Spice up this year’s Valentine sugar cookies with cinnamon. These fun Red Hot Sugar Cookies start with a tender sugar cookie base that’s iced with a cinnamon frosting loaded with crushed Red Hot candies.
In a mixing bowl, whisk together powdered sugar and milk until smooth. Whisk in corn syrup. Stir in candies. Add more powdered sugar or milk to achieve a creamy, spreadable frosting.
