Mix together pudding, jello, and water in saucepan over medium heat until it boils.
Once it comes to a full rolling boil, remove from heat and pour into large bowl.
Cover with plastic wrap and refrigerate until mixture has thickened (about 4 hours or overnight).
With an electric mixer, beat jello until creamy. Gently fold in Cool Whip.
Then add in raspberries until completely mixed together.
Stick back into the fridge and chill for about an hour before serving.
Notes
We do not recommend making this recipe in advanced. We find the juice from the raspberries can make the salad runny, especially if you use frozen raspberries.
We have not made this salad using sugar-free jello or pudding, but in everything that I have read about sugar-free jello, it should still work out great for this recipe!
We do not recommend substituting Cool Whip for this recipe. If you use fresh whipped cream, you will not get the same fluffy consistency.
