Ingredients

Scale
  • 1 ½ cups (180g) all-purpose flour
  • 1 cup (90g) rolled oats
  • ½ cup (100g) granulated sugar
  • ½ cup (110g) unsalted butter, cold and cut into cubes
  • ½ teaspoon ground cinnamon (optional)
  • ¼ teaspoon salt
  • 3 cups (450g) wild huckleberries (fresh or frozen, thawed and drained)
  • ½ cup (100g) granulated sugar
  • 1 tablespoon lemon juice
  • 1 tablespoon cornstarch
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan lightly or line it with parchment paper.
  2. In a large bowl, combine 1 ½ cups flour, 1 cup rolled oats, ½ cup sugar, ½ teaspoon cinnamon, and ¼ teaspoon salt. Toss together.
  3. Cut the ½ cup cold, cubed butter into the dry ingredients using a pastry cutter or two forks until the mixture resembles coarse crumbs with some pea-sized bits.
  4. Press two-thirds of the crumble mixture into the bottom of the pan firmly and evenly.
  5. In a separate bowl, gently toss the wild huckleberries with ½ cup sugar, 1 tablespoon lemon juice, 1 tablespoon cornstarch, and 1 teaspoon vanilla extract until evenly mixed.
  6. Spread the berry filling evenly over the crust without overfilling.
  7. Crumble the reserved oat mixture over the berry layer, breaking into smaller chunks if needed.
  8. Bake for 40-45 minutes until the top is golden brown and the filling is bubbly. Tent with foil halfway through if edges brown too fast.
  9. Cool completely on a wire rack to allow the filling to set.
  10. Cut into 16 squares and serve.

Notes

Keep the butter cold to maintain a flaky, crumbly texture. Drain frozen berries well to avoid soggy bars. Tent with foil if streusel browns too quickly. Cool completely before cutting to prevent runny filling. For gluten-free, use gluten-free flour and oats. For dairy-free, substitute butter with coconut oil.
