Heat the oven to 350° and cover your baking sheet with parchment paper or non-stick coating.
Mix the flour, baking powder, salt, and cream of tartar together.
In a second bowl, mix the coconut oil, maple syrup, and vanilla.
Combine the wet and dry ingredients and whisk thoroughly.
In a third bowl, combine the sugar and cinnamon.
Take two tablespoons of dough and form them into a ball. Roll the balls in the cinnamon sugar and set them on the baking sheet.
Gently flatten each one before finally placing the sheet in the oven.
Cook for 10-12 minutes, until they turn golden brown.
