Weetbix Slice is one of those slices that’s great to pop into lunch boxes or enjoy as a sneaky snack.
It’s also one that’ll quickly become a family favourite – if it’s not already.
Aussie kids, are Weetbix kids, Aussie kids… are Weet. Bix. Kids!
Remember the jingle?
Weet-Bix was developed in Sydney, Australia during the mid 1920s and first produced in a factory on Parramatta Road, Leichhardt.
But it wasn’t until about 1985 that the jingle came along. And kids had been enjoying their weet-bix for many decades before we sang about it.
Nearly 100 years on, Weet-Bix was voted “Most Trusted Breakfast Food” in the 2022 Reader’s Digest Most Trusted Brands consumer poll.
And while it’s hard to beat starting the day with Weet-Bix, warm milk and sliced banana, we’ve come up with some tempting weetbix recipes in those the past 100 years.
Perhaps none more popular than this Chocolate Weetbix Slice recipe! Yep, weetbix is more than a breakfast cereal (though do check out my Rum Balls made with weetbix recipe at Christmas time and the sweet Weetbix Marshmallow Slice).
I don’t remember a time when my mum didn’t make this slice.
When I think of it, I can see it perched inside a Tupperware container from the 70s. But it didn’t stay there for long. It always disappeared quickly.
I’ve always loved it and here’s some evidence of that: on the original recipe written out by my mum, my much younger self has added a little note.
“Mum I want to cook this.”
And, 30+ years later I’m still wanting to cook this!
Traditional Weetbix Slice: the ultimate “crib” food
My mum has another memory of this slice.
She remembers it as the first slice my Nan Mac (Nana Ling’s daughter) made. She remembers Nan making it regularly for my Pop Mac’s “crib”.
“Crib” is Australian slang for a light meal or lunch eaten at work.
And this lovely memory of my Pop Mac going off to work, in the mines or on a farm, with some of this slice in his crib is just what I love about this slice.
It’s always been the comforting little treat that’s the perfect reward after a hard day’s work. It’s a slice that your family will love – and keep on making – for generations.
Ingredients for Weetbix Slice
To make this slice you’ll need:
- 3 weetbix
- brown sugar
- SR flour
- desiccated coconut
- icing sugar.
Making Weetbix Slice
Start by pre-heating the oven to moderate. Then grease a slice tin (approx 26 x 16 cm) and line with baking paper, leaving excess on the sides to lift out slice once cooked.
Crush the weetbix into a bowl. Really get into it so the weetbix reaches a fine consistency!
Add the remaining dry ingredients to bowl and stir to combine.
Melt the butter and add to dry ingredients. Mix well.
Press mixture into slice tin with hands and even the top surface using the back of a spoon.
Bake in the oven for 20 minutes.
Start preparing the icing a few minutes before the slice is ready to be removed from the oven. This slice is iced while hot from the oven.
Sift the icing sugar and cocoa into a bowl.
Add 2 tablespoons of the boiling water to the butter and allow the butter to melt.
Add the melted butter mixture to the icing sugar and cocoa and mix well.
Add enough of the remaining tablespoon of boiling water to ensure the icing is soft enough to spread. Spread the icing over the slice while still hot.
Sprinkle with additional coconut if desired.
Allow to cool completely before lifting from the tin using the baking paper and slicing into 24 pieces with a sharp knife.

You can also make this slice in an air fryer.
