Instructions

1. Preheat oven to 375 degrees F.
2. Grease and line an 8 x 8 inch square baking pan with a sheet of parchment paper long enough so that the flaps fold down the sides of the pan.
3. Combine the 3 tablespoons of sugar and cinnamon in a small bowl, set aside.
4. In a large mixing bowl, beat coconut oil, 1 cup sugar, baking soda and cream of tartar, scraping down the sides of the bowl, as needed. Add egg and vanilla extract and beat until combined. Add flour in gradually, scraping down the sides as needed. The dough will be sticky and you might need to stir in the remaining flour. 
5. Press the dough into the prepared baking pan, sprinkle the top evenly with the prepared cinnamon-sugar mixture. Bake for 10-12 minutes. To check for doneness, insert a knife into the middle, the knife should come out clean. When it's done, allow to cool for 5-10 minutes in the pan. You can transfer to a wire rack using the parchment paper to pull it out of the baking pan. Cut into 9 squares (or smaller). Enjoy!
