Insert a wooden popsicle stick into the cut end of each banana piece. Dip each in yogurt to coat. Sprinkle with cereal to coat. Arrange on a parchment paper-lined tray. Cover and freeze until firm. Let stand at room temperature 10 minutes to soften, if necessary.
Grab and go on the way out the door or place on tray in the morning for guests or your kids to enjoy.
