Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.
- Plain Sweet Biscuits - known as cookies in the US. You can use any type of plain sweet biscuits you like. I generally use Arnotts Marie biscuits, which are popular here in Australia.
- Rice Bubbles - also known as Rice Krispies. You can use any brand of puffed rice you like. Ensure you use a brand new (unopened) packet of Rice Bubbles to avoid stale tasting slice!
- Butter - you can use either salted or unsalted butter in this recipe.
- Sweetened Condensed Milk - use full fat (not skim or light) sweetened condensed milk.
- Cocoa Powder - unsweetened cocoa powder.
- Maltesers - also known as Whoppers in the US. Cut in half before using in this recipe.
- White Chocolate - use white chocolate melts or baking chocolate (not chocolate chips as they don't melt as well).
- Coconut Oil (optional) - this helps to stop the chocolate from cracking when it's cut into slices.

Val says
Do you need to wash the bowl before doing the white chocolate step?
Lucy says
Hi Val, yes you do 🙂
Cara says
Hi, is cutting each Malteser necessary? Could you chop them for a few seconds in the bowl beforehand to save time? Thanks
Lucy says
Absolutely! Just press Turbo for 1 second and check them!
Erin says
Wow. Absolutely delicious!! Will definitely make again and again! Xx
Andrew says
Does this work with a milk substitute rather than condensed milk?
Lucy Mathieson says
Hi Andrew, the condensed milk is needed to 'stick' the whole slice together. 🙂
Alicia says
The rice bubbles went all stayle. It would be so good if they didn't do this 🙁 are they meant to do that? Not stay crunchy?
Lucy Mathieson says
Hi Alicia, unfortunately due to the nature of rice bubbles, they wont stay crunchy for long (a bit like when you add milk to them in your cereal). Keeping the slice in the fridge might help a bit though!
Cherie says
Hi just made this slice and it is very Yummy. The kids are going to love it when they get home from school. I am just a novice and wondering if you can freeze this slice as it made a massive amount and although very yummy too much to consume within a couple of days.
Lucy says
Hi Cherie,
You can freeze this slice (in an airtight container). xx
Karen says
It doesn't say when to put the coconut oil in????? Hope it turns out ok.
Lucy says
Hi Kaz, sorry it's with the chocolate when melting. I'll add it in now!
Thanks!! PS - it won't matter if you don't use it (it just makes it easier to slice - thats all!!).
