Preheat your oven to 375°F and grease a 24-count mini muffin tin with cooking spray. Set it aside.
In a small saucepan over medium heat, combine the cranberry sauce, orange juice, orange zest, sugar, and cinnamon. Bring the mixture to a boil, then reduce to a simmer for about 5 minutes, or until the sauce thickens up nicely.
Roll out the crescent dough onto a piece of parchment paper or a lightly floured surface. Cut the dough into 24 even squares. Place each piece into a slot of the muffin tin.
Cut the Brie into small pieces and place one in each dough-filled muffin cup.
Spoon about 1 teaspoon of your cranberry sauce on top of each piece of Brie.
Sprinkle a pinch of fresh thyme on each bite for an extra pop of flavor.
Pop the muffin tin in the oven and bake for 10 minutes, or until the crescent dough is golden and the Brie is melted.
