Pre-heat oven to 375 degrees and line 2 cookie sheets with parchment paper; set aside. Gather all your ingredients together.
Make the topping: mix erythritol and cinnamon together in a small bowl and set aside.
Cream softened butter with electric mixer for about 1-2 minutes until the butter becomes soft and fluffy, then add in the 1 1/3 cup erythritol.
Next add in the egg and vanilla, mix on medium speed until fully combined, fluffy & light in color.
In a separate bowl combine all of your dry ingredients together: flour, cream of tartar, baking soda, 2 1/2 tsp. cinnamon, and salt.
With the mixer on low, slowly add in the dry ingredients to the wet ingredients. The dough gets quite thick and may need to be mixed by hand towards the end.
Take 1 tbsp. of dough and roll it into a ball. Roll the ball in the cinnamon-erythritol topping mixture & sprinkle extra topping if desired for more flavour.
Bake cookies for 8-10 minutes. Allow cookies to cool on the cookie sheets for 10 minutes before transferring them to a wire rack.
