Simmer cranberries, sugar, and orange zest in a saucepan for 8 minutes until thick and glossy.
Preheat oven to 375°F. Cut puff pastry into 12 squares and press into a mini muffin tin.
Brush pastry with egg wash, add a brie cube, and top with a teaspoon of cranberry mixture.
Bake for 12 minutes or until golden and puffed.
Cool slightly, then add rosemary sprigs as festive 'trees.' Drizzle with honey before serving.
