Line your tray: Line a baking sheet or large plate with parchment paper. Make sure it fits flat in your freezer.
Mix the base: In a bowl, stir together the Greek yogurt, honey, vanilla, lemon zest (if using), and a pinch of salt until smooth and creamy.
Fold in blueberries: Gently fold in the blueberries. If using frozen blueberries, work quickly so they don’t bleed too much color.
Add crunch: If you like texture, fold in chopped nuts or granola, or save it to sprinkle on top.
Scoop the bites: Use a small cookie scoop or spoon to drop 1–2 tablespoon mounds onto the parchment, spacing slightly apart.
Sprinkle with any remaining crunchy bits.
Freeze: Freeze until solid, about 1.5–2 hours. For a slightly softer center, check them at 75–90 minutes.
Store: Transfer the frozen bites to a freezer-safe container or zip-top bag with parchment between layers. Label and date.
Serve: Let sit at room temperature for 2–4 minutes before eating for the best creamy texture.
