These glazed gingerbread donuts are the perfect bite. If you don't love glaze, though, that's okay. Feel free to swap it for a cinnamon sugar mixture with the sugar and cinnamon having a 1:4 ratio. For example, 1 cup of granulated sugar to 1/4 cup of ground cinnamon. You'll want to dip the donuts in melted butter first. Place the cinnamon sugar mixture into a medium bowl, then dip each side of the donuts into the cinnamon sugar mixture.
