Add the white sugar, brown sugar, and room temperature butter to the bowl of a stand mixer fitted with the paddle attachment and cream the mixture for 2-3 minutes, until smooth.
Add the apple butter, egg, and vanilla and beat again until well combined, scraping the sides of the bowl if needed.
Add the dry ingredients and mix on low until the dough is combined and becomes one ball of dough.
Cover the bowl and place in the fridge for 1 hour. Preheat oven to 350℉ and line a large baking sheet with parchment paper.
Stir together the cinnamon and sugar in a shallow bowl and set aside.
Divide the cookie dough into 18 equal balls (about 3 tbsp dough each), and roll in the cinnamon sugar mixture.
Place the cookies on the prepared baking sheet in an even layer with at least 1 inch of space between each one, and bake in the preheated oven for 13-15 minutes, or until crackly on top and slightly browned.
Allow the cookies to cool for 5 minutes on the baking sheet, then transfer to a cooling rack to cool completely. Store at room temperature in an airtight container for up to 3 days.
