05 - Pour the melted chocolate over the base and spread evenly with a spatula.
06 - Immediately sprinkle with chopped pistachios, toasted coconut flakes, and a pinch of flaky sea salt if desired.
07 - Refrigerate the pan for at least 45 minutes or until the chocolate is fully set.
08 - Once set, use the parchment to lift the slab out of the pan. Slice into 16 bars using a sharp knife.
