01 - In a medium bowl, beat together powdered sugar, softened butter, heavy cream, peppermint extract, and salt until a stiff, smooth dough forms. Adjust consistency by adding a few drops of cream if too dry or more powdered sugar if too sticky.
02 - Lightly dust your hands with powdered sugar. Roll the dough into 1-inch diameter balls and flatten each gently to about ½ inch thickness.
03 - Place the shaped patties on a parchment-lined baking sheet and freeze for 20 to 30 minutes until firm.
04 - Gently melt dark chocolate and optional coconut oil in a heatproof bowl over simmering water or in the microwave in 30-second intervals, stirring until smooth.
05 - Using a fork, dip each chilled peppermint patty into the melted chocolate, allowing excess to drip off. Place back onto the baking sheet.
06 - Refrigerate the coated patties for 20 minutes until the chocolate has fully set.
07 - Keep the finished patties in an airtight container in the refrigerator for up to two weeks.
