Ingredients Equipment Method Notes

Ingredients
  

  • 200 g dark chocolate 70% cocoa recommended
  • 1 cup mixed nuts almonds, walnuts, hazelnuts, toasted
  • 1/4 cup honey or golden syrup
  • 2 tbsp coconut oil unrefined preferred
  • 1/4 tsp flaky sea salt plus extra for sprinkling
  • 1 tsp vanilla extract

Equipment

  • 20cm (8-inch) square baking dish
  • parchment paper
  • Mixing bowl
  • Spatula
  • Microwave
  • Skillet
  • Sharp knife

Method
 

  1. Chop the dark chocolate into small, even pieces and place in a microwave-safe bowl. Microwave in 30-second bursts, stirring well each time, until the chocolate is melted and glossy. This should take about 1-2 minutes.
  2. While the chocolate melts, toast your mixed nuts in a dry skillet over medium heat for about 5 minutes, stirring frequently. The nuts will become fragrant and slightly smoky—this enhances their flavor and crunch. Remove from heat and let cool slightly.
  3. Add honey or golden syrup, coconut oil, and vanilla extract to the melted chocolate. Mix thoroughly until the mixture is smooth, shiny, and well combined. The warmth of the melted chocolate will help melt the coconut oil and blend everything seamlessly.
  4. Fold in the toasted nuts and a pinch of flaky sea salt into the chocolate mixture, ensuring they are evenly coated and distributed. The mixture will begin to look chunky with bits of nuts throughout.
  5. Line your square baking dish with parchment paper, leaving some overhang for easy removal. Pour the chocolate-nut mixture into the dish and press down firmly with the back of a spatula to create an even layer. This helps the slice set tightly and prevents air pockets.
  6. Sprinkle a little extra flaky sea salt on top for added flavor. Place the dish in the fridge and chill for at least 2 hours, or until the mixture is firm and set. For quicker results, you can freeze it for about 30 minutes, but avoid over-freezing to prevent cracking.
  7. Once the slice has set, lift it out using the parchment overhang. Use a sharp knife to cut into squares or rectangles, cleaning the blade between cuts for neat edges. Serve immediately or store in the fridge until ready to enjoy.
  8. Enjoy your rich, crunchy, no-bake chocolate nut slice—perfect for sharing or gifting! Keep leftovers refrigerated in an airtight container for up to 5 days for optimal freshness.

Notes

For added flavor, sprinkle extra sea salt on top before chilling. You can also customize with different nuts or a drizzle of caramel for extra decadence.
