Prep your pan: Line a baking sheet or 9x13 pan with parchment. Leave some overhang so you can lift the bark out later.
Blend the base: Add cottage cheese, Greek yogurt (if using), sweetener, vanilla, salt, and protein powder (if using) to a blender or food processor. Blend until completely smooth and creamy, 30–60 seconds.
Scrape down the sides once to catch any curds.
Taste and adjust: Sweeten a little more if needed. The flavor dulls slightly once frozen, so make it just a touch sweeter than you think.
Spread it out: Pour the mixture onto your lined pan. Use a spatula to spread it evenly about 1/4–1/3 inch thick.
Thinner bark freezes faster and snaps more easily.
Add toppings: Scatter berries across the surface. Gently press them in. Sprinkle on nuts, granola, or cacao nibs for crunch.
Melt and drizzle chocolate: Microwave chocolate in 15–20 second bursts, stirring between each, until smooth.
Drizzle over the top in thin ribbons or swirl with a toothpick.
Freeze: Place the pan flat in the freezer for 2–3 hours, or until firm all the way through.
Break into pieces: Lift the bark out by the parchment. Snap into shards or cut into squares with a sharp knife.
Serve: Enjoy straight from the freezer for the best texture. If it’s too firm, let it sit at room temperature for 1–2 minutes.
