Preheat oven to 350 degrees
Cream together butter, sugar, salt, and cider packets together until light and creamy (about 2 minutes). Add the egg, and mix until incorporated. Mix in the vanilla. Add flour, baking soda, baking powder, and cinnamon. Mix until just combined. Place dough in the fridge for 30 minutes.
Scoop small balls of dough onto a baking sheet (about golf ball size). Bake for 10 minutes. Remove from oven and allow to cool for a couple minutes before removing to a wire rack.
Meanwhile you can make the glaze. Combine all the ingredients in a bowl, and whisk until smooth. You can adjust the sugar and juice amounts to get a thin and drizzle-able consistency. Using a spoon, drizzle over the cookies. Allow to cool and the glaze to completely harden before serving.
