In a medium bowl, whisk together the instant pudding mix and 1 cup of milk. Whisk until the mixture is smooth and begins to thicken, about 2 minutes. Let it sit for a couple of minutes to firm up slightly.
2. Fold in the Cool Whip:
Gently fold the Cool Whip into the pudding mixture. Use a spatula to mix until smooth and creamy, ensuring there are no lumps.
3. Add flavor (optional):
If desired, you can add 1 teaspoon of vanilla extract to enhance the flavor of the frosting.
4. Chill and frost:
For best results, let the frosting chill in the refrigerator for 15-20 minutes before using to allow it to firm up a bit more.
Once chilled, spread it onto cakes, cupcakes, or any other desserts you’d like to frost.
