Place a steamer insert into a saucepan and fill with water to just below the bottom of the steamer. Bring water to a boil. Add carrots, cover, and steam until tender, about 15 minutes.
While carrots are steaming, melt butter in a saucepan over low heat. Combine with honey and cornstarch.
Pour glaze over cooked carrots and toss to coat. Serve immediately.
