Chilling both the base and the pan helps the shortbread hold its shape and stay tender, while a brief chill after baking ensures clean slices and a creamy set cheesecake layer. For crisper edges bake closer to 22 minutes, and for a softer, creamier center pull at 18–19 minutes when there’s a slight jiggle. Swap raspberry jam for lemon curd, blueberry preserves, or a thin layer of salted caramel, and add a pinch of cinnamon or almond extract to the dough for variation. Ensure cream cheese and butter are truly soft to avoid lumps, and avoid overmixing the flour in the shortbread to keep it crumbly. Store covered in the refrigerator up to 5 days, or freeze cut bars well wrapped for up to 2 months; thaw in the fridge before serving.
