Strawberry Rhubarb Crumble (crisp)

"This strawberry rhubarb crumble (also called a crisp!) is topped with the butteriest oat topping. Overflowing with juicy mixed fruit and a lot of crunch oat topping this crumble is baked to golden perfection and served with a few scoops of vanilla ice cream for good measure! Because we're almost as much about the topping as the fruit. Now that strawberry season is here we can skip frozen fruit and go for the juiciest strawbs and sweet-tart rhubarb. And of course, all ingredients are from Aldi."
