Ingredients
Method
- Line a rimmed half-sheet baking pan with parchment paper and smooth it flat against the base and sides.
- In a mixing bowl, stir together the Greek yogurt, honey, vanilla extract, and lemon zest (if using) until fully combined and smooth.
- Pour the yogurt mixture onto the prepared pan and spread it with an offset spatula into an even layer about 1 cm thick.
- Scatter the sliced strawberries, blueberries, and raspberries evenly across the yogurt surface, pressing each piece in gently so it sits flush.
- Sprinkle the granola over the top if using.
- Slide the pan into the freezer uncovered and freeze for 1 hour until the surface is firm, then cover loosely with a second sheet of parchment.
- Continue freezing for at least 3 more hours, or overnight, until the bark is completely solid and does not flex when you lift the edge.
- Remove the pan from the freezer and use your hands or a butter knife to break the bark into irregular pieces. Serve immediately or transfer to a freezer bag with parchment layers between pieces.
Notes
Full-fat Greek yogurt is the key to a creamy texture. Anything less than 5% fat freezes noticeably icier and breaks with a rougher, less even edge.
