A quick and simple rhubarb crumble recipe designed for single servings, perfect for dorm rooms or small kitchens. This dessert balances tart rhubarb with a crunchy oat topping and can be made with minimal equipment.
Keep butter cold for a crumbly topping. If topping browns too quickly, cover loosely with foil halfway through baking. For a softer topping, microwave for 2-3 minutes. Uniform rhubarb pieces cook more evenly. Leftovers keep up to 2 days refrigerated and can be frozen before baking for up to a month.
