Put the flour, dates, cinnamon, cream of tartar, baking soda, and salt into a food processor. Process until the dates have been chopped finely and incorporated throughout the ingredients, about 1 minute.
1 cup whole wheat flour, 1 cup pitted medjool dates, 1 tsp ground cinnamon, ¾ tsp cream of tartar, ¼ tsp baking soda, ¼ tsp kosher salt
In a large bowl, whisk the melted coconut oil, the egg, and vanilla together until well combined.
¼ cup melted coconut oil, 1 TBS vanilla extract, 1 whole egg
Add the flour mixture to the wet ingredients. Mix until there are no more dry patches of flour.
Cover the bowl and chill the dough for 15 minutes.
Place a rack in the middle position in the oven. Heat the oven to 350℉.
Make the cookie coating by combining cinnamon and sugar in a bowl.
2 tsp ground cinnamon, 1 TBS coconut sugar
Divide the dough into 12 dough balls (about 32 grams each). Roll each into a ball, then slightly flatten between your palms. Place into the bowl of cinnamon sugar and press into the coating until flattened into a 2" diameter disc. Flip the cookie dough disc over and coat the other side. Place on a lined cookie sheet. Repeat the process with each dough ball.
Bake in the oven until jut set in the center, about 10 minutes.
Take out of the oven, let cool 5 minutes on the tray then place on a rack to finish cooling. Enjoy!
