Ingredients
Filling
- 2 pounds rhubarb, sliced into 1-inch pieces
- ½ cup sugar
- ¼ cup flour
- 1 teaspoon vanilla extract
Crumb Topping
- 1 cup flour
- ½ cup oats
- ¾ cup brown sugar
- 6 tablespoons butter, melted
Instructions
- Preheat Oven: Preheat your oven to 375° Fahrenheit (190° Celsius) to ensure it’s hot and ready for baking your crumble.
- Prepare the Filling: In a large bowl, combine the rhubarb slices, ½ cup sugar, ¼ cup flour, and 1 teaspoon vanilla extract. Mix this mixture thoroughly to coat the rhubarb evenly and help thicken the juices during baking. Then, transfer this filling to a 9×13-inch baking dish, spreading it out evenly.
- Make the Crumb Topping: In a separate bowl, mix together 1 cup flour, ½ cup oats, and ¾ cup brown sugar. Pour in the 6 tablespoons of melted butter and stir until the mixture forms crumbly clusters. Sprinkle this crumble topping evenly over the rhubarb filling in your baking dish.
- Bake the Crumble: Place the baking dish in the oven and bake for 40-45 minutes, or until the topping is golden brown and crisp and the filling is bubbling gently along the edges. This indicates the rhubarb is cooked through and the crumble is perfectly baked.
Notes
- Use rolled oats for the best texture in the crumb topping.
- For a less tart dessert, increase sugar slightly depending on your taste preference.
- Allow the crumble to cool slightly before serving to let the filling set.
