Preheat oven to 400°F and spray a mini muffin pan with non-stick cooking spray. You'll need one pan with 24 cups, or two small pans with 12 cups.
Pour the cornbread mixture into each of the 24 wells of the muffin tins, leaving a little room at the top so it won't overflow when you put a hot dog piece inside.
Place one piece of hot dog in the center of each muffin and press down about halfway into the batter. Bake for 9-12 minutes at 400 degrees.
