Preheat oven to 375F. Line a large, rimmed baking pan with parchment paper.
If needed, create a slit in each medjool date to remove the stem and pit.
Stuff with a small slice of brie and walnut. Press in the date edges to help seal in the fillings.
Wrap with half a slice of bacon, then place seam-side down on the baking pan. If needed, you can use a toothpick to keep the bacon in place.
Brush the bacon with maple syrup.
Bake for 10-12 minutes, until the bacon is cooked through. Broil 30 seconds to 1 minute to help crispen it on top.
(Optional) Drizzle with more maple syrup (heated to help thicken it into a glaze) or hot honey.
Garnish with fresh thyme to serve warm!
