Equipment

  • Food processor or Thermomix

Ingredients

  • 80 g butter melted
  • 250 g (3/4 cup) condensed milk
  • 250 g plain sweet biscuits like Arnott's Marie biscuits
  • 90 g (1 cup) desiccated coconut
  • Juice from 3 limes
  • Grated zest from 3 limes

For the lime frosting:

  • 360 g icing sugar
  • 90 g butter softened to room temperature
  • 5 tbs lime juice
  • 3 tbs desiccated coconut

Instructions

Conventional Method

  • Grease and line a 22cm X 32cm rectangular slice tin with baking paper.
  • Crush biscuits and place into a bowl. Add coconut and grated lime rind. Mix to combine.
  • Add melted butter, condensed milk and lime juice to the biscuit mixture. Mix thoroughly until well combined.
  • Press into the prepared tin. Place into the fridge.
  • In a bowl, whisk the icing sugar, room temperature butter and lime juice in a bowl until creamy and 'frosting-like' - if the frosting is too thick to spread, add a little more lemon juice.
  • Spread the frosting over the slice, sprinkle with the extra coconut and place back into the fridge to set completely.
  • Cut into slices. Store in an airtight container in the fridge for up to 1 week.

Thermomix Method

  • Grease and line a 22cm X 32cm rectangular slice tin with baking paper.
  • Cut the lime rind off with a sharp knife. Place the lime rind into the TM bowl and chop finely on Speed 8 for 50 seconds or until it has a finely grated feel (you will need to scrape down the sides of the bowl a few times).
  • Add the biscuits and crush on Speed 7 for 5-10 seconds or until the biscuits resemble fine crumbs. Set the biscuits and lemon rind aside.
  • Place the butter into the TM bowl and melt on Speed 3, 60 degrees, 2 minutes (you may need to scrape the sides of the bowl down with a spatula after 1 minute).
  • Add the condensed milk and lime juice. Mix on Speed 3 for 5 seconds until well combined.
  • Add the dry biscuit mixture and the coconut to the TM bowl. Mix all ingredients together on Speed 4 for 5 seconds. Scrape down the sides with a spatula and mix again on Speed 4 for an extra 10 seconds.
  • Firmly press the mixture into the prepared tin and place into the fridge.
  • Place the icing sugar, butter and lime juice into the TM bowl and mix on Speed 4 for 20 seconds. Scrape down the sides of the bowl with a spatula. Mix on Speed 4 for an extra 30 seconds.
  • Spread the frosting over the slice, sprinkle with the extra coconut and place back into the fridge to set completely. 
  • Cut into slices.Store in an airtight container in the fridge for up to 1 week.
