Apple Rhubarb Crumble Ingredients
For the Fruit Filling

For the Crumble Topping
• Old-Fashioned Oats – 1 cup; don’t swap for quick oats to keep that beloved crunch.
• Butter – 1/2 cup, melted; use either salted for flavor or unsalted based on preference.
• All-Purpose Flour – 1/3 cup; provides structure; opt for gluten-free flour if necessary.
• Cinnamon – 1 teaspoon; enhances aroma and flavor; adjust based on your taste.
• Brown Sugar – 1/2 cup; adds moisture and depth; a must for that comforting crumble topping.
Step‑by‑Step Instructions for Apple Rhubarb Crumble
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grab an 8×8-inch baking pan and lightly grease it with non-stick spray. This will ensure that your delectable Apple Rhubarb Crumble comes out easily once baked, providing a perfect foundation for the juicy fruit filling and crunchy topping.
Step 2: Prepare the Fruit Filling
In a large mixing bowl, combine 3.5 cups of diced rhubarb, 2 cups of peeled and diced apples, and 3/4 to 1 cup of sugar. Sprinkle in 4 tablespoons of cornstarch, gently tossing everything until the fruits are well coated. The mixture should glisten slightly from the sugar, indicating that it’s ready to be layered in the prepared baking pan.
Step 3: Layer the Fruit Mixture
Carefully pour the rhubarb and apple mixture into the greased baking pan, spreading it evenly across the bottom. As you do this, take a moment to admire the vibrant colors of the fruit—this beautiful foundation will create a delightful contrast with the crisp topping. Set the pan aside while you prepare the crumble.
Step 4: Make the Crumble Topping
In another mixing bowl, mix together 1 cup of old-fashioned oats, 1/2 cup of melted butter, 1/3 cup of all-purpose flour, 1/2 cup of brown sugar, and 1 teaspoon of cinnamon. Stir until the mixture resembles coarse crumbs, with the oats and sugar evenly distributed. The aroma of cinnamon filling the air should excite your senses as you prepare for the final layer of the Apple Rhubarb Crumble.
Step 5: Spread the Topping Evenly
Once the topping is ready, spread it evenly over the fruit mixture in the baking pan. Use your fingers or a spatula to gently push the crumble mixture into place, ensuring that every bit of fruit is covered. This will create that signature crunchy texture, inviting everyone to dig in once the crumble is baked to perfection.
Step 6: Bake to Perfection
Transfer the assembled Apple Rhubarb Crumble to the preheated oven and bake for 40-45 minutes. Keep an eye out for a golden-brown topping and bubbling fruit peeking out at the edges. When finished, the topping should be crisp, and the filling should be tender, inviting you to savor each warm, delicious bite.
Step 7: Cool and Serve
After removing the crumble from the oven, allow it to cool for at least 15 minutes before serving. This cooling time will help the filling set a bit more, making it easier to scoop. As you prepare to treat yourself or your loved ones, take a moment to savor the comforting aroma wafting through your kitchen, promising a delightful experience ahead.

Apple Rhubarb Crumble Recipe FAQs
How do I select the best rhubarb for my crumble?
Absolutely! When selecting rhubarb, look for firm, crisp stalks that are a vibrant pink or green. Avoid any that have dark spots or are limp, as this indicates they may be past their prime. Fresh rhubarb typically has a slightly tart smell, which is a good sign of freshness.
What’s the best way to store leftover Apple Rhubarb Crumble?
To store your Apple Rhubarb Crumble, transfer it to an airtight container and keep it in the refrigerator for up to 3 days. This will help maintain its delightful flavors and crunchy topping. If you plan to enjoy it later, consider separating the topping from the filling to keep that wonderful crunch intact!
Can I freeze my Apple Rhubarb Crumble?
Yes, you can! To freeze your crumble, ensure it has cooled completely after baking. Wrap it tightly in plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. It can be safely stored for up to 3 months. When you’re ready to enjoy, thaw it overnight in the refrigerator and reheat it in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through.
How do I fix a runny filling in my crumble?
If you find your filling is too runny, there are a couple of troubleshooting tips you can use. First, let the crumble cool longer before serving as the filling will thicken more as it cools. If you’ve baked it and it’s still runny, you can thicken it on the stovetop by simmering the mixture on low heat with a little cornstarch mixed with water until thickened. Another tip is to ensure you’ve used enough cornstarch to bind the juices during the initial mixing.
Are there any allergy considerations I should keep in mind?
Very! If you’re serving this Apple Rhubarb Crumble to guests, consider potential allergens like gluten and dairy. To make it gluten-free, substitute arrowroot flour for all-purpose flour and use certified gluten-free oats. For a dairy-free topping, consider using coconut oil instead of butter. It’s always great to check with your guests, ensuring everyone can enjoy this tasty dessert!
