01 - Preheat the oven to 350°F. Lightly grease a 24-cup mini muffin tin with nonstick spray or melted butter.
02 - Lay 1 sheet of phyllo pastry on a clean surface; keep remaining sheets covered with a damp towel. Brush the sheet lightly with melted butter, then layer a second sheet on top. Repeat until you have 4 layered sheets. Cut the stack into 6 equal squares. Press each square gently into 6 cups of the prepared muffin tin. Repeat with the remaining sheets to fill all cups.
03 - Place one piece of Brie into each phyllo cup. Evenly distribute chopped pecans over the cheese.
04 - Bake for 12–15 minutes, or until the phyllo is golden brown and crisp, and the Brie is melted.
05 - Remove from oven and drizzle each cup with maple syrup. Serve warm.
