1. Preheat oven to 425°.
2. Cut squash horizontally into 4 (1/2-inch-thick) slices. Discard seeds, membranes, and any remaining squash. Place squash on a jelly-roll pan lined with foil.
3. Combine syrup and next 3 ingredients in a small saucepan over medium heat, and cook until butter melts. Brush 1 side of each slice of squash with syrup mixture. Bake at 425° for 15 minutes. Turn squash over, and brush with remaining glaze. Bake an additional 15 minutes or until tender.
