Ingredients & Their Roles

For the Crust & Crumble Topping

• 2 cups all-purpose flour – Forms the structure of the crust and the crumble topping.
• 1 cup old-fashioned oats – Adds hearty texture and enhances the crumble’s buttery crunch.
• 1 cup granulated sugar – Sweetens both layers evenly without overpowering the berries.
• 1/2 cup light brown sugar – Adds depth, moisture, and a subtle caramel note.
• 1 teaspoon baking powder – Helps the crust bake tender instead of overly dense.
• 1/4 teaspoon salt – Balances sweetness and enhances the berry flavor.
• 1 cup unsalted butter, melted – Creates a rich, golden crust and binds the crumble mixture.
• 1 teaspoon vanilla extract – Infuses warmth and enhances the shortbread-like base.

For the Mixed Berry Filling

• 4 cups mixed berries (fresh or frozen) – Blueberries, raspberries, blackberries, and strawberries all work beautifully.
• 1/2 cup granulated sugar – Sweetens the berries while keeping their natural tartness.
• 2 tablespoons cornstarch – Thickens the berry juices, creating a luscious jam-like layer.
• 1 tablespoon lemon juice – Brightens the filling and enhances the fruit’s natural flavor.
• 1 teaspoon lemon zest – Adds a fresh, fragrant citrus aroma.

Step-by-Step Instructions

1. Prepare the Pan

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, ensuring the edges hang over for easy removal.
This guarantees clean, perfect slices every time.

2. Make the Crust & Crumble

In a large mixing bowl, combine the flour, oats, granulated sugar, brown sugar,
baking powder, and salt. Stir until evenly blended.
Pour in the melted butter and vanilla extract, mixing until the mixture resembles coarse, buttery sand.

Press two-thirds of the mixture firmly into the bottom of the prepared pan.
This forms the sturdy, tasty base that holds up the berry filling.

3. Prepare the Berry Filling

In another bowl, add your mixed berries, then sprinkle with the granulated sugar, cornstarch,
lemon juice, and lemon zest. Gently toss until the fruit is evenly coated.
This step ensures the berries cook into a thick, jammy layer without becoming runny.

4. Assemble the Bars

Spread the berry mixture evenly over the crust. Then sprinkle the remaining crumble mixture over the top.
You want some clusters and some finer crumbs for the perfect texture.

5. Bake to Perfection

Bake for 40–45 minutes, or until the top is golden brown and the berry layer is bubbling slightly around the edges.
The scent alone will be heavenly—warm berries, buttery crumble, and hints of vanilla.

6. Cool & Slice

Allow the bars to cool completely before slicing. This helps the layers set and ensures gorgeous, clean-cut bars that hold together beautifully.
