Add boiling water to gelatin mix in a large bowl and stir until gelatin has dissolved. Add berries and stir until gelatin starts to thicken slightly. Stir 1/2 cup gelatin mixture into Cool Whip with a whisk until well blended. Scoop desired amount of vanilla ice cream in individual serving dishes or large bowl. ( THIS STEP IS OPTIONAL) Spoon gelatin/Cool Whip mixture into serving dishes. Cover with remaining raspberry gelatin mixture. Pop in Freeze for 10-15 minutes so everything gets thick but not completely frozen. ENJOY!
