Place all crumble ingredients, except for the butter, into a food processor and pulse several times to distribute the ingredients.
Add butter cubes and pulse again until the mixture just begins to clump together. It should be around small pea sized.
Set into fridge while you mix the fruit.
For the fruit
Gently mix all ingredients except butter together in a medium bowl until the juices from the fruit have come out just enough to barely moisten all of the sugar.
Pour into prepared dish and evenly distribute chunks of butter over top.
Sprinkle crumble more or less evenly over the top of the fruit
Bake for 40 minutes or until top is browned and fruit is bubbling at the sides of the dish
Serve with ice cream or frozen yogurt
Recipe Notes
As I discovered, this crumble mix freezes very well so make extra for the next time you want to make one.
