Lightly spray a baking pan with cooking spray.
Preheat oven to temperature on crescent rolls.
Unroll crescent roll dough onto prepared pan, sealing perforations.
Spread butter over dough.
In a bowl, add pear slices and pour cinnamon sugar over them. Toss to coat.
Spread pear slices evenly over dough.
Sprinkle brown sugar over pears.
Bake in oven until crescent dough is cooked through. (I followed baking time on can)
Once done, drizzle with icing & sprinkle with nuts if desired.
