Step 1

Preheat oven to 450 degrees F. Lightly coat a mini muffin tin with cooking spray.

Step 2

Unroll pie crust onto a cutting board or clean surface. Flatten dough to about 12 inches in diameter. Cut 24 2-inch circles out of the dough with a biscuit cutter, rerolling scraps if needed. Place the dough circles in the muffin tin cups, gently pressing on the bottom and sides. Prick the dough with a fork. Bake until lightly browned, 5 to 7 minutes. Remove from the oven.

Step 3

Add 1 teaspoon cranberry sauce to each cup, then top with a piece of Brie. Return to the oven and bake until the sauce is hot and the cheese has melted, about 5 minutes more. Let cool for 10 minutes. Sprinkle with chives, if desired, and serve warm.
