Preheat your oven to 375°F. Grease a mini muffin tin with cooking spray. On a lightly floured surface, roll out the crescent dough and pinch the seams together. Cut the dough into 24 squares and press each square into the prepared muffin cups.

Cut Brie into small pieces and place a piece inside each square of dough. Top with a spoonful of cranberry sauce, a few pecans, and a piece of rosemary.

Bake the bites in the preheated oven for about 15 minutes or until the pastry is golden brown.
