In large bowl, beat filling ingredients with whisk until thoroughly combined. Pour into crust-lined pan. Bake 20 minutes. Reduce oven temperature to 400°F. If necessary, cover crust edge with strips of foil to prevent excessive browning. Bake 15 to 20 minutes longer or until knife inserted in center comes out clean. Cool completely on cooling rack, about 1 hour. Refrigerate at least 1 hour or until cold.
