Place the digestive biscuits in a small ziploc bag and crush them with a rolling pin until they reach your desired consistency. (If you have a food processor, place them in a food processor for about a minute or two). Place the crushed digestive biscuits into a mixing bowl, pour in the sugar and mix well. Then add the butter and mix well. Place the digestive base into a dessert glass or a food ring mould. Set aside.
Add all cheesecake ingredients into a mixing bowl. Whisk until well combined. Pour the raspberry sauce into the bowl and whisk until well combined. Pour into your cheesecake jars or food ring mould over the digestive base.
