In a medium saucepan, place cranberries, orange juice, cinnamon, and brown sugar. Bring to a simmer and reduce to low heat, stirring frequently, until thickened.
Slice the French bread and place on a rimmed baking sheet.
Place slices of brie onto each piece of bread, then bake for 10-15 minutes until the bread is toasted and the brie is melted.
When the cranberry sauce has thickened, spoon it onto the pieces of bread.
Serve immediately. Enjoy!
