Slice the bananas into 1/2-inch coins for consistent sizing—this ensures even texture throughout your bites and helps them freeze uniformly. In a large bowl, combine the vanilla Greek yogurt, honey, sliced bananas, and blueberries. Gently fold everything together until the bananas are partially broken down and distributed throughout the yogurt, creating a creamy base with fruit pieces. I prefer to leave some banana chunks rather than mashing them completely—it gives the final bites a better texture and makes them feel less dense.

In a separate small bowl, combine the strawberry Cheerios and regular Cheerios together—mixing them before folding into the yogurt helps distribute the fruity and plain cereals evenly. Gently fold the cereal mixture into the yogurt base from Step 1, being careful not to crush the cereal and lose the crunch. Divide the mixture evenly among small cups or silicone ice cube molds, filling them to the top and gently pressing down with the back of a spoon to pack the mixture without compressing it too much. I like using small paper cups or silicone molds because they're easy to peel away when serving, and the frozen bites pop out cleanly.

Transfer the filled cups or molds to the freezer and freeze overnight or until completely solid (at least 8 hours). Once frozen solid, the bites are ready to eat straight from the freezer. They'll have a soft-serve frozen yogurt texture on the outside with crunchy cereal pieces throughout.
