Preheat oven to 350 degrees F. Lightly grease a 10" cast iron skillet or a 9x9 baking pan, set aside.
FRUIT FILLING: In a large bowl combine all the ingredients for the fruit filling and gently toss to combine. Spoon into prepared pan.
BISCUIT TOPPING: In the same bowl you mixed your fruit in combine the flour, sugar, baking powder and salt. Using a pastry blender or 2 knives, cut in the butter until it resembles coarse crumbs. Stir in the cream just until combined. Drop in spoonfuls over the fruit. Bake for 35-40 minutes or until topping is lightly browned and fruit is bubbly. Let cool 10-15 minutes before serving.
