Preheat your Grill to 350 degrees F.
In a bowl, combine flour, sugar, baking powder, salt and mix to incorporate. Stir in butter and milk and mix until combined. In a cast iron pan, dump in cherry pie filling and pile on the prepared topping to cover.
Place in your Grill and bake for about 45 minutes, or until the topping is golden brown.
Let cool for a couple minutes and serve with ice cream.
