In a small bowl, whisk together strawberry gelatin and water until the gelatin is mostly dissolved. (You will still see some granules.) Set aside
To the bowl of a stand mixer fitted with the paddle attachment, add cream cheese. Mix on medium speed until smooth.
Stop the mixer. Add confectioners' sugar, strawberry gelatin, sour cream, and vanilla. Mix on low until smooth, stopping to scrape the sides of the bowl as needed. Set aside.
In a separate large bowl, pour in the heavy whipping cream.
Using a handheld mixer, start mixing at the lowest speed, gradually increasing to medium and then high speed until the cream thickens and stiff peaks form. Stiff peaks refer to the whipped cream peaks that stand straight up and hold their shape. This will take about 3-5 minutes.
Fold the whipped cream into the cream cheese mixture until fully combined. Transfer to serving dishes and serve immediately or store in the refrigerator until serving.
