This old fashioned rhubarb crisp recipe features a lovely sweet and tart rhubarb filling under a brown sugar and oat topping. It is such a wonderful way to highlight spring's strangest (and tastiest) vegetable.
Preheat your oven to 350℉ and grease an 8-inch baking dish.
Put rhubarb in a layer on the bottom of the prepared pan.
In a small saucepan, mix together the sugar and cornstarch. Add the water. Cook over medium heat until it starts to boil and thicken. Distribute over the rhubarb.
In a small bowl, stir together the brown sugar, flour, oats, and cinnamon.
Add the melted butter and combine until mostly uniform. Sprinkle over rhubarb.
Bake for 55-60 minutes or until the rhubarb layer is bubbly and the oat topping is browned.
Notes
You can use all-purpose flour in place of the whole wheat flour if you prefer.
