Preheat oven to 350°F. Place parchment paper on bottom of a 8x8” pan, leaving an overhang.
Combine cookie crumbs and melted butter. Press evenly into bottom of pan.
Process cottage cheese, cream cheese and sour cream in food processor or blender until completely smooth. Add powdered sugar and process until combined.
Add eggs, one at a time, processing just until combined. Pour over crust. Bake 30 minutes or until slightly puffed on edges and set, but jiggly, in center.
Cool on a wire rack until room temperature (about 30 minutes). Refrigerate 3 hours or overnight until chilled. Remove cheesecake from pan and slice into bars. Top with caramel, pecans, mini chocolate chips and flaky salt.
