Line a baking sheet with parchment paper and preheat oven to 375°F.
Unroll the crescent roll dough and separate it into triangles.
In a small mixing bowl, mix the butter with the brown sugar and the cinnamon. Spread about one tablespoon of the mixture onto each triangle. It should be a light covering. Roll the triangles up into crescent shapes and place them on the prepared baking sheet.
Bake in the oven for 12 minutes, then remove from the oven to cool slightly.
In another small mixing bowl, mix the water and powdered sugar. If you find the icing to be too runny, add more sugar. If it’s too stiff, add more water. Drizzle the icing over each cinnamon crescent roll after they have cooled.
Serve immediately.
Notes
Make them ahead of time! You can prepare the rolls up to the point of baking and store them in the refrigerator. When you're ready to enjoy them, bake as directed.
Store any leftover Cinnamon Crescent Rolls in an airtight container at room temperature for up to 2 days. For longer storage, you can refrigerate them for up to a week.
You can freeze the rolls either before or after baking. If freezing before, place them on a baking sheet until frozen, and then transfer to a zip-top bag. Bake straight from the freezer, adding a few extra minutes to the baking time. If freezing after baking, allow them to cool completely before placing them in an airtight container.
To maintain the best texture and flavor, reheat the rolls in a preheated 350°F oven for about 5-7 minutes. Microwaving is also an option, but they might turn a bit chewy.
Try baking them in the air fryer! Line a basket with parchment paper and preheat the air fryer to 300°F. Place the crescent rolls in the basket (work in batches if necessary) and cook for 5 minutes. Carefully flip the rolls over and continue to cook for an additional 5 minutes or until golden brown and cooked through.
