Copycat Café Ep. 17: Tru Fru blueberry bark

0 Line a small tray or plate with parchment paper.
1 Spread the blueberries into a single layer, keeping them close together so they'll freeze into one bark.
2 In a small bowl, stir together the Greek yogurt and water until smooth and drizzleable.
3 Drizzle the yogurt evenly over the blueberries.
4 Melt the dark chocolate in the microwave in 20–30 second intervals, stirring between each until smooth.
5 Drizzle the melted dark chocolate over the yogurt layer.
6 If using, drizzle the melted white chocolate over the top and finish with a pinch of flaky sea salt.
7 Freeze for at least 1 hour, or overnight if you want a firmer bark that's easier to break into pieces.
8 Once frozen, break into pieces and enjoy straight from the freezer
