In the bowl of a stand mixer, mix/mash the banana until smooth.
Add the yogurt and milk, mixing until the ingredients are evenly incorporated and the mixture is smooth. Use a spatula to gently stir in the cereal, just until evenly dispersed. Using the mixer may crush the cereal.
Transfer the mixture into popsicle molds, and freeze for 8 hours, or until frozen solid.
Run warm water over the molds for a few seconds to release the frozen pops.
