In a spacious mixing bowl, combine the powdered sugar, sweetened condensed milk, unsweetened cocoa powder, peppermint extract, vanilla extract, and a pinch of salt. Use a spatula or wooden spoon to mix the ingredients thoroughly until a thick and smooth dough is achieved.
Once your mixture is well combined, take small spoonfuls and either roll them into bite-sized balls or flatten them into small discs about 1/2 inch thick.
Arrange the formed candies neatly on a baking sheet lined with parchment paper. Place them in the refrigerator for about 30 minutes.
While the candies chill, prepare the chocolate coating. In a microwave-safe bowl, add the dark chocolate chips. Heat in the microwave in 30-second increments, stirring in between sessions, until the chocolate is completely melted and smooth.
After the peppermint creams have chilled, carefully dip each piece into the melted chocolate using a fork or a dipping tool. Ensure each piece is fully coated in chocolate.
Before the chocolate sets, sprinkle each chocolate-covered cream with crushed peppermint candies for an added crunch.
Return the candies to the refrigerator for an additional 15 minutes, or until the chocolate coating has hardened completely.
Notes
Serve on a decorative platter and garnish with extra crushed peppermint candies and fresh mint leaves.
