Preheat the oven to 350 degrees F and place the cored apples in a loaf pan lined with foil.
Combine the sugar and cinnamon and funnel half the mixture into each apple core. Drape two bacon slices in an X shape over the top of each apple.
Bake 10-15 minutes or until the apples are fork tender and the bacon is crispy. The exact cooking time will vary depending on how large your apples are and how thick your slices of bacon.
