This classic style of rhubarb crumble is easy to make and especially delicious served warm with cream or vanilla ice cream.

Ingredients & Substitutions

Rhubarb: Gives the crumble its tart, fruity base. Fresh rhubarb works best, but frozen rhubarb can be used if thawed and drained.
Sugar: Sweetens the rhubarb and balances its sharpness. You can reduce the amount slightly if your rhubarb is naturally mild.
Cornstarch: Helps thicken the rhubarb juices so the filling is not watery.
Butter: Adds richness and helps create the crumbly topping. Cold butter gives the best texture.
Flour: Helps bind the crumble mixture together.
Oats: Add a hearty texture and extra crunch. Rolled oats are best.
Brown sugar: Brings a deeper caramel-like sweetness to the topping.
Cinnamon: Adds warmth and a cozy flavor.
Powdered sugar: Optional, for dusting the top before serving.
Vanilla ice cream or cream: Optional for serving.

Tips for Success

Use cold butter so the topping bakes up crumbly instead of pasty.
Cut the rhubarb evenly to help it cook at the same rate.
Do not overmix the topping; it should stay sandy and crumbly.
Bake until the filling bubbles so you know the rhubarb has softened and thickened.
Let it rest before serving so the juices settle a little.
Serve warm for the best flavor and texture.
