Start by patting your cherries with a paper towel. You’ll want them fairly dry before adding them in. Preheat your oven to 325 degrees.
Whisk together your flour and sugar. Using a pastry cutter, cut in the cold butter. Stir in the vanilla and cherries. You now have what looks like a failed recipe.
Wash your hands and get kneading. Knead that dough until it forms a solid ball. Form 1 inch balls and place on a cookie sheet. Dip the bottom of a drinking glass into sugar and gently press each cookie.
Bake for 10-12 minutes. Drizzle with chocolate if desired.
