Easy Chocolate Weetbix Slice Recipe (2024)

My slice is crumbly, what’s going on?

There are a couple of reasons:
– You may not have used enough butter for the amount of dry ingredients
– You may not have cooked it long enough, or
– You may have tried to move or cut the slice while it was still warm. The reason for this is the butter is the only liquid holding everything together – there’s no eggs or condensed milk to bind it all. So, while the butter is hot, it’s still in a liquid form. Once it cools, it will set, holding the slice together firmly to keep it’s shape.

My icing is too thick, can it be salvaged?

Yes, add a little extra milk or warm water, 1 teaspoon at a time, to loosen the icing to your preferred texture.

Weetbix Slice Base

  60 g Weetbix biscuits, ¼ cup brown sugar, 1 cup desiccated coconut, 1 cup self raising flour, 2 tbsp cocoa powder

• Pour in themelted butterand mix until well combined. Press the mixture out into a 24 x 24 cm (9 x 9 in) square pan lined with baking paper.

  180 g butter

• Bake for 15 minutes, then remove from the oven and allow to cool down slightly while you make the icing.Tip: Leave the slice in the tin to avoid it crumbling as it cools. If you make the mistake of taking it out while too hot and it crumbles, use a spoon to press it back down while it’s still warm and you’ll be able to salvage it – no stress!

Chocolate Icing

• In a small bowl mix together theicing sugar,cocoa powder,butterandmilkwith a spoon.Tip: Add 1-2 tsp of extra milk or warm water as required to loosen the icing if you find it’s sticking to the spoon instead of the slice and it’s too hard to spread.

  1 cup icing sugar / powdered sugar, 1 1/2 tbsp cocoa powder, 50 g butter, 1 tbsp milk

• Pour icing onto the still warm slice and spread out over the surface using the back of the spoon. Garnish with extra desiccated coconut. Pop into the fridge to cool for at least an hour (or overnight) before slicing. The firmer the slice, the easier it will be to cut without it crumbling!

  2 tbsp desiccated coconut

• Just Use Crumbs –No need to use whole Weetbix biscuits, just save up the crumbly bits from the bottom of your box and store in a jar until you have enough to make this recipe!
• Texture– For a fine crumb texture in the slice, pulse the Weetbix crumbs in a blender or food processor for a few seconds, or crush using a mortar and pestle for extra fun.
• Tray Size– We used our trusty 24 x 24 cm (approx 9 x 9 inch) squarelamingtontray which is about 5 cm (2 inch) deep.
• Bite Size Pieces– This recipe is so moreish, so we recommend slicing into smaller pieces to make it go even further (and you can feel better about eating ‘just one more piece’. 😉
• Storage– Keep in an airtight container in the fridge for up to one week.
