Just imagine a block of Caramilk chocolate and everyone's favourite Custard Slice had a love child. The resulting dessert would be this amazing Caramilk Custard Slice.

Cadbury Caramilk chocolate has a bit of a cult following amongst chocoholics at the moment. A fellow Thermomix enthusiast came across this recipe on "Australia's Best Recipes" website. She sent out a message for a Thermomix conversion to be written. I couldn't resist giving it a go.

I promise this is a "drop dead, simple" recipe to make. The custard slice is "no-bake" and sandwiched between two Arnott's Lattice Slice biscuits. It would be a fabulous recipe to make with the kids.

Substitute Ingredients

In some areas, Arnotts Lattice biscuits are no longer available. If you have trouble finding this product simply swap them for SAO biscuits. It won't make any difference to the recipe results.

Original Caramilk Custard Slice Recipe

The original recipe used just one block of Cadbury Caramilk Chocolate. Half was used in the filling and half in the ganache.

When I went to make the original ganache topping I found that it didn't set. Those followers who were watching me on Facebook live would have seen me waiting for the ganache to thicken enough for me to pour over the slice. Basically, it never achieved a useful consistency. The recipe had too much cream.

So this meant I needed to discard the mixture... in my belly and start again. I decided to use my regular ganache recipe and substituted Caramilk Chocolate. Just to make sure there was enough topping to cover the slice I increased the volume of the ganache slightly. The adjustment ensured coverage of the chocolatey goodness over all the squares.

Hi, what size square tin would be best? Thanks

- Julie Carlyle says
  
  July 26, 2020 at 10:36 am
  
  Hi Row
  You can use any tin larger than an 18cm Square (7inch)
  I didn’t have a square tin so I used a large rectangular roasting tray and just lined it with plastic wrap.
  Happy Cooking
