Take the old-school hedgehog and add all manner of chocolate shards, wedges of caramel along with malt and choc chunk biscuits and the odd random swirl of dulce de leche. You can go as high- or as low-brow as you like in terms of ingredients. It all tastes good. It's important not to use really hard caramels; use a soft version, such as those supermarket aisle Cadbury caramels, that won't break teeth after this slice has spent time hardening in the fridge.
320g caramels, roughly chopped into bite-sized pieces
200g milk chocolate, cut into rough chunks
125g Malt 'O' Milk biscuits (or any malted milk biscuits), roughly broken
250g chocolate chip biscuits, roughly broken
¼ cup dulce de leche
350g dark chocolate (I used 70 per cent), broken into squares
295g can condensed milk
1. Line a lamington tin (about 30cm x 20cm x 3cm) with baking paper, making sure it hangs generously over the sides to make lifting the slice out nice and easy.
2. Place the caramels, milk chocolate chunks, Malt 'O' Milk biscuits and chocolate chip biscuits in a bowl and use your hands to gently toss and combine. Add the dulce de leche, just in spoonfuls here and there, don't try and incorporate it.
3. Add the dark chocolate to a heatproof bowl and place over a pot of simmering water, making sure the water doesn't touch the bowl. Cook until the chocolate has melted.
4. Remove from heat and pour in the condensed milk, whisking constantly to prevent the chocolate from seizing. Once the mixture has thickened, quickly pour this over the biscuit and caramel mix, stirring with a wooden spoon to coat. Scrape the mixture into the prepared tray, smoothing out the top as best you can.
5. Place in the fridge for at least 2 hours to set. Remove and allow to sit at room temperature for 30 minutes before slicing, or use a hot, wet knife to slice immediately.
Note: This will keep in an airtight container in the fridge for up to 3 weeks, if any of it lasts that long.
