This easy Chocolate Weetbix Slice recipe is perfect for the entire family! All you need is a few simple ingredients and it then takes less than 10 minutes to put this slice together. This Chocolate Weebix Slice makes the perfect treat for the kids lunchboxes and it is also freezer friendly too. Both regular and Thermomix instructions are included.
Whenever I want to make a chocolate treat for the kids, I turn to either my Nan’s Chocolate Cake or this easy Weet-Bix Slice recipe. Both are super simple to make (you only need one bowl to mix it all together), they are freezer friendly (yes, even when iced!) and they satisfy our chocolate cravings.
Why you will love this recipe:
- Quick to prepare – this slice takes around 15 minutes to put together.
- Budget friendly – you will just need a few pantry staples to put this recipe together.
- Freezer friendly – this Chocolate Weetbix Slice can be frozen for up to two months.
- Perfect for Lunchboxes – the kids will love a piece of this slice in their lunchboxes as a special treat!
So while this certainly isn’t the healthiest recipe going around, when it comes to treats, I’d much prefer the kids eat something that we have made versus something we’ve purchased from a store that is full of ingredients we don’t recognise. If you are looking to make this Weet-Bix Slice that little bit better for the kids, then you can easily omit the chocolate icing and just eat it as is.
Weetbix Slice Ingredients:
Please note you will find the full ingredient list and recipe instructions in the recipe card below.
- Weetbix – you will need approximately 12 Weetbix bars for this recipe. You can also use VitaBrix instead.
- Butter – either unsalted or salted butter can be used for this recipe.
- Brown Sugar – caster sugar can also be used, however this will change the consistency of the slice.
- Cocoa.
- Egg
- Desiccated Coconut – I recommend desiccated coconut rather than shredded coconut as it will combine more easily with the other ingredients.
How to Make Chocolate Weetbix Slice:
- Crush the WeetBix bars and set aside until needed.
- Melt the butter.
- Add the crushed WeetBix, brown sugar, cocoa, coconut and egg and mix well.
- Place into a slice tray and bake.
- Once your slice is completely cool, make the icing and spread over the top.
Expert Tips:
- It’s normal for some of the butter to pool on top of the slice when it comes out of the oven.
- It is important to let the slice cool completely before icing or cutting into pieces, otherwise you might end up with a crumbly, chocolate mess. You can place the slice into the fridge or freezer to speed up the cooling process.
- This slice can be served un-iced or you can top it with 100s and 100s, desiccated coconut or leave plain.
- The baked slice can be frozen for up to two months.
