Spread each big solid cookie with frosting and top with a cutout cookie. Sprinkle with powdered sugar. Thaw frozen soft pretzels. Let stand 1 minute. Microwave 20 seconds more if not melted.
Coat pretzels in chocolate.
Insert a stick or skewer in the bottom. Let stand until chocolate is set. Have children mix and pout into cups and freeze. Later when firm, add Popsicle sticks. Yield depends on cup size and age of children.
