Ingredients
- 2 cups fresh blackberries

- 1 cup rolled oats
- 1/2 cup brown sugar
- 1/2 cup granulated sugar
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, melted
- 1 teaspoon vanilla extract
- 1 teaspoon lemon juice
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and line a baking pan (approximately 8×8 inches) with parchment paper, letting some hang over the sides for easy removal later.
- Prepare the filling: In a bowl, combine the blackberries, lemon juice, and one tablespoon of granulated sugar. Set aside while you prepare the crust.
- Make the crust: In a separate bowl, mix the all-purpose flour, rolled oats, brown sugar, granulated sugar, and salt. Stir in the melted butter and vanilla extract. The mixture should resemble wet sand.
- Layer the crumble: Take about two-thirds of the crumble mixture and press it evenly into the bottom of your prepared pan.
- Spread the filling: Evenly distribute the blackberry mixture over the crust.
- Top with remaining crumble: Sprinkle the remaining crumble over the berries, covering them completely.
- Bake for about 30-35 minutes, until the top is golden brown and the filling is bubbly.
- Cool: Allow the bars to cool for at least 20 minutes before using the parchment to lift them out of the pan. Cut into squares.
Top Tips for Perfecting Blackberry Crumble Bars
- Substitutions: If you don’t have fresh blackberries, consider using frozen ones or swapping them for other fruits like blueberries or raspberries—keep it halal-friendly!
- Timing: Keep an eye on the bars as they approach the 30-minute mark to avoid over-baking; you want that golden color for the perfect texture.
- Avoid mistakes: Be sure to layer the filling evenly for consistent flavor in each bite, and don’t skip letting them cool—this helps them set!
