01 - Line a baking tray with parchment paper.
02 - Gently open each date lengthwise without cutting completely through.
03 - Fill each date with about 1/2 tablespoon almond butter, then pinch closed carefully.
04 - Combine dark chocolate and coconut oil (if using) in a heatproof bowl over simmering water or microwave in 30-second intervals, stirring until smooth.
05 - Using two forks, dip each stuffed date into melted chocolate to cover completely, letting excess drip off before placing on the prepared tray.
06 - Sprinkle chopped almonds and flaky sea salt over the wet chocolate, if desired.
07 - Refrigerate for 20 minutes until chocolate is firm.
08 - Serve chilled or at room temperature. Store leftovers in an airtight container in the refrigerator for up to one week.
