Weetbix Slice

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.

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: a note from my much younger self to my mum, written on her recipe for Weetbix Slice.

“Mum I want to cook this.”

And, 30+ years later I’m still wanting to cook this!

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 Weetbix 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. 

Weetbix Slice in the Air Fryer

You can also make this slice in an air fryer.

So whether you’re away in the caravan or your oven is busy with other things, you can still bake up a batch of this crowd-pleaser.

Included below are additional instructions for making this slice in the 3.2L Kmart Air Fryer.

Prep Time: 15 minutes
Cook Time: 20 minutes
Total Time: 35 minutes
Servings: 24 pieces
Calories: 120kcal

Ingredients

  • 3 weetbix (or 55 grams of another similar wheat-based cereal)
  • 1/2 cup brown sugar
  • 1 cup SR flour
  • 1 cup desiccated coconut
  • 1 teaspoon cocoa
  • 125 grams butter

Icing

  • 1 1/2 cups icing sugar
  • 1 tablespoon cocoa
  • 1 tablespoon butter (15 grams)
  • 1-2 tablespoon boiling water

Instructions

  • Pre-heat oven to moderate (I use 170 degrees celsius, fan-forced).
  • 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 weetbix into a bowl.
  • Add remaining dry ingredients to bowl and stir to combine.
  • Melt 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.
  • Cook 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.

Icing

  • Sift icing sugar and cocoa into a bowl.
  • Add 1 tablespoon of the boiling water to the butter and allow butter to melt.
  • Add melted butter mixture to icing sugar and mix well.
  • Add a little extra boiling water if necessary so the icing is soft enough to spread. Spread the icing over the slice while still hot.
  • Allow to cool completely before lifting from the tin using the baking paper and slicing into 24 pieces.

Airfryer Method

  • Using the 3.2L Kmart Air Fryer (or equivalent), use a circle of baking paper to line the basket so the paper reaches about one third to half way up the side of the basket.

  • Make the slice base according to the instructions above and pour mixture into air fryer basket.

Hi Tracey. Thanks for the review and comment. Did you use a 26 x 16 cm slice tin? The quantities should work well for this size tin. Libby :)

It looks yum, and I'm fasting so ....

I love the story behind it even more Libby, down to your cute hand-written note to your mum, and the Pop Mac crib story. I love hand-written recipe books- they're full of history in all the splodges and stains and hand-writing :)

Hi Zohra! Aww, thanks for your lovely comments. And you've reminded me of one of my favourite Sydney memories - the Lebanese sweets shops bustling each night during Ramadan and the wonderful special Ramadan desserts. Ramadan Mubarak.

I remember eating this but my Mother never made it nor have I. It must have been at a friends house. Just reading the ingredients I can taste it and relive the memory. Must try this.
