In a large bowl (I used a stand mixer), whip 1 cup cold cream with 1/4 cup sugar until stiff peaks form. Set aside.
In another bowl, whip cream cheese and remaining 3/4 cup sugar until smooth. Scrape down sides and whip again. Slowly stream in 1 cup cream, vanilla and salt. Scrape down sides and whip again.
Fold whipped cream into cream cheese mixture until uniform in consistency.
Spoon into wax paper-lined air-tight container. Smooth the top and cover with lid. Freeze until mostly solid, about 3 hours.
Top with desired toppings- I used graham crackers and chocolate chips, but chocolate or caramel syrup and nuts would be great, too!
