Preheat the oven to 375° and spray 9x13 baking dish with cooking spray.
Unroll 1 can Crescent rolls (or 1 sheet rolled puff pastry) and place at the bottom of baking dish, seal the perforations.
Mix softened cream cheese, sugar and vanilla until well combined and spread onto dough.
Scatter fresh blueberries onto cream cheese.
Unroll second can Crescent rolls and spread over filling and seal the edges and perforations.
Brush with melted butter and sprinkle with sugar.
Bake for 25-30 minutes or until the top is golden brown.
I find it easier to press the seams of 4 triangles together on the counter then place it on top & seal the two halves together. I also let it cool about 20 mins on the counter then pop it in the freezer for another 20 mins, it's still warm but slices nicely & the guys like it a little bit warm.
