This is really easy and delicious. Slice the squash in half lengthwise, scoop out the seeds with a spoon, and place the pieces cut side up in a baking dish. Put a small pat of butter inside each one, and sprinkle with brown sugar or a drizzle of maple syrup. Bake for about an hour at 450, until the squash is very soft and the top is nicely browned. Eat with a spoon right out of the shell. Yum!
