Step-by-Step Instructions

Step 1: Preheat Oven

Preheat your oven to 350°F (175°C) and line an 8×8 inch baking dish with parchment paper, leaving overhang for easy removal.

Step 2: Make the Crumble

In a large bowl, combine 1 ¼ cups quick oats, 1 ½ cups all-purpose flour, ½ teaspoon salt, ½ teaspoon baking powder, and ¾ cup brown sugar. Stir until well combined. Add ¾ cup melted butter and mix until a crumbly mixture forms.

Step 3: Press and Bake Crust

Press 2/3 of the crumble mixture firmly and evenly into the bottom of the prepared baking dish. Bake for 10 minutes to set the crust.

Step 4: Prepare the Berry Filling

In another large bowl, combine 1 cup fresh raspberries, 1 cup fresh blackberries, and ⅓ cup brown sugar. Gently mash the berries once with a fork. Stir in 3 tablespoons cornstarch, 2 tablespoons lemon juice, 1 teaspoon vanilla extract, 2 teaspoons lemon zest, and ¼ cup strawberry preserves until well combined.

Step 5: Assemble the Bars

Pour the berry mixture over the baked crust and spread evenly. Sprinkle the remaining crumble mixture on top.

Step 6: Bake

Bake for 35–40 minutes, or until the top is golden brown and the filling is bubbly.

Step 7: Cool and Serve

Allow bars to cool completely before slicing. Use the parchment overhang to lift the bars from the dish. Slice into 8 servings and enjoy.
