Peach Cheesecake with Digestive Biscuit Streusel

How much a slice of cheesecake cost in Singapore nowadays? $6-$8. Quite steep to me, which gives me a good excuse to watch the calories. However, as a fan of cheesecakes, I can't help baking at home occassionally. I have tried different flavor of cheesecakes at home, e.g blueberry cheesecake , chocolate cheesecake , Oreo cheesecake and peach cream cheese cobbler . By far the most popular one is still peach cheesecake with digestive biscuit streusel.
