Preheat your oven to 350°F (175°C).
Place the Brie cheese on a baking dish or a small oven-safe skillet.
Drizzle the honey evenly over the top of the Brie.
Sprinkle the chopped nuts over the honey, ensuring they are evenly distributed.
If using, add the fresh rosemary and cinnamon on top of the nuts for extra flavor.
Bake in the preheated oven for about 10-15 minutes, or until the Brie is soft and gooey.
Remove from the oven and let it cool for a couple of minutes before serving.
Serve warm with slices of French baguette or your choice of crackers.
