Preheat oven to 475°F. Spray a 9” pie plate with cooking spray.
In a large nonstick skillet, melt 1 tablespoon margarine over medium heat. Add apples; cook 5 minutes or until crisp-tender, stirring frequently.
Spoon apples into prepared pie plate; top with shredded cheddar.
In a bowl, whisk cream cheese until smooth, then whisk in milk. Add flour, egg substitute and 1 tablespoon Splenda Sweetener, and salt; mix well. Pour batter over apples.
In a small bowl, stir together remaining Splenda Sweetener and cinnamon; sprinkle this mixture over the batter. Dot with remaining 1 tablespoon of margarine.
Bake 12–15 minutes, or until pancake is puffed and golden brown.
