To freeze: Spray 2 (8-inch) disposable foil cake pans with cooking spray. After covering pans with sprayed foil, place in gallon-size resealable freezer plastic bags, or wrap in double layer of plastic wrap. Label and freeze. To bake: Thaw overnight in refrigerator. Heat oven to 350°F. Remove from plastic, and place foil-covered pan(s) on cookie sheet. Bake 35 to 40 minutes or until instant-read thermometer inserted in centre reads 165°F. If baking from frozen, bake 1 hour, then remove foil and bake 10 to 15 minutes.
