Preheat oven to 325°F.
To the bottom of a 9x16 baking tray, generously brush with melted butter. Add about half of the cinnamon sugar on the bottom evenly.
Add one sheet of crescent roll dough to cover the bottom.
Pour the cheesecake filling on top and spread evenly into one layer.
Add the second sheet of crescent roll dough to cover the cheesecake filling.
Brush generously with the melted butter and cover with the cinnamon sugar.
Bake for 30 minutes in the oven.
Once done, allow to come to room temperature on the counter first.
Then cover and transfer to the fridge to set overnight or at least for 6 hours.
After resting, cut into squares and serve with whipped cream or a drizzle of dulce de leche on top!
