1. In a mixing bowl, combine the vegan condensed milk, powdered sugar, and peppermint extract. Stir until the mixture is smooth and pliable.

2. Using your hands, roll the peppermint filling into small balls or shape it into discs. Place the shaped patties on a parchment-lined baking sheet and freeze for 15-20 minutes, or until they are firm.

3. In a heatproof bowl, melt the vegan chocolate with the coconut oil over a double boiler or in the microwave, stirring frequently until the mixture is smooth and glossy.

4. Carefully dip each frozen peppermint patty into the melted chocolate, ensuring that it is fully coated. Return the coated patties to the parchment-lined baking sheet.

5. Allow the chocolate-coated Vegan Peppermint Patties to set at room temperature or in the refrigerator until the chocolate is firm. Once set, you can enjoy these delightful treats immediately or store them in an airtight container in the refrigerator for later.
