Mini Blueberry Breakfast Loaf

Preheat oven to 350 degrees. Grease 4 mini loaf pans and set aside. In a large mixing bowl, combine sour cream, pie filling, and eggs with a wooden spoon. Add box cake mix and stir gently until just moistened. Scoop batter into pans about halfway full. Sprinkle tops of batter with granulated sugar. Bake for 25 minutes or until toothpick inserted in the center comes out clean. Let loaves cool in pans for 5 minutes, then transfer to a wire rack to finish cooling. Slice and serve! Refrigerate leftovers (if any).
