A simple, tangy rhubarb crisp with a sweet, crumbly oat topping that balances tartness and sweetness, perfect for summer desserts.
Use cold butter for a crumbly topping. If topping browns too quickly, cover loosely with foil for the last 10 minutes. Adjust sugar to taste depending on rhubarb tartness. Flour thickens the filling; add cornstarch for extra thickness if desired. The crisp is delicious warm or chilled and reheats well. For gluten-free, substitute almond flour and certified gluten-free oats. For dairy-free, use coconut oil or vegan butter.
