If baking the crust*, preheat oven to 350°F (175°C). Combine the cookie crumbs and butter until thoroughly combined. Press into the bottom and up the sides of a lightly greased 9-inch pie or tart pan.
Place the pan in the refrigerator while you make the filling, or bake on a lined, rimmed baking sheet for 10 minutes then allow to cool completely.
To make the filling:
Using an electric mixer on medium speed, beat the cream cheese, sugar, and vanilla until thoroughly combined and smooth.
Placed the cream in a separate bowl. Using an electric mixer with a whisk attachment, whip the cream on high speed until soft peaks form.
Fold about 1/3 of the whipped cream into the cream cheese mixture. Then gently fold in the remaining whipped cream, mixing just until combined.
Transfer the filling to the prepared crust, and spread evenly.
Stir the preserves well to thin them a bit. (If your preserves have large pieces of fruit, remove those for best results.) Drop small portions of the preserves over the filling. Use a toothpick or thin knife to swirl into the filling. Refrigerate at least 4 hours before serving.
Notes
*Baking the crust it optional. I find that baking it makes it a bit sturdier and also enhances the flavor.
