Preheat the oven to 375 degrees. Place the squash halves, cut side down, on a baking sheet and roast for 30-40 minutes or until fork-tender.
Scoop out the innards into a bowl and add butter, syrup, and salt. Mash with a potato masher OR puree with a food processor.
Spread into a small casserole dish and sprinkle with cinnamon. Keep warm in the oven until serving, then serve by the spoonful!
