    What You Need

    Have a browse through your pantry and fridge.. you may just find that you already have all the ingredients you need.

    Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method!

    The Ingredients in 6 small bowls on a bench
    • Weet-Bix - these are an iconic Australian and New Zealand breakfast cereal. A similar product can be found in the UK and US called Weetabix.
    • Cocoa powder - use regular unsweetened cocoa powder.
    • Brown sugar - either regular or dark brown sugar can be used for this recipe.
    • Butter - either salted or unsalted is fine to use in this recipe.
    • Dessicated coconut - finely grated, dried coconut that has a coarse powdery texture.
    • Egg - it's best to have your egg at room temperature before using.
    • Milk chocolate - you can use either dark or milk chocolate for this recipe. I like to use either Cadbury or Nestle melts.
    • Coconut oil - this is optional, however using it helps to prevent the chocolate layer on top from cracking when cutting.
    • Freckles - are a chocolate button covered in hundreds and thousands. If you can't find them then it is fine to decorate with just sprinkles, dessicated coconut or just the melted milk chocolate layer on its own.

    Step By Step Instructions

    Five quick and easy steps is all it takes to make this super popular Weet-Bix slice.

    Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method!

    Step 1 - Combine Ingredients

    Crush the Weet-Bix and place all other wet and dry ingredients (not including the chocolate, coconut oil and Freckles for the top layer) into a large bowl.

    Wet and dry ingredients all together in a bowl.

    Step 2 - Mix

    Using a spoon, mix all ingredients together until well combined.

    All ingredients mixed together with wooden spoon.

    Step 3 - Press Into Tin

    Place the mixed ingredients into your prepared slice tin. Press down using a spoon or glass so that it is firm. Bake for 15 to 20 minutes or until firm to touch.

    TIP: Rotate the slice in the oven halfway through cooking to brown evenly.

    Step 4 - Melt Chocolate

    Melt the chocolate and coconut oil (if using) in the microwave or using a double boiler on your stovetop. Spread evenly over the top of the slice.

    Step 5 - Decorate

    Work quickly to place the Freckles on top of the melted chocolate layer.

    Place in fridge to set for at least two hours. Remove from the fridge and allow to sit at room temperature for 30 minutes before cutting into pieces - this helps to prevent the chocolate layer from cracking.

    Expert Tips & FAQs

    Can I make this slice using gluten-free Weet-Bix?

    Yes, you can! I would recommend adding an extra egg to keep it from crumbling.

    Is this Weet-Bix slice a good recipe to make with the kids?

    Absolutely! This is the perfect recipe for kids to help make! It's nice and simple and all made in one bowl. They will love to help decorate it too!

    Why do I need to use coconut oil when melting chocolate?

    The coconut oil helps keep the chocolate slightly softer which makes it easier to cut without the chocolate layer cracking. It's optional, but I do find it makes slicing easier!

    I can't find Freckles in the supermarket. Can I decorate the slice with something else?

    Yes! You can decorate this Weet-Bix slice with hundreds and thousands, or desiccated coconut or even leave it plain. Be adventurous - it's totally up to you!

    What is the best way to cut this slice?

    It's important to let the slice come to room temperature before slicing so take it out of the fridge half an hour before cutting. Using a sharp, hot and dry knife to help cut through the chocolate and stop it from cracking.
    Tip - dip your knife in a cup of hot water then dry.

    Storing

    Store the slice in an airtight container in the fridge for up to 1 week.
    Alternatively, freeze for up to 1 month.

      My girls can't stand weetbix. I didn't want to waste the whole box so I tried this slice without them knowing what's in it. They LOVED it! It's now a weekly school recess slice that I make for them. Super quick, easy, we use Gluten free weetbix and I use Monkfruit sweetener (1/4 cup to maybe 1/2 cup roughly depending how much I have on hand). I find it a very fulfilling slice as the girls eat alot! We just drizzle with dark choc on top mixed with coconut oil and coconut on half the other half plain. 🙂

      Easy and delicious slice that’s not too rich. I’ve made this dozens of times over the years and happy with coconut or freckles toppings. My TM6 makes this even easier with it in the oven in moments! Beautiful recipe ❤️❤️
