In a stand mixer, add the stick of butter plus 2/3 cups of white sugar and cream them together (do not whip).
Add in the vanilla extract and apple cider vinegar. Mix in (use mix setting).
Add in the flour, cream of tartar, baking soda, 1 and 1/4 tsp cinnamon, and salt. Mix in by hand, not using the electric mixer. Mix until a crumbly dough is formed.
Add in almond milk and gently mix until it resembles a traditional cookie dough feel.
In a flat pie dish, mix in the remainder of your sugar and cinnamon. Prep a baking sheet lined with parchment paper.
Roll your cookie dough into balls and then roll each ball in the cinnamon sugar mixture. Place onto your parchment lined cookie sheet. Sprinkle the cookie dough balls with whatever cinnamon sugar is left at the end.
