Chop brie into small pieces and place inside the crescent dough. Top with a spoonful of cranberry sauce, chopped pecans, and one small sprig of rosemary.
Bake for 15 minutes, or until golden.
