One of the most popular recipes on my website, Chocolate Weetbix Slice is the ultimate, nostalgic, sweet treat. Made with pantry staples, and family-favourite Weetbix, this crunchy chocolate slice is so comforting.
This Chocolate Weetbix Slice is a perfect treat. It's ideal with a nice hot cup of coffee in the afternoon and also a hit with the little ones. This recipe incorporates the humble Weetbix, a breakfast favourite for many Kiwis and Aussies. Sometimes it is called Wheat Biscuits or in the UK Wheetabix.
Ingredient notes:
All of the ingredients needed are pantry staples. It's fairly quick to whip up, so it's the perfect go-to treat!
- Weetbix: One Weetbix biscuit weighs 16g so this recipe is a great one to use up the crumbly bits at the bottom of the box. If you love Weetbix recipes as much as me, be sure to check out my whole collection of The Best Weetbix Recipes.
- Coconut: A lot of people don't like coconut! To make this slice without coconut simply add 1 extra Weetbix and an additional ½ cup of flour.

The Weetbix and coconut give the chocolate slice the perfect texture. It's soft but with a little bit of crunch, this depends on how long you cook it for. If you want a bit more flavour and texture you could add in some chopped nuts.
Pair this with the smooth, rich, velvety chocolate icing and you've got yourself a tasty slice for a sweet snack or an after dinner treat!
Step by step instructions:
Preheat the oven to 180°C fanbake. Place the butter, sugar and cocoa in a large saucepan and melt them together over a low heat until combined.
Remove the pan from the heat and add the crushed Weetbix, flour, coconut and baking powder. Mix everything together well. Pour into a lined tray and press firmly. Bake for 15-20 minutes.
To make the icing, mix together the icing sugar, cocoa and butter. Add boiling water as needed to loosen the mixture and whisk out any lumps.
Ice the slice while still warm. When the slice has cooled and the icing has set, slice into pieces.
Other recipe variations of Weetbix slice:
If you want more recipes for Weetbix slice I have created two versions without cocoa in the base: Lemon Weetbix slice and Passionfruit Weetbix slice. They are both proving to be very popular with my readers giving me great feedback. My Weetbix chocolate chip cookies are super delicious too!
If you don't have any Weetbix on hand you could try this similar recipe using cornflakes from my fellow food blogger friend Anna at Just a mum for Chocolate cornflake slice.
Recipe FAQs:
Yes. If you overcook Chocolate Weetbix Slice it can go quite hard. I recommend baking this for 14-20 minutes however, all ovens are different. If you know your oven 'runs hot' test it at the 15 minute mark. It should be soft when you bring it out of the oven and it will firm up as it cool down.
You can try adding dried apricots or cranberries to the base. Walnuts can be added on top of the icing.
Yes! Gluten free Weetbix are available in most supermarkets in New Zealand and Australia. Replace the same amount of weetbix and flour for gluten free alternatives.
My slice tin is approximately 29 x 19cm. Anything close to this will work. The smaller your tin, the thicker your base will be and the longer it might take to cook.
Yes, Weetbix slice will still work well without coconut, simply add 1 extra Weetbix and ½ a cup of additional flour.
Storage:
Chocolate Weetbix slice will keep well in an airtight container in the pantry, or fridge for up to one week.
Did you know you can freeze slices? A great option if you don't want to eat the whole slice in one go! Simply wrap the slice pieces in cling film and store in an airtight container in the fridge for up to three months.
Top tips:
If you chose to freeze pieces of this slice, they are perfect for adding to school lunches. Simply place a frozen piece of slice in a lunchbox in the morning, and it will have defrosted by morning tea time. In addition, it will help to keep the rest of the lunch cool!

Hi, could one leave the coconut out as I cannot eat it?
VJ cooks
Yes, Weetbix slice will still work well without coconut, simply add 1 extra Weetbix and ½ a cup of additional flour.
Sandra McDonald
Great, none of my family like coconut and I find it gives me a sore stomach
Jane
Delicious made it with 3/4 cup brown sugar…yummy
April
Hi! I only have about 100gms butter could I substitute the rest for margarine/ table spread? So low on ingrediants and can't get to the shops but need baking for lunches. Tha ks in advance 🙂
VJ cooks
Yes that should be fine. I would far rather substitute than go to the shops too!
Sherralynne
We really enjoy this Weetbix Slice. Crunchy and not too sweet, this slice keeps well and we make it often. Thanks Vanya!
VJ cooks
Thanks so much for the feedback 🙂
Jo
Hi, have just made this slice and is a huge hit! Just wondered is it better kept in or out of the fridge?
VJ cooks
Truly, either is fine. It comes down to personal preference.
Ria
Hi there. I don’t have icing sugar - amateur mistake. Will sugar be ok?
VJ cooks
For the icing? No, you definitely need icing sugar for icing sorry!
Monique
Granulated sugar in a food processor or blender - will become icing sugar. If you intend to store, add cornflour.
VJ cooks
Great tip, thanks Monique.
Ellie
Vanya, quick i need your help. I just made this slice but i doubled the recipe and when i put it in the tray it's absokutely soaked in butter. I used 370gm, how do i fix this?
VJ cooks
Are you sure you doubled all the ingredients as well? I know it's easy to miss one when you're doing the calculations in your head for each item...?
Aimee Tait
Does this freeze well?
VJ cooks
Yes, no problems 🙂
Magnus
Hey, love your recipes, do you have a YouTube or way I can see your recipes on youtube? Trying to scroll through this page to find a YouTube link. There are so many ads on this page everywhere. And I'd like to just be able to see the recipe by itself and save it and also share the recipe videos to my mum and friends. But it's not letting me share the video. And after the ads, it's making it abit hard to navigate. Some are covering the content for me.

Hi! Can this slice be frozen?
VJ cooks
Yes it can!
Melinda
Hi Vanya
I made the weetbix slice but the base was very crumbly. How can I solve this please.
VJ cooks
Hi Melinda, the longer you cook it, the harder the base becomes. Every oven is different so you may have to alter the cook time in yours.
Amy
I’m usually a fan of the “no bake” slices with 3 kids under 5 BUT this slice by far beats all of baked so fat. Quick and simple and so delicious.
Amy
All “I’ve” baked so “far”
VJ cooks
Thanks Amy, it's such a goodie!
Monique
I use this recipe often! Its so yummy and easy to make, thank you for making the recipe available. When I made this recently I had run out of icing sugar so instead of going to the shops I melted a block of Whittaker's creamy chocolate that I had in the cupboard and used that as the "icing" layer, a yummy second option I think <3 😉
VJ cooks
Oh wow that sounds delicious, an excellent alternative! Thank you for the feedback, that's so lovely to hear 🙂
Ann
What can you use instead of weetbix?
Jannefer
I am going to make it is it good for a 1 year old , love your recipes
VJ cooks
It's really up to you!
Georgia
Do you reckon this would work aswell with other cereals such as cornflakes, Rice Bubbles, coco pops etc
VJ cooks
I haven't tried any other cereals sorry. The texture of the Weetbix is quite important to the texture of the slice.
Marie Roberts
How many pices does this recipe make please?
VJ cooks
Between 24-30 depending on how big you cut them.
Alison
Delicious and do dinner to make, thank you for the recipe.
jude thompson
what size tray do i use to bake this in?
VJ cooks
Hi Jude, I use a standard slice tin which is 29 x 19cm
Dana
HI VJ,
thank you for this recipe! New to wheetbix- can I under cook it?
thanks!
VJ cooks
Do you mean you would like to cook if for less time? The shorter your cook it the softer it will be which may be your preference!
Lizzie
Hi there! What is a the ideal size tray to use for this recipe?
VJ cooks
My slice tin is approximately 29 x 19cm. Anything close to this will work. The smaller your tin, the thicker your base will be and the longer it might take to cook. Vice versa for a larger tin.
Vicky Gardner
I’ve over cooked mine and they are super hard is there anyway to repair this?
Vanya Insull
Hi Vicky, hmm... perhaps put a lot of icing on them? Hope you're still able to eat it. 🙂
K
I don’t have white sugar but have raw sugar and caster sugar - which would be the better substitute and would it be the same amount (1 cup)? Thanks!
VJ cooks
I would use the caster sugar. Raw sugar is much chunkier and could take longer to melt in.
