Place parchment paper on a baking sheet to prevent sticking and make for easy removal.
In a mixing bowl, combine Greek yogurt with vanilla extract (if using plain yogurt) and stir until smooth and fully blended.
Using a spoon, place 2-3 tablespoon-sized dollops of the yogurt mixture onto the prepared baking sheet, leaving space between them for easy handling.
Evenly top each yogurt dollop with blueberries, sliced strawberries, and a sprinkle of granola.
Transfer the baking sheet to the freezer and freeze for 2-4 hours, or until the yogurt is fully frozen and firm.
Once frozen, remove from the freezer and enjoy right away, or store in an airtight container or freezer bag for up to 2 weeks in the freezer.
