Apple Rhubarb Crumble Ingredients
For the Fruit Filling
• 3.5 cups rhubarb – Fresh rhubarb adds a vibrant tartness that perfectly balances the sweetness of the apples. If using frozen, defrost and drain the liquid before measuring.
• 2 cups apples (peeled and diced) – Choose Fuji or Granny Smith apples for their sweet and tart flavors, enhancing the fruit filling beautifully.
• 3/4 – 1 cup sugar – A key ingredient that sweetens the mixture; opt for 1 cup for a sweeter dessert experience.

Step‑by‑Step Instructions for Apple Rhubarb Crumble
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C) and greasing an 8×8 baking pan with non-stick spray. This ensures that your delicious Apple Rhubarb Crumble won’t stick during baking, allowing for easy lifting and serving. While the oven warms, gather your ingredients to streamline the process and make your cooking experience pleasant.
Step 2: Mix the Fruit Filling
In a large mixing bowl, combine 3.5 cups of chopped rhubarb, 2 cups of peeled and diced apples, and 3/4 to 1 cup of sugar. Sprinkle 4 tablespoons of cornstarch over the mixture to thicken the filling. Use a gentle folding motion to coat the fruit evenly. Once well mixed, pour this enticing fruit mixture into your prepared baking pan, spreading it evenly across the bottom.
Step 3: Prepare the Crumble Topping
In another bowl, blend 1 cup of old-fashioned oats, 1/2 cup of melted butter, 1/3 cup of all-purpose flour, 1 teaspoon of cinnamon, and 1/2 cup of brown sugar. Stir the mixture until it comes together into a crumbly topping. Make sure not to over-mix; you want to maintain a hearty texture. This delightful topping will provide a crunchy contrast to the soft, warm fruit below.
Step 4: Assemble the Crumble
Once your toppings are mixed, even sprinkle the crumble mixture over the fruit layer in the pan. Spread it out gently, ensuring even coverage, which will help create a uniformly golden topping. This step is crucial, as it means each bite of the Apple Rhubarb Crumble will delight with its crispy texture and sweet fruit underneath.
Step 5: Bake to Perfection
Place the assembled crumble in your preheated oven and bake for 40 to 45 minutes. Look for the topping to turn a lovely, golden brown and the fruit to bubble up around the edges. The aroma of sweet and tart rhubarb mingling with the crunchy topping will fill your kitchen, creating anticipation for this comforting dessert.
Step 6: Cool and Serve
After baking, remove the Apple Rhubarb Crumble from the oven and allow it to cool for about 15 minutes. This resting time is important as it allows the juices to set, making it easier to slice and serve. Enjoy your warm crumble alone or add a scoop of vanilla ice cream on top for a delightful finish!
Storage Tips for Apple Rhubarb Crumble
Room Temperature: Keep the crumble covered at room temperature for up to 2 days if you plan to eat it quickly.
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days to maintain freshness and flavor.
Freezer: For long-term storage, freeze the completely cooled Apple Rhubarb Crumble in a freezer-safe container, where it will last for up to 3 months.
Reheating: Reheat slices in the microwave for a quick treat or warm the whole crumble in the oven at 350°F (175°C) for about 15-20 minutes until heated through.
Make Ahead Options
These Apple Rhubarb Crumble with Oats are perfect for busy home cooks looking to save time! You can prepare the fruit filling by mixing the rhubarb, apples, sugar, and cornstarch up to 24 hours in advance; simply cover it and refrigerate until you’re ready to bake. The crumble topping can also be made ahead, storing it in an airtight container at room temperature for up to 3 days. To maintain quality, keep the topping separate until you’re ready to assemble and bake. When you’re ready to enjoy your dessert, layer the unbaked fruit and topping in your pan, and bake as instructed for a cozy, comforting treat that tastes just as delicious as when freshly made!
