Heat oven to 400ºF. In medium bowl, stir together fruit mixture ingredients; let stand 10 minutes to allow sugar to pull juices from peaches. Transfer to ungreased 8-inch square (2-quart) glass baking dish. Bake uncovered about 10 minutes or until fruit is bubbling. Remove from oven; stir. Bake 10 to 12 minutes longer or until bubbly around edges (fruit must be hot in middle so biscuit topping bakes completely).
