Start by lining a brownie tin (20cm/8"x20cm/8"x6cm/1.5") with greaseproof non-sick paper and set to one side.
Drain and rinse your soaked cashews until the water runs clean. Be sure to shake off as much moisture as possible. Place all of your nougat ingredients into a food processor and blend into a smooth paste. Scrape down the sides frequently. Spoon the nougat into the lined brownie tin and press in your nougat layer, flattening with your hands until evenly distributed. Place into the freezer until firm.
Place all of the ingredients for your caramel into the bowl of your food processor and blend into a smooth paste, scraping down the sides in ensuring a smooth mixture. Remove your nougat from the freezer and spoon over your caramel. Using a damp offset spatula smooth over the caramel until you have an even layer. Smooth out any bumps with damp fingertips or oil your hands with some coconut oil to prevent the caramel from sticking. Place your brownie tin into the freezer for 30 minutes until firm.
Place your raw chocolate ingredients over a bain-marie/double boiler (do not let the bowl touch the water) on a low heat and melt the ingredients until fully combined. Be sure to give a good stir and set to one side.
Remove your nougat and caramel from the freezer. Carefully lift out your block of caramel and nougat. Cut into 8 equal pieces or if you'd prefer 16 even bite-sized pieces.
Dip your bars into the melted chocolate using a fork. Tap the fork onto the bowl to remove any excess chocolate and place onto a baking tray lined with either a silicone mat or greaseproof paper. Repeat the dipping process 2-3 times and then place the bars in the fridge/freezer until set.
Store in an airtight container within the fridge and consume within 1 week. Alternatively, freeze and consume within 4-6 weeks.
