In a small saucepan, melt butter. Add orange juice, bacon bits, walnuts, apple, cinnamon and 3 tablespoons brown sugar. Cook over medium-high heat, stirring frequently, until sugar has dissolved and apples begin to brown, 3-5 minutes. Remove from heat. Stir in orange zest.
Unroll crescent rolls and pinch together seams to create 1 large sheet with each package of dough. Cut each rectangle into 12 squares.
Cut brie into 24 pieces and place in the center of the dough square. Top with apple walnut mixture and a pinch of brown sugar. Bring edges of the dough square to the center and pinch to create a seal.
Bake for 10 minutes or until golden brown.
Garnish each bite with a sugared cranberry for an unexpected burst of flavor.
