Step 1

Preheat the oven to 350°Fahrenheit. Grease an 8- or 9-inch baking dish with butter.

Step 2

In a medium bowl, toss the halved strawberries with the sugar, cornstarch, lemon juice, lemon zest, and vanilla extract until evenly coated. Spread the strawberry mixture evenly into the bottom of the prepared baking dish.

Step 3

In a separate mixing bowl, whisk the flour, baking powder, granulated sugar, and salt. Add the cold cubed butter and use a pastry cutter or your fingers to combine until the mixture resembles coarse crumbs.

Step 4

Sprinkle the crumble mixture evenly over the strawberry filling, ensuring the top is fully covered.

Step 5

Bake for 35-40 minutes until the topping is golden brown and the strawberry filling is bubbling. Let the crumble cool for 10-15 minutes before serving.

Step 6

Serve warm with vanilla ice cream or whipped cream. Enjoy!
