Instructions:
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
- In a medium bowl, combine diced rhubarb with granulated sugar and 3 tablespoons of flour. Mix well and spread evenly in the prepared baking dish.
- In another bowl, mix the oats, brown sugar, and remaining 1 cup of flour. Pour in the melted butter and stir until the mixture becomes crumbly.
- Evenly sprinkle the oat topping over the rhubarb layer.
- Bake for 40 to 45 minutes, or until the topping is golden and the rhubarb is soft and bubbling.
- Remove from the oven and allow to cool slightly before serving.
Variations :
- Add berries: Mix in a cup of strawberries or raspberries for added color and flavor.
- Nutty topping: Stir in 1/2 cup chopped pecans or walnuts to the crumble for extra crunch.
- Gluten-free: Substitute a gluten-free flour blend and certified gluten-free oats to make this dessert gluten-free.
- Cinnamon spice: Add 1/2 teaspoon of cinnamon to the crumble for a warm, spiced undertone.
Tips :
- Choose rhubarb stalks that are firm and brightly colored—avoid any that are limp or greenish.
- This dessert can be prepared a few hours ahead and gently reheated in a warm oven before serving.
- For a crispier top, broil for the last 1–2 minutes of baking, but watch closely to avoid burning.
- Leftovers store well in the fridge for up to 3 days and taste great cold or reheated.
