01 - Preheat oven to 350°F. Arrange almonds evenly on a baking sheet and toast for 8 to 10 minutes, stirring once halfway through, until fragrant. Allow almonds to cool completely.
02 - On the same baking sheet, spread out shredded coconut in an even layer and toast for 3 to 4 minutes, watching closely, until golden brown. Set aside and let cool.
03 - In a microwave-safe bowl or using a double boiler, melt chopped dark chocolate and optional coconut oil in 30-second intervals, stirring after each, until smooth and fully melted.
04 - Stir toasted almonds and toasted coconut into the melted chocolate mixture until all pieces are thoroughly coated.
05 - Line a baking sheet with parchment paper. Drop heaping tablespoons of the chocolate mixture onto the lined sheet, spacing them apart.
06 - Sprinkle each cluster with a pinch of sea salt, if desired. Transfer baking sheet to the refrigerator and chill for at least 30 minutes or until clusters are firm.
07 - Store finished clusters in an airtight container in the refrigerator for up to 2 weeks.
