Line 12-cup muffin pan with parchment paper cupcake liners.
Microwave chocolate chips or melting chocolate in medium microwave-safe bowl at HIGH, stirring occasionally, 1-1/2 minutes or until smooth. Spoon chocolate by rounded tablespoonfuls into cupcake liners, then with back of small spoon spread chocolate to completely coat sides and bottoms. Refrigerate 30 minutes or until firm.
Carefully peel and discard parchment from chocolate cups. Arrange chocolate cups on dessert plates. Fill each with 1 scoop of your favorite Breyers flavors and spread gently to fill the chocolate cup.
Pipe or spread whipped topping over the top of the Breyers and decorate with festive toppings (sprinkles, chocolate hearts, etc).
