Line a baking sheet with parchment paper and spread the Greek yogurt evenly over the surface, smoothing it out with an offset spatula until it's about 1/4 inch thick.
Drizzle honey or maple syrup over the yogurt, then use a spoon or small spatula to gently swirl it in, creating a marbled effect for added sweetness and visual appeal.
Scatter the fresh berries evenly over the yogurt, pressing them lightly into the surface so they stay embedded when frozen.
Sprinkle the chopped nuts and toasted coconut flakes across the top, distributing them evenly for crunch in every bite.
Sprinkle chopped dark chocolate over the toppings for a bittersweet contrast, then place the tray in the freezer.
Freeze the yogurt bark for at least 2 hours, or until completely firm and frozen solid, which helps it snap beautifully when broken.
Once frozen, remove the tray from the freezer and let it sit at room temperature for 5 minutes to soften slightly for easier breaking.
Break the frozen yogurt into jagged shards using your hands or a butter knife, listening for the satisfying crack as it fractures.
Arrange the pieces on a serving platter and enjoy immediately, marveling at the icy crunch and burst of flavors in every bite.
