In a large mixing bowl, cream together the dairy-free butter and sugar until light and fluffy. Mix in the eggs and vanilla until well combined.
Add the flour, cream of tartar, baking soda, and salt to the bowl, then stir everything together to mix well.
Chill the dough for 30 minutes in the refrigerator.
Meanwhile, preheat the oven to 350 degrees F and prepare three baking sheets with parchment paper. Also, in a small bowl, combine the sugar and cinnamon that you’ll use for rolling.
When the chill time is up, remove the dough from the refrigerator. Take heaping tablespoons of dough, roll into a ball, and roll in the cinnamon sugar mixture. Place the cookie dough balls onto the prepared baking sheets.
Bake the cookies at 350 degrees F for 10-12 minutes, or until the cookies are flat and cooked through. Let cool then enjoy!
