Preheat the oven to 400°F (204°C).
Unfold the puff pastry and sprinkle it with brown sugar and cinnamon. Spread to the edges with a brush or your hands.
Roll from the bottom up until you have a nice tight tube. Lightly dampen along the edge with water to create a seal.
Cut into slices about 3/4 inch thick. You should get about 12 to 14 pieces from 1 sheet of puff pastry.
Place each slice flat on a parchment-lined baking sheet.
Bake for 15 minutes or until golden brown and soft. Set aside for 3 to 5 minutes to rest. While resting, make the glaze.
Whisk the milk and powdered sugar in a saucepan. Then whisk in the remaining ingredients and place over low heat. (Add more milk if needed for a looser consistency. Add more cream cheese if needed for a tighter consistency.) Continue to whisk until fully combined and warmed throughout. Serve 1/2 cup per portion.
Serve cinnamon rolls with the warm glaze on the side for dipping. Enjoy with milk.
