Preheat oven to 375. Grease a 9x13 baking dish. Pour the can of pie filling into baking dish, spreading evenly. Next sprinkle cake mix on top of pie filling, gently spreading across the top evenly (do not stir). Finally, drizzle melted butter across the top of the cake mix. Last but not least, drag a knife in zig zags through the cobbler to combine the ingredients gently. Bake at 375 for 30 minutes or until golden brown.
If you are using sliced fruit in juices instead of pie filling, increase baking time to 40-45 minutes, or until golden brown.
