Line a baking sheet with parchment paper for easy removal.

In a mixing bowl, combine the Greek yogurt with the vanilla extract (if using plain yogurt). Mix well until smooth.

Using a spoon, drop 2-3 tablespoon dollops of the yogurt mixture onto the prepared baking sheet, spacing them apart.

On each yogurt dollop, evenly distribute blueberries, sliced strawberries, and a sprinkle of granola.

Place the baking sheet in the freezer and freeze for at least 2-4 hours or until the yogurt is fully frozen and firm.

Once the yogurt bites are completely frozen, remove them from the freezer. Enjoy them immediately, or store them in an airtight container or freezer bag in the freezer for up to 2 weeks.
