    Ingredients
    - 150g butter digestive or plain sweet biscuits, crushed
  - 75g butter, melted, cooled
  - 250g cream cheese, at room temperature
  - ½ cup sweetened condensed milk
  - 3 tsp cornflour
  
     - ½ cup sour cream
  - 2 eggs, lightly beaten
  - 1 tsp vanilla bean extract
  - Fresh berries, icing sugar and double thick cream, to serve
  
     Directions
    - 1. Grease and line the base of a 20cm deep-sided loose bottom round cake pan (see Cook’s note) with baking paper. Combine the crushed biscuits and butter. Press firmly into the base and a little way up the sides of prepared pan.
  - 2. Beat the cream cheese, condensed milk and cornflour until smooth. Add the sour cream, eggs and vanilla. Beat until combined. Pour into the crumb crust.
  - 3. Place the rack provided into the inner pot and add 1 cup of water to the cooker. Take two long strips of foil and fold each in half lengthways and then fold in half again. Lay them in a cross on a work surface. Place the cake pan on top and bring the foil strips up the sides of the pan to make a foil sling.
  - 4. Lift the cake pan into the pot. The foil sling makes the cheesecake easier to remove from the pot after cooking.
  - 5. Close lid, select MANUAL program in PRESSURE COOKING, set time for 20 minutes. Press START.
  - 6. When cooking is complete, allow the pot to stand for 10 minutes or until the floating valve has dropped. Turn pressure regulator to VENT. Remove lid.
  - 7. Using heat-proof mitts, remove the cheesecake and place on the bench, discard the foil strips. Cool for 30 minutes, then chill for 4 hours or overnight.
  - 8. To serve, carefully remove the cheesecake from the cake pan. Top with berries and dust with icing sugar. Serve with double thick cream. Cover and refrigerate any remaining portions and use within 3 days.
