Line three baking sheets with parchment paper and preheat your oven to 350°F (180°C).
Cream together the unsalted butter, cream cheese, granulated sugar, brown sugar, and molasses on low speed for about three minutes until light and fluffy.
Add in one large egg, an additional egg yolk, and vanilla extract to your creamed mixture, mixing well after each addition.
Gradually mix in all-purpose flour, baking powder, cream of tartar, and fine sea salt until just combined to form a thick cookie dough.
Combine cane granulated sugar with ground cinnamon for rolling. Scoop about two tablespoons of cookie dough, roll it in the cinnamon-sugar mixture, and place it on the prepared baking sheet, creating an indent in each cookie's center.
Fill each indent with half a tablespoon of Musselman’s apple butter and sprinkle turbinado sugar on top. Bake for eight to twelve minutes until edges are set; let them cool completely before indulging.
