01 - Using a sharp knife, slice each date lengthwise on one side and carefully remove the pit, keeping the date as whole as possible.
02 - Fill each pitted date with approximately 1/2 tablespoon of creamy peanut butter. Gently press the dates to enclose the filling.
03 - Combine the dark chocolate and coconut oil (if using) in a heatproof bowl. Melt the mixture over simmering water or microwave in 20-second increments, stirring until smooth and glossy.
04 - Dip each filled date into the melted chocolate, ensuring a complete coating. Use a fork to lift the coated dates, allowing any excess chocolate to drip off.
05 - Arrange the chocolate-covered dates on a parchment-lined baking tray. While the coating is still wet, sprinkle with chopped roasted peanuts and flaky sea salt if desired.
06 - Chill the tray of dates in the refrigerator for 10 minutes or until the chocolate is fully set.
07 - Present dates chilled from the fridge or at room temperature for best flavor and texture.
