Pour the glaze in a shallow bowl that’s larger than the donuts. If you are icing the tops only, then hold the donut upside down over the bowl, dip and then tap your hands to allow excess icing to drip back into the bowl. Place the iced donut on a cooling rack and allow the glaze to set. If you are icing the whole donut, submerge the donut fully in the bowl of glaze and use a large fork to quickly remove the donut from the bowl and transfer to a cooling rack (with a sheet of wax paper lined underneath it) and allow excess to drip off onto the wax paper.
