Step 1

INGREDIENT INFO: Unsweetened flaked organic coconut is available at natural foods and specialty foods stores.

Step 2

Preheat oven to 350°. Spread out coconut on a rimmed baking sheet and toast, stirring occasionally, until most flakes are straw-colored, about 4 minutes. Transfer to a plate.

Step 3

Meanwhile, line a baking sheet with a silicone baking mat or parchment paper. Melt the chocolate in a double boiler or in 30-second intervals in a microwave, stirring between each interval. Spread melted chocolate on baking mat in an even layer about 1/8" thick. Scatter toasted coconut, pistachios, and cacao nibs evenly over chocolate. Sprinkle with flaky sea salt, if using. Let chocolate cool completely, then break into pieces. Bark will keep for about a week stored in a cool place in an airtight container between layers of parchment.
