Scoop the chilled dough using a 1/4-cup measuring scoop. Divide the dough in half and create a well in one half. Place a ball of filling inside the well, then press the other half of the dough on top to seal. Roll into a ball to fully encase the filling.

Arrange the dough balls on the prepared baking sheets, spacing them about 2 inches apart. Bake for 11-13 minutes, until the tops are just set and the edges are lightly golden brown. Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Whisk together the powdered sugar, cinnamon, melted butter, and milk until smooth. Spoon the glaze over the cooled cookies, letting it spread to the edges. Allow the glaze to set for 15 minutes before serving.
