Preheat the oven to 350° F and spray a 9 x 13-inch baking dish with nonstick cooking spray. 

Roll the pastry out and lay it in the bottom of the greased baking dish.

In a large bowl, use an electric hand whisk to blend the cream cheese, vanilla essence, and 1 cup of sugar together until soft and smooth. Spoon it all onto the pastry and spread it out until it is even.

Place the other pastry sheet over the cream cheese mix.

Pour the melted butter over the top. 

Mix the remaining sugar and cinnamon together and sprinkle evenly on top.

Place in the center of the preheated oven and bake for 25-30 minutes, until the pastry is puffed up and the sugar on top is brown and crackly. Allow it to cool and serve.
