Turn heat to low and simmer for 5 minutes. Pour in the cornstarch water mixture to thicken. Turn off heat and chill.
Chill All Purpose Cream overnight and whip using a handmixer.
Combine with condensed milk.
Put 2 tbsp of the mixture on the glass dish or microwaveable container.
Arrange Graham Crackers in the container. Then top with the cream mixture.
Top with the Strawberry topping.
Repeat procedure to form 2-4 layers.
Keep in the refrigerator for 4 hours or until the graham is moist with cream.
