Spinach Artichoke Cups

Preheat oven to 375°. Grease a mini muffin tin with cooking spray. In a large bowl, combine spinach, artichokes, cream cheese, sour  cream, 1 cup mozzarella, Parmesan, and garlic. Season with salt and pepper.  On a lightly floured surface, roll out crescent dough, pinching seams together. Cut into 24 squares. Place squares into muffin tin slots and spoon 1 tablespoon of dip into the dough. Top with remaining mozzarella. Bake until pastry is golden and cheese is melted, about 15 minutes.
