apple pie filling—just keep the amounts the same.
If you want a little more texture, you can press a simple base into the bottom of each glass dish before adding the cheesecake mixture: crush about 3 cups of graham crackers or vanilla wafers, mix with 1/2 cup melted butter, and press it firmly into the bottom of the pans, then proceed with the recipe as written.
For a lighter version, you can use reduced-fat cream cheese and a light cheesecake pie filling; the texture will be a bit softer, but still very tasty. If you have a family member who likes things less sweet, serve their bar with a spoonful of plain Greek yogurt on the side to balance the sweetness.
To make it feel extra special for holidays, add a sprinkle of mini chocolate chips or shaved chocolate on top
