Ingredients
For the Rhubarb Filling
- 6 cups fresh rhubarb, chopped into ½-inch pieces
- 1 cup granulated sugar
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
For the Oat Crumble Topping
- 1 cup old-fashioned rolled oats
- 1 cup all-purpose flour
- ¾ cup brown sugar
- 1 teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup cold unsalted butter, cubed
Instructions
Step 1: Preheat Oven
Preheat oven to 375°F (190°C).
Lightly grease an 8×8-inch baking dish.
Step 2: Prepare the Rhubarb Filling
In a large bowl combine:
- Chopped rhubarb
- Granulated sugar
- Cornstarch
- Lemon juice
- Vanilla extract
Mix thoroughly until the rhubarb is evenly coated.
Step 3: Fill the Baking Dish
Transfer the rhubarb mixture into the prepared baking dish.
Spread evenly.
Step 4: Make the Oat Crumble
In a medium bowl combine:
- Rolled oats
- Flour
- Brown sugar
- Cinnamon
- Salt
Add cold butter cubes.
Using a pastry cutter, fork, or your fingertips, work the butter into the mixture until crumbly.
Step 5: Add the Topping
Sprinkle the crumble mixture evenly over the rhubarb filling.
Cover the entire surface.
Step 6: Bake
Bake for 40-45 minutes.
The topping should become golden brown and the filling should be bubbling around the edges.
Step 7: Cool Slightly
Remove from oven and allow to cool for about 10-15 minutes before serving.
This helps the filling thicken.
Notes
Use fresh or frozen rhubarb; if using frozen, thaw and drain excess liquid first.
Bake until the oat crumble topping is golden brown and the rhubarb filling is bubbling.
Serve warm with vanilla ice cream or whipped cream for the best flavor and texture.
