Easy, sweet and satisfying on a hot day.
In the bowl of a food processor, puree bananas until smooth. Add yogurt, sugar, and lemon juice; pulse to combine.
Remove half of the yogurt mixture; set aside.
Add blueberries to processor, and pulse until just combined. Layer blueberry and reserved yogurt mixtures into ten 1/3 cup ice-pop molds.
Using a wooden skewer, swirl the two flavors together. Insert ice-pop sticks. Transfer to freezer until frozen, about 8 hours
Dip molds quickly in hot water to unmold.
