Instructions

Conventional Method

  • To ensure a smooth cheesecake, bring all ingredients to room temperature before starting.
  • Grease and line the base and sides of a 23cm spring-form pan with baking paper and set aside.
  • Finely crush 300g of the Tim Tam biscuits in a food processor and place into a bowl. Note: Reserve the extra 100g for the cheesecake layers.
  • Add the melted butter and mix until well combined.
  • Press the mixture firmly into the base of the pan and place into the fridge while you prepare the cheesecake layers.
  • Roughly chop the remaining 100g of Tim Tams. Set aside.
  • Using hand-held beaters or a stand-mixer, whip the cream until soft peaks form. Set aside.
  • Pour ¼ cup of hot water into a cup, sprinkle over the gelatine powder and stir with a fork until dissolved. Set aside and allow to cool.
  • Beat the cream cheese, vanilla bean paste and caster sugar until smooth and creamy.
  • Add the cooled, dissolved gelatine to the mixture and beat until well combined.
  • Divide the mixture equally between two bowls.
  • Melt the milk chocolate in the microwave on 50% power for 3 minutes (or until melted). Allow to cool slightly.
  • Fold the melted milk chocolate, half of the whipped cream and half of the chopped Tim Tams through one portion of the cream cheese mixture.
  • Spoon the milk chocolate cheesecake mixture into the prepared tin. Spread out evenly with a spoon.
  • Place into the fridge for 15 minutes.
  • Melt the white chocolate in the microwave on 50% power for 3 minutes (or until melted). Allow to cool slightly.
  • Fold the melted white chocolate, the remaining whipped cream and chopped Tim Tams through the second portion of the cream cheese mixture.

  • Place the cheesecake into the fridge to set for a minimum of 6 hours.
    TIP: For best results, leave in the fridge overnight.

Notes

RECIPE NOTES & TIPS
Ingredients Info:
  • Tim Tams - an iconic Australian chocolate coated biscuit. These can be substituted for any brand of chocolate coated biscuit (like Penguins) or alternatively, Oreos.
  • Cream cheese - for a smooth cheesecake, ensure the cream cheese is at room temperature before mixing. Use blocks of full fat cream cheese (not light or spreadable). I like to use the Philadelphia brand.
  • Gelatine powder - dissolved in hot water. This helps the cheesecake to set and hold its texture when served. You can read about why I always use gelatine in my no-bake cheesecakes here (this is especially important if you're making a cheesecake for an event or party).
More Recipe Tips:
  • Chilling time - this no-bake cheesecake requires a minimum of 6 hours chilling time. If time allows, it's best to chill the cheesecake overnight before serving.
  • Serving - remove the Tim Tam cheesecake from the fridge and decorate with extra chopped Tim Tams. As this cheesecake contains gelatine, it can be left out of the fridge for a couple of hours without losing it's texture.
  • Storing & freezing - store the cheesecake in the fridge and consume within 3 days. Alternatively, you can freeze the cheesecake as a whole or in individual portions. Wrap in a layer of plastic wrap and then a layer of foil and freeze for up to 1 month.
