Peel the kiwis and slice them thinly into rounds, about ½ cm thick.
Line a baking sheet with parchment paper and arrange the kiwi slices in a single layer.
Sprinkle the shredded coconut evenly over the kiwi slices — this helps absorb moisture so the chocolate sticks, as kiwis naturally hold a lot of water.
Melt the dark chocolate in a heatproof bowl over a pot of gently simmering water (or in short microwave bursts).
Pour or drizzle the melted chocolate evenly over the kiwi slices, covering them completely.
Drizzle pistachio butter over the top, then scatter with chopped pistachios and goji berries (or your preferred toppings).
Place in the fridge for about 20–30 minutes, or until the chocolate has fully set.
Once firm, break or chop into shards. Store in the fridge and enjoy straight from cold for the best texture.
