01 - Slice each date lengthwise on one side and remove the pit if not already pitted.
02 - Fill each date with about 1/2 tablespoon of almond butter, then gently press closed.
03 - Melt the dark chocolate and coconut oil together in a heatproof bowl over a pot of simmering water (double boiler) or in the microwave in 20-second bursts, stirring until smooth.
04 - Using a fork, dip each stuffed date into the melted chocolate until fully coated. Let excess chocolate drip off, then place the dates on a parchment-lined baking sheet.
05 - Immediately sprinkle with chopped almonds and flaky sea salt, if using.
06 - Refrigerate for at least 20 minutes, or until the chocolate is set.
07 - Serve chilled or at room temperature.
