Miso Hazelnut Millionaires Shortbread

Nutty hazelnut shortbread topped with smooth miso salted caramel and dark chocolate ganache. An asian spin on the classic millionaires shortbread which may be even better…

One of my favourite desserts growing up in Australia were caramel slices. A layer of shortbread, creamy caramel and a layer of chocolate. It wasn’t until later that I found out the rest of the world had an equivalent, millionaires shortbread. From my research it seems to have originated from Scotland… either way, caramel slice or millionaires shortbread, it’s one of the greatest desserts. These sweets are reminiscent of a Twix bar, but the butteriness of the shortbread in traditional caramel slices takes it to another level. And with the additional hint of miso, and nuttiness of hazelnut, you will love these miso hazelnut millionaires shortbreads!

Why miso in desserts?

Miso desserts have definitely been gaining traction over the years, especially with the increasing popularity of Asian culture and cuisine. This salty fermented bean paste may have seemed strange at first, but the love for its unique salty, umami flavour have taken over. Not only does it add a depth of flavour to sweet desserts, but it also adds an extra silky texture. This makes it perfect in caramel- a hint of salt and extra creaminess to create the caramel of your dreams.

If you haven’t tried miso in a dessert yet, now is the time to give it a go. It might sound weird, but once you have tasted it you’ll be converted!

Tips on creating the perfect millionaires shortbread

There are a couple of tips to creating the perfect slice of caramel shortbread.

  • Spread the shortbread base out with a palette knife
    • Instead of pressing the shortbread out with your fingers use a cranked palette knife to really get into the edges of the cake tin
    • This will help you get an even layer throughout the shortbread, as well as give you the perfect cross-section
  • Chill between layers
    • Chilling the shortbread after you add the caramel ensures a clean distinction between the caramel layer and the chocolate ganache that is layered on top
    • If not chilled sufficiently they could meld together forming a murky chocolate caramel
  • Freeze the shortbread
    • Once fully assembled, giving the shortbread time to freeze will not only make it easier to cut the slices, but also give you clean edges
  • Run the knife under hot water before cutting
    • Running your knife under hot water and wiping of excess in between each slice is what will give you clean, crisp edges on your delicious millionaires shortbread!

    Oh, these look delicious! You have me curious with the miso as an ingredient, it something I have never used to bake with myself. I’m sure it will give the caramel a nice unique slightly salty flavour that normal salt would not give.
