Combine the apples, butter, honey and salt in small roasting dish. Roast in a preheated 400*F oven for about 30 minutes until golden and soft - stirring every 10 minutes. You want the juices reduced. When done, set aside.
Whisk the eggs, cream, sugar and vanilla in large bowl. Dip the bread, making sure thoroughly soaked. Over medium high heat melt 1 tbsp butter in skillet and fry two pieces of bread at a time. When one side is golden, flip over continue cooking until that side is golden as well. Place 3 pieces of brie, half the apples and walnuts on one slice. Top with the other piece of bread - it’s like you are making a French toast sandwich! Reduce heat and flip over once more. Cook until the brie is melted. Slide off to a baking dish and keep warm in low oven while you repeat with the rest of the ingredients. Serve warm with Birch syrup and more butter, if you like. Serves 2.
