I look forward to rhubarb season every spring. There’s just something about tart rhubarb that begs to be made into dessert!
This Old Fashioned Rhubarb Crumble strikes the perfect balance between sweet and tart. It’s simple to make, it requires basic pantry/refrigerator staples, and it’s absolutely delightful served warm with a scoop of vanilla ice cream on top.

Ingredients

- You’ll need 3–4 large stalks of fresh rhubarb for this recipe. Late April/early May is when I start to see it at grocery stores in Chicago. If I’m the lucky recipient of home-grown rhubarb from friends, I’ll usually make some rhubarb sauce with any extra!
- Be sure to use unsalted butter here. If it’s salted, omit the salt. The tartness of the rhubarb doesn’t pair well with too much salt.
How to Make Old Fashioned Rhubarb Crumble
- Toss the rhubarb with the flour, white sugar, egg, and baking powder.
- Transfer to a greased baking dish.
- Cut the butter into the brown sugar, flour, and salt until it’s crumbly. You can use a pastry blender, two forks, or your hands for this.
- Pour over the rhubarb mixture, and bake for 30–35 minutes, or until golden brown on top.
