Prepare the Peppermint Filling: In a large mixing bowl, combine powdered sugar, creamy peanut butter, and peppermint extract. Mix well until smooth. Chill the filling in the refrigerator for 30 minutes.

Shape the Patties: Roll the chilled filling into small balls or flatten into discs about ¼ inch thick. Chill for another 15 minutes.

Melt the Chocolate: In a microwave-safe bowl, heat dark chocolate in 30-second intervals, stirring until fully melted, about 1-2 minutes total.

Dip the Patties: Dip each patty into the melted chocolate, ensuring full coating, and place back on the tray to set.

Add Optional Garnish: Sprinkle toppings before the chocolate sets for a festive touch.

Cool and Harden: Allow the chocolate-covered patties to harden at room temperature for about 30 minutes or refrigerate for quicker setting.
