🛒 Ingredients

Fruit Filling

  • 3 cups rhubarb, chopped (fresh or frozen)
  • 3 large apples (Granny Smith or Fuji), peeled and sliced
  • ½ cup granulated sugar (adjust to taste)
  • 1 tbsp lemon juice
  • 1 tbsp cornstarch
  • 1 tsp vanilla extract
  • ½ tsp cinnamon (optional)

Crumble Topping

  • 1 cup rolled oats
  • ¾ cup all-purpose flour
  • ½ cup brown sugar
  • ½ tsp cinnamon
  • ½ cup cold butter, cubed
  • Pinch of salt

👨‍🍳 Instructions

  1. Preheat oven to 180°C (350°F).
  2. Prepare filling: Mix rhubarb, apples, sugar, lemon juice, cornstarch, vanilla, and cinnamon in a bowl.
  3. Spread fruit mixture evenly in a baking dish.
  4. Make crumble topping: Combine oats, flour, brown sugar, cinnamon, and salt. Rub in butter until mixture becomes crumbly.
  5. Sprinkle crumble evenly over fruit layer.
  6. Bake for 40–45 minutes until topping is golden and fruit is bubbling.
  7. Let it cool slightly before serving.

📝 Notes

  • Rhubarb is naturally very tart; don’t skip the sugar unless you prefer a sharp flavor.
  • Apples balance rhubarb’s acidity and add natural sweetness.
  • You can use whole wheat flour for a nuttier crumble.
  • Frozen rhubarb works well—no need to thaw fully.

💡 Tips for Best Results

  • Use cold butter for a crisp, crumbly topping.
  • Add chopped nuts (walnuts or almonds) for extra crunch.
  • For deeper flavor, add a pinch of ginger or nutmeg.
  • Let it rest 10–15 minutes after baking so juices thicken.
