- Preheat Traeger to 350℉. In a small bowl, combine cookie crumbs, sugar and melted butter. Press into a springform pan and refrigerate while you make the filling.
- Make the filling by beating cream cheese and sugar until well-blended, and then stirring in eggs, pumpkin, salt and cinnamon. Beat until smooth.
- Pour filling into chilled crust and place in the center of your preheated grill. Bake for 50 minutes until filling is set and no longer jiggles. While it bakes, combine the sour cream, brown sugar and vanilla and blend well.
- Carefully remove pan from Traeger and pour sour cream topping over cooked filling. Smooth with a spoon and return to the grill for 5 more minutes. Remove from grill, cool slightly and refrigerate at least 2 hours before serving.
