First, make the apple cider reduction. To do this, add the cup of apple cider to a pot and let simmer until about 3 tablespoons remain. This will take about 20-25 minutes. Then, let cool for about 15 minutes before adding it into the cookie dough.
Once you've made the apple cider reduction and let it cool, then you can start making the cookie dough. To start, preheat oven to 350 degrees. Then, line a baking sheet with parchment paper.
Using an electric mixer with the paddle attachment, beat the butter, sugar, and brown sugar together until light and fluffy. About 2-3 minutes.
After that, beat in the egg and the cooled cider reduction.
In a separate bowl, sift together the salt, flour, cream of tarter, and baking soda. Gradually beat into butter mixture.
In a small bowl, mix together all the coating ingredients and set aside. Scoop your cookie dough into 1 inch balls and then roll throughly in the sugar coating mixture.
Place cookie dough balls on prepared baking sheet, leaving room in between. These cookies do spread a little when baking.
Bake for 10-12 minutes, or until gold brown. Then, let cookies cool on wire rack before enjoying.
Store leftover cookie in an airtight container for up to 5 days.
