Use a large #16 cookie scoop to make 2.7-ounce portions of dough. Flatten the ball of dough into a circle.
Add 1 level tablespoon of cream cheese filling to the center of the dough. Fold the sides of the dough up and around the cream cheese filling, sealing all the cracks. There may be some small cracks on the exterior of the dough, which is fine.
Roll the cookie balls in the cinnamon sugar until fully coated.
Place the balls of dough on the prepared baking sheets, leaving 2 inches between each (9 cookies will fit on a 12x17-inch cookie sheet slightly offset from each other).
Bake the cookies one cookie sheet at a time for 10 to 12 minutes or until the edges are just turning light brown. The centers should still be very soft and look slightly puffy and underdone. Remove from the oven and allow them to cool for 10 minutes on the pan before transferring them to a wire rack to cool completely.
(OPTIONAL) Once cooled, melt the ½ cup white chocolate melting wafers in a microwave-safe bowl at 30-second intervals, stirring after each one, until fully melted. Transfer to a small piping bag or Ziploc bag with the corner cut off, then drizzle over the top of the cookies and let set. If adding sprinkles, make sure to add them before the chocolate sets.
Let cookies sit at room temperature for at least 2 hours before enjoying. This lets the cookie finish cooking internally and set up properly.
