Summer! You've stowed your mukluks, pulled out your flip-flops, and you're headed to the shore. Cut out two round cookies from the square bars. Place a dollop of yogurt on one cookie and place in freezer. After five minutes, top yogurt with remaining cookie. Place lollipop stick in yogurt between cookies. Let freeze completely (about 25 minutes). Slather on the sunblock, squeal, and eat.
