Equipment

  • Quarter sheet pan (9x13-inch / 23x33-cm)
  • Parchment paper
  • Medium mixing bowl
  • Flexible spatula
  • Small spoon or skewer

Ingredients

  • 2 cups 454 g Non-fat plain Greek yogurt
  • cup 40 g Shelled unsalted pistachios
  • 4 tsp 20 ml Agave nectar (or honey)
  • 4 tsp 25 g Low-sugar strawberry-rhubarb preserves
  • Zest of ½ a lime
  • tsp Pure vanilla extract
  • tsp Ground cardamom

Instructions

  • Prepare the Pan Line a quarter sheet pan with a sheet of parchment paper, ensuring it lays flat against the bottom and sides to prevent sticking.
  • Toast the Nuts Preheat your oven to 325°F (165°C). Spread the unsalted pistachios on a small baking tray and toast for 5–7 minutes until fragrant. Let them cool completely, then roughly chop.
  • Whip the Yogurt Base In a medium bowl, combine the non-fat Greek yogurt, agave nectar, lime zest, vanilla extract, and ground cardamom. Stir vigorously with a spatula until the mixture is smooth, creamy, and the spices are evenly distributed.
  • Assemble the Bark Pour the yogurt mixture onto the prepared sheet pan. Use the spatula to spread it into a thin, even layer, approximately ¼-inch (⅔ cm) thick.
  • Create the Swirl Drop small dollops of the strawberry-rhubarb preserves randomly over the yogurt layer. Drag the tip of a skewer or a spoon through the dollops to create an elegant, marbled pattern.
  • Add the Crunch Evenly sprinkle the chopped, toasted pistachios over the entire surface of the swirled yogurt.
  • Freeze Until Firm Carefully transfer the pan to the freezer. Let it freeze for at least 2 hours and 30 minutes, or until the bark is completely solid and firm to the touch.
  • Portion and Serve Once frozen, lift the parchment paper to remove the bark from the pan. Break it apart into 24 rustic pieces. Serve immediately.

Notes

  • Storage: Store the frozen bark in an airtight container or a freezer-safe bag for up to 1 month. Place small squares of parchment paper between the layers to prevent the pieces from freezing together.
  • Texture Tip: Allow the bark to sit at room temperature for 1–2 minutes before eating. This softens the yogurt slightly, improving the creamy texture and releasing more flavor.
  • Substitution: If low-sugar strawberry-rhubarb preserves are unavailable, you can mash 1/4 cup of fresh strawberries with a squeeze of lime juice for a fresh fruit alternative.
