01 - In a mixing bowl, beat together powdered sugar, unsalted butter, peppermint extract, heavy cream, and salt until a smooth, pliable dough forms. If the mixture remains sticky, gradually incorporate additional powdered sugar until workable.
02 - Scoop out portions of the mixture, about 2 teaspoons each, and flatten into discs approximately 1/4 inch thick. Arrange on a parchment-lined baking sheet.
03 - Freeze the formed discs for 20 to 30 minutes until firm and easy to handle.
04 - In a heatproof bowl set over simmering water, melt dark chocolate and coconut oil, stirring gently until smooth and fluid.
05 - Using a fork, dip each chilled peppermint disc into the melted chocolate, allowing excess to drip off. Return patties to the parchment-lined baking sheet.
06 - Place baking sheet in the refrigerator and chill for 15 minutes or until chocolate is fully set.
