Preheat oven to 350 °F (175 °C).

Toss berries with lemon juice, sugar (or maple syrup), and vanilla. Spread in a greased 8×8″ baking dish.

In a bowl, combine oats, flour, brown sugar, cinnamon, and salt.

Add cold butter and use fingers or a pastry cutter to form pea-sized crumbs.

Sprinkle crumble evenly over berries.

Bake uncovered for 40–50 minutes, until bubbling and golden.

Let rest 10 minutes before serving.

Add nuts like pecans or walnuts to the topping for crunch.

Use maple syrup for a richer sweetness or toss berries with cornstarch to reduce runniness.

Serve warm with ice cream or chilled with yogurt.
