“A crumble with no faffing about. Can you believe it? No faff, no oven and it’s ready in 15 minutes,” says Joe Wicks.

“This speedy crumble has a few healthy shortcuts, but the end result is bang on. Tastes just as good when it hits the lips. Swap the plums for any in-season fruit and follow the same method – you may just need to lengthen the cooking times for harder fruits like apples and pears.”

You can even add any nuts, seeds or granola you like to the crumble mix, to give it a bit more crunch.
