01 - In a mixing bowl, combine powdered sugar, unsalted butter, peppermint extract, heavy cream, and salt. Mix with an electric mixer or sturdy spatula until a smooth, pliable dough forms. Gradually add more powdered sugar if the dough is sticky.
02 - Portion dough into small balls using about 2 teaspoons each. Flatten into 1/4-inch thick discs and arrange on a parchment-lined baking sheet.
03 - Freeze the shaped discs for 20 to 30 minutes until firm.
04 - Place chopped dark chocolate and coconut oil in a heatproof bowl over a pot of simmering water. Stir until the mixture is fully melted and smooth.
05 - Using a fork, dip each chilled peppermint disc into the melted chocolate, allowing excess to drip off. Return to the parchment-lined baking sheet.
06 - Refrigerate the coated patties for 15 minutes or until the chocolate is fully set.
