In a small bowl, combine the softened cream cheese and ground cinnamon. Mix until smooth.
In a large mixing bowl, beat the softened butter until creamy.
Add the brown sugar and mix until well combined.
Continue mixing until the mixture is smooth and fluffy.
Add the cream cheese mixture and whisk until fully incorporated.
Add the flour, baking powder, and salt.
Mix until a soft dough forms.
Gather the dough together and shape it into a smooth ball.
Roll the dough into a rectangle on a lightly floured surface.
Brush the melted butter over the dough, then sprinkle evenly with the brown sugar and cinnamon mixture.
Roll the dough tightly into a log.
Chill the log for at least 1 hour or until firm.
Slice the chilled log into even rounds about ½ inch thick.
Arrange the cookie slices on a lined baking sheet, leaving space between each cookie.
Bake at 350°F (175°C) for 10–12 minutes, or until lightly golden around the edges.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Serve the cookies once cooled and enjoy.
