1. Line a baking sheet or rimmed tray with parchment paper. This makes it easy to lift the bark once it’s frozen.
2. In a medium bowl, combine the Greek yogurt, honey (or maple syrup), and vanilla extract. Stir until smooth and well mixed. This is where you create that creamy, slightly sweet base that makes the bark so irresistible.
3. Warm the peanut butter slightly in the microwave for about 20 seconds, just enough to make it easier to swirl.
4. Spread the yogurt mixture evenly over the parchment-lined tray, about 1/2-inch thick.
5. Drop spoonfuls of the warmed peanut butter over the yogurt layer. Use a knife or skewer to gently swirl the peanut butter into the yogurt, creating a marbled effect. This step is fun and reminds me of those early kitchen experiments when I’d play with flavors and textures to fix a dish.
6. Sprinkle chopped nuts, chocolate chips, and a pinch of sea salt evenly over the top. The salt enhances the flavor by balancing the sweetness and adding a little crunch.
7. Place the tray in the freezer and let it set for at least 3 hours or until completely firm. I usually make this in the afternoon so it’s ready by snack time.
8. Once frozen solid, break the bark into irregular pieces. Store in an airtight container in the freezer for up to two weeks.

In my experience, the key to great texture here is not rushing the freezing process. Patience pays off with bark that snaps cleanly and holds together well.
