These don't need a glaze, but if you want one: Whisk together 1 cup powdered sugar (sifted), 1 Tablespoon melted unsalted butter or coconut butter, a pinch of salt and 1-2 Tablespoons water or plant milk until completely smooth. I transferred the glaze to a ziploc bag and snipped a very tiny bit off one corner and squeezed the glaze through.
