Blackberry Crumble

Step 1:

Preheat your oven to 180°C (350°F).

Step 2:

In a large mixing bowl, combine the frozen blackberries, granulated sugar, cornstarch, lemon juice, and vanilla extract. Mix well to coat the blackberries evenly.

Transfer the blackberry mixture to a greased baking dish.

Step 3:

In another bowl, combine the rolled oats, flour, brown sugar, cinnamon, and salt.

Add the cold butter pieces to the mixture. Using your fingers or a pastry cutter, mix until the mixture resembles coarse crumbs.

Step 4:

Sprinkle the crumble topping evenly over the blackberry filling.

Step 5:

Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the filling is bubbly.

Step 6:

Let the blackberry crumble cool for at least 15 minutes before serving.

Step 7:

Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.
