This is so good I like it better than traditional pumpkin pie
Instant vanilla pudding mix contains modified food starch and sodium phosphates that act as immediate moisture absorbers. Without this dry powder, canned pumpkin releases too much liquid into the crust. Whisk the pudding powder directly into the thawed whipped topping before introducing the squash puree to prevent lumps from forming in the fat emulsion.
Commercial whipped topping contains emulsified vegetable oils and hydrogenated palm kernel oil, which resist weeping better than dairy cream. Fold the pumpkin base into the whipped mixture gently with a silicone spatula. Vigorous stirring deflates the trapped air bubbles that give this dessert its airy consistency.
This dessert relies entirely on refrigeration rather than baking to set its structure. Keep the pie chilled at or below 40 degrees Fahrenheit for at least four hours before slicing. Freezing is not recommended because the thawed whipped topping separates and ruins the mouthfeel.
