Kick the tires and light the fires to 350.Cream the butter and sugar together well, then add in your eggs.
Once the eggs are completely mixed in, add in your vanilla. Shred an entire lemon onto the mix, which means taking a lemon, and grating all the yellow part off. This is really what adds the lemon flavor, don't skimp on the lemon.
Whisk your dry ingredients together
.Add the dry in slowly to the wet mixture, little by little.
Stir the dough until combined.
You can either cover the dough or put it into a plastic bag and refrigerate it for at least an hour
For the Deathly Hallows Cookies, roll out the cookies to your desired thickness (these make great thick cookies!) and cut out a circle with a glass or a cookie cutter.
Bake in a 350 degree oven until the edges just barely start to get brown, about 6-8 minutes. Let them cool on racks and mix up your icing.
Sugar Cookie Icing
Mix the ingredients together.
The ingredients listed are the base for the icing, in order to get thinner icing I added a little more milk until I could dip my cookies into the icing, and let them drip off, getting this beautiful glazed coating below.
Do NOT put in more corn syrup, it will never harden and set properly.
Add milk very little by little until you get the consistency you need.
Decorate the cookies with the icing, letting them harden overnight is best! The icing needs to set.
