In a medium bowl whisk together pudding mix, protein powder, cocoa powder, and optional sweetener.

Add milk to bowl and vigorously whisk for 2 minutes until mixture just begins to thicken.

Add softened cream cheese and continue to whisk until thoroughly combined with no lumps. This takes some patience and effort but will come together in a couple minutes.

Add half the cool whip to the mixture and fold in gently until almost combined. Add remaining cool whip and continue to fold gently until no white streaks remain.

Refrigerate at least 2 hours but overnight is best if you can hold out that long. Eat it right off the spoon or slather on a graham cracker and enjoy!
