In a bowl, combine confectioners’ sugar, cream cheese and peppermint extract. Beat at low speed, scraping bowl often, until smooth and creamy. Gently stir in whipped cream and crushed candies. Spread evenly over chocolate layer. Sprinkle with additional crushed candy, if desired. Freeze for 4 hours or overnight.

To serve, cut into squares. Top each square with a candy cane (if using). Serve frozen or refrigerated. Store frozen.

TIP: To crush candy, place in resealable plastic food bag and pound with a rolling pin or meat mallet, checking often to make sure you don’t pulverize the candy.
