Ingredients
For the Crust & Crumble Topping:
-
1 cup unsalted butter, melted
-
1 cup granulated sugar
-
½ cup light brown sugar
-
1 tsp vanilla extract
-
3 cups all-purpose flour
-
½ tsp baking powder
-
½ tsp salt
For the Huckleberry Filling:
-
3 cups fresh or frozen huckleberries
-
⅔ cup granulated sugar
-
2 tbsp cornstarch

1 tsp lemon zest (optional)
Instructions
1. Preheat & Prep:
-
Preheat oven to 350°F (175°C).
-
Line a 9×13-inch baking pan with parchment paper, leaving an overhang for easy removal.
2. Make the Crust & Crumble:
-
In a large bowl, mix melted butter, both sugars, and vanilla.
-
Stir in flour, baking powder, and salt until crumbly but evenly mixed.
-
Press about 2/3 of the mixture into the bottom of the pan to form a crust. Set aside the remaining 1/3 for the topping.
3. Make the Huckleberry Filling:
-
In a separate bowl, toss huckleberries with sugar, cornstarch, lemon juice, and zest.
-
Spread the berry mixture evenly over the crust layer.
4. Top & Bake:
-
Sprinkle the remaining crumble dough over the berries.
-
Bake for 35–40 minutes, or until the top is golden and the filling is bubbling.
5. Cool & Slice:
-
Let cool completely before slicing into bars. Chill for cleaner cuts.
