Ingredients and substitutions
- Apples - You'll need about 2 ½ pounds, or 5 medium apples. I recommend granny smith apples. They're available year round and add a nice tart flavor to complement the sweet crumble topping.
- Blackberries - Can be substituted with other berries like blueberries or raspberries. If using frozen blackberries, thaw them first and discard any excess juices.
- Brown sugar - Sweetens the filling and crumble topping. If your blackberries are very tart, consider adding an extra ¼ cup to the filling.
- Flour - Thickens the filling and adds structure to the crumble topping.
- Vanilla extract - Adds flavor to the filling.
- Cinnamon - Adds a warm, cozy flavor to the filling and crumble.
- Unsalted butter - Can be substituted with salted butter if desired.
How to make apple blackberry crumble
- Add apples and blackberries to a large bowl along with flour, sugar, and cinnamon. Toss until coated. Pour into a greased 7x11 baking dish.
- In a separate bowl, add crumble ingredients and stir until large clumps form.
- Sprinkle crumble topping over filling.
- Bake until apples are fork tender and crumble is browned across the top.
Tips and tricks
Adjusting the sweetness - Taste test your apples and blackberries. Are they both very tart? Early in the season, blackberries can taste more tart while later in the season they develop a sweeter flavor. To account for very tart fruits, try adding an extra ¼ cup of brown sugar to the filling or serve your crumble with a scoop of sweet vanilla ice cream.
Prefer a tart dessert?: Consider reducing the filling's sugar by ¼ cup. With your sugar reduced, that tart flavor will really shine. If your crumble turns out tart and you'd like to balance the flavor, try pairing it with a scoop of sweet vanilla ice cream.
Too sweet?: Did your crumble turn out too sweet? Try pairing it with a dollop of unsweetened homemade whipped cream. This will help balance the flavor.
Storage
Have leftover crumble? Cover the casserole dish with foil (or a lid) and store at room temperature for 2-3 days. You can also store it in the refrigerator for up to 5 days.
The crumble topping may lose its crunchy texture but will taste just as good the next day. Leftovers can be reheated in the microwave or served at room temperature.
Frequently asked questions
Granny smith apples are my go-to for baked desserts. They're widely available year round and hold their shape well in baked goods. However, granny smith apples can be a little tart, especially when paired with tart blackberries.
Honeycrisp is a great option if you'd like a sweeter crumble. You can also try using a combination of honeycrisp and granny smith for a balance of sweet and tart.
Golden delicious apples fall somewhere in the middle of sweet and tart, but will break down easily when baked. Don't reach for these if you'd like firm apple chunks in your crumble.
Crumbles and crisps can be served warm or at room temperature. I highly recommend allowing your crumble to sit at room temperature for at least 30 minutes before serving. This allows the filling to thicken and casserole to cool.
Spoon a serving of apple blackberry crumble into a bowl and serve as is, or add a scoop of vanilla ice cream or whipped cream. Ice cream is the perfect addition during those hot summer months!
