These easy tangy strawberry rhubarb crumble bars combine a buttery crumble base with a juicy, tangy fruit filling, perfect for a refreshing summer snack or casual dessert.
Keep butter cold until mixing to ensure a crumbly texture. Bake crust before adding filling to prevent sogginess. Use cornstarch to thicken filling. Cool bars completely before slicing to help them hold together. Tent with foil if topping browns too quickly. Frozen fruit can be used if thawed and drained. For gluten-free, substitute flour with gluten-free blend; for dairy-free, use coconut oil instead of butter.
