Mix together in a bowl 1 cup of the vanilla yogurt with half the raspberries and blueberries. Use an immersion blender or a muddler to incorporate the fruit and yogurt.

Layer the ingredients in a popsicle mold starting with a spoonful or two of vanilla yogurt, followed by granola, a few fresh berries and a layer of the mixed yogurt. Sprinkle a final layer of granola before inserting the popsicle sticks. Freeze for at least four hours.

To remove the popsicles from the mold run them under hot water for a few seconds until they slide easily out of the mold.
