Childhood fave: Weet-Bix slice with chocolate icing

Fat Mum Slim /

Weetbix Slice

Back in the day, when I was in primary school, we used to have a ‘thing’ called Cake & Slice day. Parents would bake their hearts out late at night, and the kids would take the goods into school the next day to be sold. We had a huge table in the playground where all the cakes and slices would be set up, and the kids would come along with their silver coin and purchase a little baked goodie.

My Ma always made one of two slices, either chocolate fudge bars {so good!} or Weet-Bix slice. Instead of trying another family’s creation, I always looked out for my mum’s slice and paid 20c for a piece. I was kinda funny like that.

I hadn’t tried Weetbix slice since back in those days at school, and I actually thought that I probably wouldn’t like it. Weet-Bix? In a slice? Maybe it wasn’t as good as I remembered. When I mentioned to Hubby, who is totally NOT a Weet-Bix kid, he turned up his nose.

I’m a Weet-Bix kid from way back. It was my breakfast of choice, and still is. Lacey had her first try on the weekend, and she’s not a fan either. “Too slobbery,” she said.

Thankfully they both liked the slice. The Weet-Bix adds a little crunch to the base. I’d pay 20c at least for it. Do they still have Cake & Slice days at schools?

Weetbix Slice


3 Weet-Bix, crushed
1 1/2 cups self-raising flour
1 cup dessicated coconut
150g butter, melted
3/4 cup brown sugar

3/4 cup icing sugar
2 tbs cocoa
50g butter, melted
1 tbs hot water


♥ Preheat oven to 180 degrees Celsius.
♥ Grease and line a tray with baking paper.
♥ Place all the dry ingredients into a large bowl. Mix to combine. Add melted butter and stir until completely combined.
♥ Press the slice into the tray, smooth over with the back of a spoon and bake for 20-25 minutes, or until golden brown.
♥ While the slice cools, make the icing. Mix all ingredients in a small bowl, until smooth and combined. Pour over slice and spread until completely covered. You can sprinkle with a little coconut for added fancy.

Note: I’m not sure if Weet-Bix is sold anywhere other than Australia, but it’s a breakfast cereal. You can see a picture here, and maybe find an alternative where you live.

What treat was your favourite as a kid?

    Thank you for sharing this recipe. I will be making these today. I have weet bix sitting in the pantry waiting to be used in other creative ways than breakfast. Have a fabulous day.

    • I bought the bulk pack for $1 the other week on special… so I need to get creative in ways to use it! Enjoy the slice. x

  • Weetabix here in the UK and, I believe, just about everywhere else.

    • Captain Obvious

      Your point??? I’m sure anyone with half a brain could have figured that out…

  • mum used to make this too – ‘cept the iciing was a little thinner and she always added sprinkles. Hmmm, might have to hit her up to make some ; )

    There is nothing like the goodies your Mumma bakes. My kids love my Mum’s Jam Drop biscuits and Cherry Ripe slice. I’ll have to give the weetbix slice a go, I’m sure they’ll love it.

  • Holly R

    Thanks for this. My mum mentioned this the other day when my son tried weetbix and I thought she was making it up- I’ve never tried it, or even heard of it!! oops- sorry mum! Might even give it a go, looks pretty delicious!

  • YUM!!!!! Off to make this today for the kids (and perhaps I may have a slice with a coffee!. We live in SIngapore and you can get weetbix here! Thanks for sharing x

  • You made it interesting and yummy from boring breakfast. I might try with whole wheat flour. Thanks for recipe 🙂

  • Weetabix in Canada and I it was my favorite childhood cereal! I can’t wait to try this recipe!

    I love weetbix slice, my kids love weetbix slice, every one I know loves weetbix slice. When daughter #1 was a baby I joined a new mothers group to meet some people as I had moved from QLD to Melbourne and I was a bit lonely. The first time we had a morning tea, I took my weetbix slice – I am so glad I did because the other choices were goats cheese and olive slice, salmon and yuck pate, eggplant and muck on dry bread and a few crudities. I was the only one to bring something simple and sweet. All of my slice got eaten with plenty of the ‘good’ food left.

    Sounds delicious but as I have a coeliac no good for us. I have just made a beautiful raw chocolate slice though which looks very similar so that will have to do 🙂

  • Kelpad

    I manage a school canteen and quite often make this slice…..sometimes with lemon icing! But, reading your post, I’m going to start a slice day on Fridays!

  • We have what they call a bake sale, we actually have one next week to raise money for Syrian refugees. I’m going to make this!

  • Paula

    Just made this last week for my daughters bake sale at school in NZ. Her Grandma is from Sydney and we have always called this “Sydney Special”

  • Racheal Clark

    whipped this up and blogged it today, feeling super organised for a change! lol

  • Sue Gabbay

    We can now buy Weetabix here and I will try this. When I was small I could not eat eggs so when my mother made a cake, I was given saltine crackers with icing. I still like the sweet/salt taste combination.

  • Tiia

    I need to try this recipe, as well as your older post’s chocolate fudge
    bars, they both sound delicious! I’ve wanted to learn to make more sweet
    things with coconut, and you’ve just provided me with two great ideas! I
    used to love the mocha cake bites, that had the most delicious
    chocolaty coffee icing and the most colorful sprinkles 🙂

  • I always save my weetbix crumbs as my son won’t eat them and use them to make a slice very similar to this, but it has a caramel filling in the middle!!! This one’s even easier though!!

  • Rina Gous

    We have Wheat-bix in South Africa – will be making these this weekend. Thanks for sharing

  • Sarah

    We just returned from our (amazing, wonderful and beautiful) trip and had our fair share of Weet Bix for breakfast and in a granola/mulsei bar type recipe. I sorta fell in love with them and wish I would have brought some home!

  • Mel

    Awesome thanks mmmmmmm yummy

  • Sue

    How about the recipe with the caramel filling that sounds nice
