Line a small baking sheet with parchment paper. Split dates open and press down each one down onto the sheet, making sure they overlap a little so they stick together.
Place a sheet of parchment over the dates and roll flat with a rolling pin.
Drizzle peanut butter on top and use a spoon so spread it evenly over the dates. Sprinkle with chopped nuts.
Melt chocolate with coconut oil and drizzle it over the peanut butter. Use a spoon to spread it evenly to coat the top of the bark.
Sprinkle on flaky sea salt and transfer the baking sheet to the freezer for 10-15 minutes, or until the chocolate has set. Remove from the freezer, chop the bark into pieces and enjoy.
Store leftovers in the fridge or freezer. If you’re storing in the freezer, the dates will get pretty hard so let the bark sit out a few minutes before biting into it.
