Description
A delightful dessert bar with a buttery shortbread base, a sweet and tangy blackberry filling, and a crunchy oat crumble topping.
Ingredients
Scale
For the Crust:
- 2 cups all-purpose flour
- 1 cup rolled oats
- 1 cup granulated sugar, divided
- 1 cup (2 sticks) cold unsalted butter, cubed
- 1 large egg
- 3 cups fresh or frozen blackberries
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- 1/4 teaspoon salt
Instructions
1. Prepare the Crust:
- Preheat oven to 375°F (190°C). Grease and line a 9×9 inch baking pan with parchment paper, leaving an overhang for easy removal.
- In a large bowl, combine flour, oats, and 3/4 cup of the sugar. Cut in the cold butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs. Reserve 1 1/2 cups of this mixture for the topping.
- Mix the egg into the remaining flour mixture until a soft dough forms. Press this dough evenly into the bottom of the prepared pan to form the crust.
- In a separate bowl, gently toss the blackberries with the remaining 1/4 cup sugar, cornstarch, lemon juice, and salt until well coated. Spread the blackberry mixture evenly over the crust.
- Sprinkle the reserved crumble topping evenly over the blackberry layer.
- Bake for 35-40 minutes, or until the topping is golden brown and the fruit filling is bubbly. Allow to cool completely in the pan on a wire rack before cutting into bars.
