How do I know when my crumble is done?

Chef's answer
Bake in the preheated oven for about 45 minutes. The apple layer should be bubbling and the surface of the crumble should be an even medium golden brown. If you are using a shallower, slightly larger baking pan like a 9x9, watch it closely, the crumble may be done in 5 or 10 minutes less time.
