For a healthier option, you can substitute the all-purpose flour with a gluten-free blend or use Greek yogurt in place of butter. For a fruity twist, consider adding crushed raspberries or strawberries on top of the cheesecake layer or swirl in some caramel sauce for extra decadence. Store any leftovers in an airtight container in the refrigerator for up to 3 days. Best served chilled.
