Notes
Variation: Swap shortbread with vanilla wafer crumbs, or use chocolate cookies for a black forest vibe. For cleaner slices, freeze 20 minutes before cutting. Optional: Bake the crust at 350°F for 8 minutes, then cool completely for an extra-firm base.This recipe is an original creation inspired by classic Cherry Cheesecake Cookie Crust flavors.
