Rinse the blueberries under cold water and pat them dry with a paper towel. Ensure they are completely dry to help the yogurt adhere better.
In a medium bowl, mix the Greek yogurt, honey (or maple syrup), vanilla extract, and a pinch of salt until well combined.
Line a baking sheet with parchment paper.
Dip each blueberry into the yogurt mixture, ensuring they are fully coated. Use a fork to help lift them out and shake off any excess yogurt.
Place the yogurt-coated blueberries on the prepared baking sheet in a single layer.
Once all the blueberries are coated, place the baking sheet in the freezer for at least 2 hours, or until the yogurt is firm.
After freezing, transfer the blueberries to an airtight container and store them in the freezer for up to 2 weeks.
