Chocolate hazelnut BLISS ❤️
These bars are THE BEST. The first layer is a baked chocolate slice studded with chocolate chips and roasted hazelnuts (I know right?), next comes a generous smothering of rich dark chocolate ganache.
The final touch? An avalanche of homemade chocolate hazelnut cookie crumbs. All in all, this is one decadent, fudgy chocolate treat.
This recipe was completely unplanned. I had a craving for chocolate slice. I’m a huge fan of nuts and chocolate – hence the reason why I love love love Nutella – and had hazelnuts in the cupboard. Boom, the Chocolate Hazelnut Slice was born.
The chocolate base is actually a perfect all-in-one treat that can be whipped up really fast using regular ingredients. It is perfectly fudgy with crisp edges and pops of chocolate in every bite.
Honestly, you could stop there, but if you are anything like me, you’ll want to make your chocolate slice one to remember.
Enter drippy chocolate ganache (and plenty of it) and LOADS of chocolate hazelnut crumbs. These crumbs are my favourite way to add extra crunch and a pop of flavour to anything. Cakes, cupcakes – you name it. Chocolate hazelnut crumbs are where it’s at.
Reminisenct of a gorgeous brownie, this Chocolate Hazelnut Slice could even been made for a delicious dessert. Leave out the ganache and crumbs, if you want a more portable slice. Either way, you can satisfy your chocolate cravings instantly.
I ate waaay too much of this slice. But it is one of those recipes you can make over and over again. No outrageous ingredients, easy to throw together and unbelievably satisfying.
And those chocolate crumbs are really easy too! A little melted butter is mixed together with a few ingredients, including a handful of crushed roasted hazelnuts, and then baked to perfection. Once the crumbs cool, they become little crunchy cookies – my fav!
So tell me, how was your weekend? We went to Palm Beach yesterday and walked up to the Barrenjoey Head Lighthouse. Man oh man, what a truly stunning part of the world! I shared some photos on my Insta Stories.
This week I’m going to be at the studios for work cooking up a storm and then my mum is coming to visit for Mother’s Day – I can’t wait! Speaking of, this slice would be perfect for a sweet Mother’s Day morning tea.

- Melt your butter and add it to the mixture, stirring until it forms wet crumbs. Pour this mixture out onto a baking tray lined with baking paper and spread out into one layer. Bake for 10 minutes, then leave to cool completely.
- To make the chocolate ganache, roughly chocolate dark chocolate and add to a small bowl. Pour over the cream and the pop in the microwave for 20 second bursts, stirring in between, until chocolate has melted. Put the ganache in the fridge for about 15 minutes to thicken.

Hey, this looks ridiculous!!! Thanks for sharing. I was wondering whether you think it would be good to make as a round cake for my friends birthday?
Jessica Holmes says
Hi Jess! It really is delicious! You could definitely bake it in a round tin instead. It’s not a cake, more like a cookie, but I’m sure your friend would like it! 🙂
