Prepare popcorn according to package directions. Remove all unpopped kernels. Place popcorn in large bowl; set aside.
Spray 2 large baking sheets with cooking spray. Arrange 21 groups of three pecan halves in cloverleaf pattern on baking sheet.
Place caramels, Fleischmann’s, and milk in microwave-safe bowl; microwave on HIGH 3 to 4 minutes or until caramels are melted, stirring once. Pour over popcorn; gently toss to evenly coat. Allow to cool 2 minutes.
Spray hands with cooking spray. Shape popcorn into 1-inch mounds; press onto center of each pecan cloverleaf.
Melt chocolate morsels in microwave on HIGH for 2 minutes or until smooth when stirred. Drizzle over each caramel mound. Chill 1 hour or overnight.
