Preheat the oven to 350 degrees. Prepare a 9x13 baking dish with nonstick cooking spray. In a mixing bowl, beat together 1 ½ cups cake mix, flour, yeast, and warm water until well blended.
Add the eggs and mix just until combined. Transfer the batter to the prepared baking dish and spread evenly across the bottom. Drop the pie filling a little at a time to create an even layer.
In a small bowl, stir together the remaining cake mix and melted butter. Crumble the mixture and sprinkle over the top of the cherry pie filling. Bake the coffee cake for 35 to 40 minutes.
Allow the coffee cake to cool on a wire rack until warm. In a small bowl, stir together the ingredients for the glaze. Spoon the glaze over the top of the coffee cake. Slice into bars and serve warm.
