These bars combine tangy rhubarb and sweet strawberries with a buttery, crumbly oat topping for a perfect summer snack that’s quick and easy to make.
Use cold butter for the crumble topping to ensure a flaky, golden crunch. Let bars cool completely before slicing for clean cuts. If edges brown too quickly, tent with foil. Frozen berries can be used if thawed and drained well. For gluten-free, substitute flour and oats accordingly. For dairy-free, use coconut oil instead of butter.
