Preheat oven to 350 degrees. Grease the bottom and sides of a 9x13 casserole dish
In a large mixing bowl, combine cream cheese with sour cream, eggs, vanilla extract, sweetened condensed milk, sugar and cinnamon.
Use a hand mixer to mix well until smooth and no chunks remain.
Roll out one can of crescent dough to approximately match the size of the baking dish. Lay it into the bottom of the dish, pressing it to evenly cover the bottom. It’s ok if it doesn’t look perfect, it will be covered.
Sprinkle the crescent dough with an even coating of cinnamon-sugar to cover the dough.
Pour in the cheesecake filling. Repeat the same process with the dough, laying it on top the cheesecake. Work gently as to not make the dough sink. It doesn’t need to look perfect.
Sprinkle the entire top of the cheesecake with remaining cinnamon to coat the top.
Bake for 40-45 minutes. A toothpick inserted in the center comes out clean indicates its fully cooked.
Place cheesecake on top of a cooling rack or stove to allow heat to escape from under the dish, cool about 1 hour,. Cover tightly and refrigerate for 8 hours before serving (ideally overnight). Cheesecake is better the second day, so make ahead if possible.
