I did freeze the crust and it was a bit hard, so I recommend refrigerating the crust instead of freezing.
I used 1 cup sugar and it was a bit too sweet for my taste. If you dont like your desserts too sweet, i suggest you add 3/4 cup sugar, do a taste test & add more, if required.
I used Kiri cheese for this, but you can use Philadelphia cream cheese also. If you are in india, you can use Amul Cheese spread for the same.
Keep it at room temp for 10-15 mins, before serving.
I got 11 mini cheesecakes and 4 individual cheesecakes (medium size portion)
