Line your pan. Cover a rimmed baking sheet with parchment. This makes it easy to lift and break the bark later.
Mix the base. Stir the dairy-free yogurt with 1–2 tablespoons maple syrup, vanilla, and a pinch of salt.
Taste and adjust sweetness. The mixture should be slightly sweet but not cloying.
Spread it out. Pour the yogurt onto the lined sheet and spread into an even layer about 1/4 inch thick. Thicker layers take longer to freeze; thinner ones get extra snappy.
Add the berries. Scatter mixed berries evenly over the yogurt.
If using large strawberries, slice them thin so they freeze and bite easily.
Sprinkle granola. Add an even layer for crunch. Press lightly so it adheres without sinking too deep.
Drizzle. Warm the maple syrup slightly if it’s thick, then drizzle in thin ribbons over the top. A gentle zigzag adds flavor and looks great.
Freeze. Place flat in the freezer for 2–4 hours, or until completely firm.
Break and serve. Lift the bark out by the parchment and snap into pieces.
Enjoy right away, or store for later.
