Whisk together the cream cheese, Mascarpone cheese and icing sugar until well combined. Add in the double cream and vanilla extract and whisk again. Set to one side.
To make the cheesecake crumbs, stir the melted butter into the digestive crumbs - you should have a sandy mixture.
Heat the pancakes gently, then fill each pancake with a few spoonfuls of the cheesecake mixture. Sprinkle over some blueberries or other fresh fruit and then the sandy cheesecake biscuit crumbs. Fold each pancake over, dust with icing sugar and drizzle over some maple syrup or fruity sauce.
