Preheat oven to 400 degrees. Lightly spray a 2-quart casserole dish with cooking spray and set aside. In a small saucepan melt 2 Tablespoons butter over medium heat and which in the flour, salt and pepper. Add the whipping cream and stir for about 2 minutes until it starts to thicken. Add ¼ cup parmesan cheese.
Arrange half of the zucchini in the prepared casserole dish overlapping each other. Spread half of the sauce on top followed by ½ cup mozzarella cheese. Repeat with another layer of zucchini and sauce topped with mozzarella cheese and remaining parmesan cheese.
Bake for 25 minutes or until the zucchini are fork tender and the top is starting to brown. Sprinkle with chives before serving.
