Why We Love This

Just like chester squares, chocolate concrete or Scottish tablet, this is a classic retro treat guaranteed to bring a hit of nostalgia.

The flavour in this Aussie crunch is like a combination between honey joys and chocolate crackles. It reminds us of being kids and eating all the sweet things from school fetes or going to our grandma’s and gorging on scones or coffee scroll biscuits.

We love the quick prep of 5 minutes to get this in the oven. That’s more time to chill with a cup of tea while it bakes away! We also love the creamy chocolate topping that offsets against the crunchy base so well!

What is Aussie Crunch? 

Aussie Crunch, also known as Australian Crunchies or Ozzy Crunch, is a chocolate coconut slice topped with creamy Cadbury chocolate.

Melted butter and golden syrup bind together the crushed cornflakes and coconut for the ultimate crispy yet slightly chewy chocolate slice.

Crazily enough, Aussie crunch is not an Australian recipe, but actually from Northwest England. It’s especially popular in the Bolton area, served anywhere from the school canteen to bakeries and sandwich shops.

If anyone does know how it came by the name of Aussie Crunch – pop it in the comments below. We’re curious, and through all the research, we couldn’t really find a definitive answer.

Aussie crunch is not to be confused with chocolate concrete which is sometimes called chocolate crunch. Chocolate concrete is a drier cake, almost like a brownie and a biscuit, and often served with custard.

What You’ll Need

Only 8 super easy baking ingredients are needed for this recipe, with plenty of substitutions available to make them with what you have in the pantry.

  • Butter – We used salted butter, but you can also use unsalted or margarine.
  • Self Raising Flour – If you don’t have self raising flour, sub with all purpose flour along with 1 tsp of baking powder and ½ tsp of baking soda.
  • Golden Syrup – This gives the slice a real caramelised taste along with the butter. You can also use honey, treacle, brown sugar or molasses as alternatives.
  • Caster Sugar – Any white sugar will work, or you can also use brown sugar.
  • Cornflakes – Crushed cornflakes make up the traditional crunchy base, but you can easily swap them for rice bubbles or weetbix.

Wandercook’s Tips

  • Storage – Keep them in the fridge in an airtight container for up to a week. You can also cut them up into bite size pieces and freeze them. Perfect for snacks or lunch boxes just when you need it most!
  • Crushing Cornflakes – Use the back of a spoon to crush your cornflakes in a bowl. Or pop them in a bag and crush them up by hand.
  • Triangles – We’ve been told these MUST be cut into triangles, but we won’t tell anyone if you decide to leave them as squares or long slices!
  • Low Heat – Low heat is key, as it helps to melt and bind everything together without burning it.

FAQs

Can I batch or freeze Aussie crunch?

Yes, you can easily double or triple the recipe if needed. We recommend cooking in a few separate baking trays so the slices aren’t too thick. Once cooked, cut them into portions first, then seal in an airtight container and pop in the freezer.

Is Aussie Crunch an Australian recipe?

The origin of Aussie crunch seems to have originated in England, and not Australia.

    I love making this recipe. My old boss introduced it to me. He used to occasionally put mint icing in between the corn flake /coconut base and chocolate. Delicious either way (my old boss is a chef and baker)

      Hey Kath, thanks for letting us know! Oh that is quite the decadent idea to pop in a layer of mint icing. We’d definitely be keen to give that a go with the next batch. We’ll have to pop it in the notes for others to try!

          Hey Gina, it should be roughly 90g, the cup amount listed is before crushing the cornflakes. Whichever method you prefer (cups or grams) it will work out fine, it doesn’t have to be exact for this recipe. Enjoy! 🙂
