Prepare the Cheesecake Filling: In a medium-sized bowl, mix cream cheese, powdered sugar, vanilla extract, and a pinch of salt until smooth. Chill in the refrigerator while preparing the dough.

Make the Cookie Dough: In a separate large bowl, whisk together flour, baking powder, salt, and cinnamon. In another bowl, cream together the butter and sugar until light and fluffy. Add the egg and vanilla extract, mixing until well combined. Gradually add dry ingredients to the wet mixture and stir until dough forms.

Form the Cookies: Roll dough into 1-inch balls and create a small indentation in the center of each. Spoon in a small amount of cheesecake filling and seal the dough around it, rolling it back into a ball.

Bake: Preheat oven to 350°F (175°C). Place cookies on a parchment-lined baking sheet and bake for 10-12 minutes, or until the edges are golden.

Coat with Cinnamon-Sugar: Immediately after baking, roll cookies in the cinnamon-sugar mixture while they are still warm.
