Ensure cream cheese and eggs are at room temperature for a smoother texture. Don't overmix the filling once eggs are added. Allow gradual cooling in the oven and full chilling in the fridge to prevent cracks. Slice bananas for topping just before serving to prevent browning. Store leftovers in an airtight container in the refrigerator for up to 3-4 days; add fresh toppings to individual slices. You can use a different crust like graham cracker or add caramel, chocolate chips, or spices like nutmeg/cinnamon. A tablespoon of bourbon can be added to the mashed bananas or pudding for a grown-up version.
