For a gluten-free option, you can use gluten-free graham crackers or almond flour for the crust. Optional variations include topping your cheesecake with fresh berries, chocolate ganache, or a drizzle of caramel sauce. Store leftovers in an airtight container in the refrigerator for up to 5 days. Cheesecake can also be frozen; just wrap it well in plastic wrap and foil for up to 3 months, then thaw it in the fridge before serving.
