Ingredients
Ingredients:
– 5 cups rhubarb (frozen or fresh, chopped (about 600g))
– 3/4 cup granulated sugar (150g)
– 1/4 cup corn starch
– 1/2 cup butter (cold, cubed)
– 1/2 cup brown sugar (lightly packed)
– 1 1/2 cups rolled oats
– 1/2 cup whole wheat flour (or substitute all-purpose) (65 g)
How to Make Rhubarb Crisp
Step 1: Preheat the Oven
Preheat your oven to 375 degrees F. Grease an 8×8 or 9×9-inch baking pan lightly to prevent sticking.
Step 2: Prepare the Rhubarb Filling
In a large bowl, combine the chopped rhubarb, granulated sugar, and corn starch. If you are using fresh rhubarb, reduce the corn starch to only 2 tablespoons. Pour this mixture into the prepared pan evenly.
Step 3: Make the Crumble Topping
In another large bowl, mix together the butter, brown sugar, rolled oats, and whole wheat flour. You can use a pastry cutter, fork, or your hands to combine until crumbly. Spread this topping over the rhubarb filling in the pan and press down lightly.
Step 4: Bake
Place your pan in the preheated oven and bake for about 35–40 minutes. Look for a golden-brown top with thick, bubbly edges. After baking, let it sit for about 10 minutes before serving it warm with ice cream. Enjoy!

Common Mistakes to Avoid
Making a Rhubarb Crisp is simple, but there are common mistakes that can affect your dish. Here are some pitfalls to avoid.
- Using too much corn starch – Adding excessive corn starch can make your filling overly thick. Stick to the recommended amount for the best texture.
- Not measuring rhubarb correctly – Using more or less than 5 cups of rhubarb can alter the balance of flavors. Always measure carefully!
- Skipping the chilling of butter – If you use warm butter, your topping will not be as crumbly and delicious. Always use cold, cubed butter for the oat topping.
- Overbaking or underbaking – Baking for too long can burn the topping, while not baking long enough leaves it soggy. Keep an eye on your crisp and look for a golden brown color.
- Forgetting to let it cool – Serving immediately without letting it sit can cause the filling to run. Allowing it to cool for about 10 minutes helps set the filling.
