Preheat oven to 350℉. Combine ¼ cup of sugar and cinnamon in a small bowl. Set aside.
Unroll one tube of the crescent rolls and press it into the bottom of a 9x13-inch baking dish*.
In a large bowl beat the cream cheese, ¾ cup of sugar, and vanilla with a hand mixer until light and fluffy.
Spread the cream cheese mixture in an even layer over the dough in the baking dish.
Unroll the second tube of crescent rolls and lay it over the cream cheese mixture.
Melt the butter and pour it overtop, using a brush to ensure everything is covered. Sprinkle cinnamon sugar overtop.
Bake for 30-35 minutes or until bars are set. Allow to cool on a baking rack for 30 minutes and then transfer to the fridge, uncovered, to cool for at least an hour before cutting.
Notes
*A glass baking dish will cook the cream cheese squares more evenly and allow them to crisp up more on the bottom.
