Preheat oven to 350 degrees. Place the brie round on foil or parchment paper, then set on a baking sheet. Bake for 10 minutes.

Meanwhile, heat a sauce pan over medium high heat. Melt the butter and toast the walnuts for 1-2 minutes, until fragrant. Add the brown sugar and diced apple and cook for about 5 minutes, until apples are tender. Add the cranberries, a dash of cinnamon, and a pinch of salt.

Remove the hot brie from the oven and pour the sautéed apple mixture over top. Serve with crackers or toasted baguette rounds.
