Equipment

  • Thermomix

Ingredients

For the base

  • 50 g butter chopped
  • 250 g plain sweet biscuits like Arnott's Marie
  • 395 g sweetened condensed milk
  • 15 g lemon juice
  • 45 g desiccated coconut

For the icing

  • 300 g pure icing sugar
  • 30 g of lemon juice
  • 25 g extra desiccated coconut to decorate, optional

Instructions

  • Line a 28cm x 18cm slice tin with baking paper, making sure to leave paper hanging over the sides.
  • Place the butter into the Thermomix bowl and melt on 2 minutes, 60 degrees, Speed 3 or until melted.
  • Add the biscuits and crush for 10 seconds on Speed 8.
  • Add the sweetened condensed milk, lemon juice and coconut (plus finely grated lemon zest if using) to the bowl and mix on Speed 4 for 15 seconds or until combined. Use your spatula to help scrape the sides of your bowl mid way through mixing.
  • Pour the mixture into your prepared slice tin and use the back of metal spoon to spread it across the tin.
  • To make the icing, place the icing sugar into the Thermomix bowl and sift by pressing Turbo for 5-10 seconds. Add the lemon juice and mix for 30 seconds on Speed 4.
  • Note: If your icing is too thick, add a little extra lemon juice to the mixture until it is a thick but spreadable consistency. If the icing is too runny, add a little more icing sugar and mix again.
  • Pour the icing over the top of your slice and sprinkle the extra coconut over the top.
  • Place the slice into the fridge for 6 hours (preferably overnight) to allow it to set.

Notes

RECIPE NOTES & TIPS
To make your slice extra lemony - add a tablespoon of finely grated lemon zest to the base mixture.
Spreading the slice - The slice base mixture is quite soft and sticky and you will need to use the back of a spoon to help spread it across your tin.
Cutting - Ensure your slice has completely set before cutting it into pieces.
Store and freeze - Store in an airtight container in the fridge for up to 1 week or freeze in an airtight container for up to 3 months.
