Heat oven to 350°F. Spray 9-inch glass pie plate with cooking spray. Make Crust. In 1-gallon resealable food-storage plastic bag, place cereal. Finely crush with rolling pin. In small bowl, stir crushed cereal and melted butter until well mixed. Press Crust firmly and evenly in bottom and 1 inch up side of pie plate. Bake 9 minutes; cool 20 minutes.
Meanwhile, in medium bowl, stir Topping ingredients until well mixed; let stand while making Cheesecake so strawberries will become juicy. In separate medium bowl, beat all Cheesecake ingredients with electric mixer on medium speed until smooth; spoon over crust. Refrigerate at least 30 minutes.
To serve, spoon Topping over Cheesecake slices. Cover and refrigerate any leftovers.
