01 - In a mixing bowl, combine powdered sugar, unsalted butter, peppermint extract, heavy cream, and salt. Beat until the mixture forms a smooth, pliable dough. If the dough is too sticky, incorporate additional powdered sugar in small increments until workable.
02 - Scoop 2 teaspoons of dough per piece and shape into balls. Flatten each ball to 1/4-inch thickness and arrange on a parchment-lined baking sheet.
03 - Transfer baking sheet to the freezer and chill the discs for 20 to 30 minutes until firm to the touch.
04 - In a heatproof bowl set over simmering water, melt dark chocolate with coconut oil, stirring until glossy and completely smooth.
05 - Using a fork, dip each chilled peppermint disc into the melted chocolate. Allow excess chocolate to drip off before returning to the parchment-lined sheet.
06 - Place tray in the refrigerator for 15 minutes or until chocolate coating is fully set.
