Place chilled brie round on parchment paper and cut parchment paper into a circle enough to cover the brie. Place the parchment paper circle into a baking dish, and place brie wheel onto the parchment paper.
Do NOT cut the top off of the brie round, you need the brie to hold its shape for this recipe. Set baking dish aside.
Add the berries to a small sized baking dish (a pie dish works fine), sprinkle the berries with sugar and coat in coconut oil, sprinkle with rosemary and gently mix everything to make sure all the berries are covered in coconut oil and sugar.
Transfer the cheese and the berries into the preheated oven and bake for 15 minutes.
Remove baking dishes from oven, gently transfer baked brie to a serving plate, spoon the berry mixture on top of the baked brie, garnish with fresh rosemary.
Serve immediately with crackers, sliced apples, fresh warm bread, or banana chips.
