For a nutty twist, add a handful of chopped walnuts or pecans to the crumble topping. If you prefer a spicier cake, increase the cinnamon to 1 1/2 teaspoons and add a pinch of nutmeg.

To make this recipe dairy-free, use a plant-based milk and substitute the butter with coconut oil or a dairy-free butter alternative.
