Yes, and it's so easy to make an amazing lemon glaze for donuts as well. Just combine (whisk works great) 2 1/2 cups of powdered sugar and 1/4 cup of lemon juice until smooth and creamy. Dip warm donut tops right into the glaze and set them aside to set. Done!  If you prefer a plain glaze, combine 2 1/2 cups of powdered sugar and 1/4th cup of milk until smooth. It's always best to slowly add milk until consistency is reached that you want.
