01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large mixing bowl, cream softened butter, granulated sugar, and brown sugar until light and fluffy. Add egg and vanilla extract; beat until combined.
04 - Gradually mix dry ingredients into the creamed mixture, blending just until incorporated.
05 - In a separate bowl, beat cream cheese, powdered sugar, and vanilla extract until smooth.
06 - In a small bowl, combine melted butter, brown sugar, and ground cinnamon.
07 - Scoop 1 tablespoon of cookie dough and flatten into a disk. Place 1 teaspoon cheesecake filling in the center. Top with another tablespoon of dough and seal the edges. Roll gently to form a ball.
08 - Place dough balls on prepared baking sheets, spacing 2 inches apart. Use your thumb to make a small indent in the center of each ball.
09 - Drizzle about 1/2 teaspoon cinnamon sugar swirl into each indent.
10 - Bake for 11 to 13 minutes, or until edges are golden brown. Allow cookies to cool on the pan for 5 minutes, then transfer to a wire rack.
11 - For optional glaze, whisk powdered sugar, milk, and vanilla extract until smooth. Drizzle over cooled cookies if desired.
