Ingredients

Scale
  • 1 1/2 cups (190g) all-purpose flour
  • 1/3 cup (67g) granulated sugar
  • 1/4 teaspoon salt
  • 3/4 cup (170g) unsalted butter, cold and cubed
  • 2 cups (300g) huckleberries, fresh or frozen
  • 1/2 cup (100g) granulated sugar
  • 1 tablespoon lemon juice
  • 1 tablespoon cornstarch
  • 1/2 cup (115g) unsalted butter (for browning)
  • 1 1/2 cups (135g) old-fashioned rolled oats
  • 1/2 cup (100g) light brown sugar
  • 1/2 cup (65g) all-purpose flour
  • 1/2 teaspoon ground cinnamon
  • Pinch of salt

Instructions

  1. Prepare the crust: In a large bowl, whisk together flour, granulated sugar, and salt. Add cold, cubed unsalted butter. Use a pastry cutter or fingers to work butter into flour until mixture resembles coarse crumbs with some pea-sized chunks, about 5 minutes.
  2. Press the crust mixture evenly into the bottom of a greased 9×9 inch baking pan to about 1/2 inch thickness. Bake at 350°F (175°C) for 15 minutes or until lightly golden around edges.
  3. Make the huckleberry filling: In a bowl, combine huckleberries, granulated sugar, lemon juice, and cornstarch. Toss gently to coat and set aside to macerate while crust bakes.
  4. Brown the butter: In a small saucepan over medium heat, melt butter, stirring frequently until it foams and turns golden brown with a nutty aroma, about 5 minutes. Remove from heat and cool slightly.
  5. Prepare the oat topping: To the browned butter, add rolled oats, light brown sugar, flour, cinnamon, and a pinch of salt. Mix until combined and crumbly.
  6. Assemble the bars: Remove crust from oven. Spread huckleberry filling evenly over warm crust. Sprinkle brown butter oat topping evenly over berries, pressing gently to adhere but leaving some texture.
  7. Bake bars at 350°F (175°C) for 25-30 minutes until topping is golden and filling bubbles around edges. Topping should feel set but slightly chewy.
  8. Cool bars completely on a wire rack for at least 2 hours to set filling. For easier slicing, chill in fridge for 30 minutes before cutting into squares.

Notes

Use a light-colored saucepan to brown butter to better monitor color change and avoid burning. Keep butter cold when mixing crust for flakier texture. Do not press oat topping too firmly to maintain crumbly texture. Cool bars completely before slicing to avoid mess. Frozen huckleberries can be used but should be thawed and drained. For gluten-free, substitute all-purpose flour with almond flour. For dairy-free, use coconut oil instead of butter and skip browning step.
