- For the Crisp Topping & Base:
- 1-¼ cups all-purpose flour
- 1 cup old-fashioned oatmeal
- 1-¼ cups light brown sugar, packed
- ½ cup unsalted butter, melted
- 1 teaspoon ground cinnamon
- For the Rhubarb Filling:

- For the Sugar Sauce:

Notes & Substitutions
For the best results with your Easy Rhubarb Crisp, consider these helpful tips. Use fresh, vibrant rhubarb or ensure your frozen rhubarb is thoroughly thawed and drained to prevent excess moisture. Old-fashioned oats provide the best chewy texture for the crisp topping, but quick oats can be used for a slightly softer finish. If you prefer a richer, deeper molasses flavor, dark brown sugar makes an excellent substitute for light brown sugar. Margarine or solid, then melted, coconut oil can replace butter if needed.
Understanding the properties of cornstarch is key to achieving a perfectly thickened fruit filling. Bob’s Red Mill provides an excellent guide on the role of cornstarch in baking, explaining how it works as a thickening agent.
Finally, arrowroot powder works as a fantastic alternative if you do not have cornstarch for the sauce.
🧑🍳 Equipment
You only need a few basic kitchen tools to make this delightful Easy Rhubarb Crisp.
- 9×13 inch baking dish (or 7×11 inch, 8.5×11 inch as per instructions)
- Large mixing bowls for combining ingredients
- Small microwave-safe bowl for the sauce

👨🍳 How to Make Easy Rhubarb Crisp
Crafting this Easy Rhubarb Crisp is a straightforward and enjoyable process. Follow these simple steps for a perfect outcome.
First, preheat your oven to 350°F (175°C). Lightly grease a 7-inch x 11-inch or 8.5-inch x 11-inch baking dish with butter or cooking spray, then set it aside. This prepares your dish for baking.
Next, prepare your crisp topping and base. In a large mixing bowl, combine the all-purpose flour, old-fashioned oats, ground cinnamon, and packed light brown sugar. Pour in the melted unsalted butter and mix well. Stir everything together with a fork or your fingers until the mixture is crumbly and well combined.
Now, form the base of your crisp. Press exactly half of this delightful crumb mixture evenly into the bottom of your prepared baking dish. This creates a sturdy foundation for the rhubarb.
Evenly spread all the chopped rhubarb over the pressed-in crumb mixture in the baking dish. Ensure a single layer so it cooks uniformly.
In a small, microwave-safe glass bowl, whisk together the granulated sugar, cornstarch, and cold water until smooth. Microwave this mixture for approximately 3-5 minutes, stirring halfway through, until it becomes thick, clear, and bubbly. This creates a glossy, flavorful sauce. Remove the bowl from the microwave and stir in the vanilla extract.
Carefully pour the warm sugar sauce evenly over the chopped rhubarb in the baking dish. Make sure every piece of rhubarb is coated for optimal flavor and moisture.
Finally, sprinkle the remaining half of the crumb mixture evenly over the top of the sauced rhubarb. This will form the signature crispy topping.
Bake your Easy Rhubarb Crisp in the preheated oven for about 30-40 minutes. Look for the edges to be bubbling gently and the crumb topping to be beautifully golden brown.
Once baked, remove the crisp from the oven and let it cool slightly on a wire rack before serving. This allows the filling to set and prevents it from being too runny.
🔥 Pro Tips & Troubleshooting
Achieve the perfect Easy Rhubarb Crisp every time with these valuable pro tips. Always use fresh, firm rhubarb stalks for the best flavor and texture. If using frozen rhubarb, ensure you thoroughly thaw and drain it to prevent a watery filling. When making the crisp topping, avoid overmixing; gently combine ingredients until just crumbly for the ideal texture. Feel free to adjust the sugar level in the sauce based on the tartness of your rhubarb and your personal preference. Cooling the crisp properly is essential for the filling to set and achieve the best consistency. If you notice the topping browning too quickly during baking, simply cover the dish loosely with aluminum foil. Always bake until the edges are visibly bubbling and the topping has turned a rich, golden brown for a fully cooked and delicious dessert.
