*To make muffins, spray two muffin pans with cooking spray. Sprinkle the greased muffin cups with the cinnamon sugar mixture. Fill the muffin cups 2/3 full with batter. Bake at 425 for 5 minutes, then without opening the oven, reduce the oven temperature to 375 degrees and bake for an additional 13 minutes or until the top of the muffin bounces back when you touch it.
