Remove one sheet of puff pastry from freezer and thaw according to package instructions.
Preheat oven to 350 degrees. Line a baking sheet with parchement paper.
Mix butter, garlic, parsley, salt and pepper and cheeses together. Set aside.
Cut pastry in half. Create a border around the edge of the pastry by scoring the pastry with a knife about inch in from the edge of the pastry. I only score the pastry about half way through the thickness of the pastry.
Spread half of the butter mixture over each piece of puff pastry on the inside of the scored border.
Bake for 8-10 minutes. Then move rack to broil for about 2 minutes. Watch carefully so it doesn't burn.
Let cool for about 5 minutes then cut into thick slices.
