Prep your pan: Line a rimmed baking sheet or 9x13-inch pan with parchment paper. Make sure it overhangs on two sides so you can lift the bark out easily.
Toast the almonds: In a dry skillet over medium heat, toast sliced almonds for 3–4 minutes, stirring often, until golden and fragrant.
Let them cool.
Mix the base: In a bowl, whisk the Greek yogurt with honey (or maple), vanilla, almond extract (if using), and a pinch of salt until smooth and evenly sweetened. Taste and adjust sweetness.
Spread the yogurt: Pour the yogurt mixture onto the lined pan. Use a spatula to spread it into an even layer, about 1/4 inch thick.
Thinner layers freeze faster and are easier to snap.
Add the cherries: Scatter the chopped cherries evenly over the yogurt. If using frozen cherries, pat them dry first to reduce ice crystals.
Sprinkle the crunch: Add the toasted almonds over the top. If you like, add mini chocolate chips, lemon zest, or coconut for extra flavor and texture.
Freeze: Transfer the pan to the freezer and freeze for 2–4 hours, or until completely solid.
Break into pieces: Lift the bark out using the parchment.
Break into shards or cut into squares with a sharp knife.
Store: Place the pieces in an airtight container with parchment between layers. Keep frozen until ready to eat.
