An absolute classic and firm family favourite, you will love this easy and delicious version of a Chocolate Weetbix Slice

Chocolate Weetbix Slice

 

I have been making this for absolute years, a handwritten recipe from who knows where! I am sure these classic recipes are the same with a few variations. I assumed all weetbix slices were chocolate but no!

My friends make theirs without the added cocoa, but we love this version and think it’s the best.

This, along with my similar recipe for Cornflake Slice, are firm favourites for lunch box fillers, a simple slice all of the kids and adults enjoy. Over the years this has become the recipe that we teach the kids to make as it is just a matter of adding the wet ingredients to the dry.

When they are young we give them a hand with the melting of the butter but otherwise they love preparing and combining the ingredients.

Dry Ingredients for Chocolate Weetbix Slice

 

A little tip I have when I have melted butter and vanilla in a recipe is to add the vanilla to the butter, this seems to help it infuse throughout the recipe, I love using vanilla essence and always use the Hansells flavoured one.

I know there are fancier versions out there but that is the flavour and smell we love! Not to mention it is reasonably priced! 

Child Baking with Mum, pouring melted butter

 

You can also easily double this recipe, I often make it in my roasting dish, the cooking time only needs to be altered by a further 3-5 minutes, the slice is done when the outside of the slice is starting to harden, but overall it will still appear underdone, it will firm upon cooling.

Spreading a basic chocolate icing

 

For the icing I just use my basic chocolate icing recipe that I use for so many things from slices, cakes to Grandmas Afghans, another GREAT recipe to check out. It is the perfect smooth simple recipe that you will enjoy making time and time again. 

Slice ready to set, dusted in coconut

 

I sometimes dust with coconut, you can also use sprinkles or leave it plain – either way it all tastes good! This does not need to set in the fridge, it can set overnight covered on the bench. Slice once set and enjoy. A great lunch box filler. 

Onto the recipe for Chocolate Weetbix Slice!

  10. Melt the 1 teaspoon butter and add the vanilla and set aside
  11. In a medium bowl add sifted icing sugar and cocoa and stir to combine
  12. Add to this the melted butter and vanilla and stir
  13. Add a teaspoon of water at a time until the consistency is that of smooth peanut butter which you can just drizzle off the end of the spoon
  14. Spread over the slice evenly and if desired sprinkle with a little desiccated coconut to finish
  15. Allow to set overnight, covered on the bench is fine, it does not need to be refrigerated.
  16. Slice once set, serve or store in an airtight container.

    Absolutely loved this stumbling across this recipe. Cooked it with my 4 year old, she really enjoyed crushing the weetbix (anything messy). So delicious, thank you! Took me back to my childhood.

    Thank you for this recipe. I’ve used it a couple of times now and it’s delish. Today I didn’t have enough coconut so I added oats and a bit more weetbix to get the right amount. Perfect with a cuppa.

    Love this one! I don’t wait overnight, usually firms quicker, love how the icing sinks into the base a little too.
