Optional - sprinklescandy canes, mini chocolate chips, etc.
Preheat oven to 350 degrees.
Using a handheld mixer, blend together the butter and the sugar until light and fluffy.
Add the flour and use a spatula to fold the flour into the butter mixture.
Once fully incorporated, wrap the dough in plastic wrap and refrigerate for 30 minutes.
With a rolling pin, roll out the dough until a 1/4 inch thickness has been achieved.
Cut into desired shapes.
Add toppings if desired, and bake for 15 minutes.
Allow cookie to completely cool before adding icing if you plan to do just that.
You will note that I decided to add sprinkles to the dough as I was mixing it. After I rolled out the dough, I added a few more on top, and just slightly pressed them into the dough so they wouldn't roll off.
