I thought crumbles were just something fancy restaurants made until I tried making one at home. Turns out, they’re way easier than pie and honestly taste just as good—maybe better.
The best part about apple and blackberry crumble is that it’s pretty forgiving. Your fruit doesn’t need to be perfect, and the crumbly topping covers up any imperfections anyway. Plus, you don’t have to worry about rolling out pie dough or making it look pretty. Just toss everything together and let the oven do the work.
Why You’ll Love This Apple and Blackberry Crumble
- Perfect balance of sweet and tart – The combination of tender apples and juicy blackberries creates a filling that’s not too sweet, while the cinnamon adds warmth and comfort to every bite.
- Crispy, buttery topping – The crumble topping gets golden and crunchy in the oven, creating a lovely contrast to the soft fruit underneath.
- Simple ingredients you likely have – This recipe uses basic pantry staples like flour, sugar, and butter, plus seasonal fruit that’s easy to find at most grocery stores.
- Great for any occasion – Whether you’re hosting a dinner party or just want a cozy dessert for the family, this crumble works perfectly and always impresses.
- Make-ahead friendly – You can prep this crumble earlier in the day and pop it in the oven when you’re ready, making it perfect for busy weeknights or entertaining.
What Kind of Apples Should I Use?
Bramley apples are the gold standard for crumbles because they break down beautifully when baked, creating that perfect soft, fluffy texture underneath your crispy topping. If you can’t find Bramleys, other good cooking apples like Granny Smith, Honeycrisp, or even Gala will work well too. The key is choosing apples that hold their shape reasonably well but still soften during baking – you don’t want them turning to complete mush, but you also don’t want them staying rock hard. Whatever variety you choose, make sure they’re large and firm, and give them a good wash and peel before slicing.
Options for Substitutions
This crumble is pretty forgiving when it comes to swaps, so here are some easy substitutions you can make:
- Bramley apples: If you can’t find Bramley apples, Granny Smith or any tart cooking apple works great. You can even use a mix of sweet and tart apples like Honeycrisp and Braeburn for more complex flavor.
- Blackberries: Feel free to swap blackberries with blueberries, raspberries, or even frozen mixed berries. Just thaw frozen berries first and drain any excess liquid.
- Biscoff biscuits: No Biscoff? Try digestive biscuits, graham crackers, or even gingersnaps for extra spice. You can also skip them entirely and use the suggested 3 tablespoons of Demerara sugar instead.
- Demerara sugar: Light brown sugar or even regular granulated sugar works fine. Brown sugar will give you a slightly richer flavor, while white sugar keeps things simple.
- Self-rising flour: If you only have all-purpose flour, just add ½ teaspoon of baking powder per cup of flour to make your own self-rising version.
- Butter: For a dairy-free version, use cold vegan butter or even coconut oil (make sure it’s solid). The key is keeping your fat cold for the best crumble texture.
Watch Out for These Mistakes While Baking
The biggest mistake with apple crumble is cutting your apples too small, which causes them to turn to mush during baking – aim for chunky pieces about 1-inch thick so they hold their shape and provide nice texture.
Another common error is making your crumble topping too fine or overworking it, so keep your butter cold and rub it into the flour mixture just until it resembles coarse breadcrumbs with some larger chunks for the best crispy texture.
Don’t skip tossing your fruit with flour and sugar before adding the topping, as this helps thicken the natural juices and prevents a watery bottom, and make sure to bake until the crumble is golden brown and the fruit juices are bubbling around the edges.
For extra insurance against soggy bottoms, try baking your crumble on a preheated baking sheet, which gives the bottom crust a head start on crisping up.
What to Serve With Apple and Blackberry Crumble?
This warm, fruity crumble is absolutely perfect with a generous scoop of vanilla ice cream that melts right into all those sweet, juicy berries and tender apples. If you want to keep things traditional, a dollop of thick custard or heavy cream works beautifully too, especially when the crumble is still bubbling hot from the oven. For a lighter option, try some Greek yogurt or whipped cream, which adds a nice tangy contrast to the sweet cinnamon flavors. I also love serving this with a hot cup of tea or coffee – the warm spices in the crumble pair really well with both.
Storage Instructions
Keep Fresh: Your apple and blackberry crumble will stay delicious covered in the fridge for up to 4 days. I like to cover it with foil or plastic wrap to keep it from drying out. The fruit filling gets even more flavorful after a day or two, so leftovers are always a treat!
Freeze: This crumble freezes really well for up to 3 months. You can freeze it either before or after baking – just wrap it tightly in plastic wrap and foil. If freezing unbaked, add an extra 15-20 minutes to the cooking time when you’re ready to bake it from frozen.
Warm Up: To bring back that fresh-from-the-oven taste, pop individual portions in the microwave for 30-60 seconds, or warm the whole dish in a 350°F oven for about 10-15 minutes. The crumble topping gets nice and crispy again, and the fruit filling becomes perfectly warm and bubbly.

Ingredients
For the fruit mixture:
- 4 large bramley or other cooking apples
- 2 tbsp lemon juice
- 4 tbsp demerara sugar
- 2 tbsp plain flour (all-purpose)
- 1 1/2 tsp ground cinnamon
- 2 cups blackberries (wild or cultivated)
- 2 tbsp cold butter, cubed
For the crumble topping:
- 10 biscoff cookies, gently crushed (or use 3 tbsp demerara sugar as an alternative)
- 1 1/4 cups self-rising flour (or all-purpose flour plus 1/2 tsp baking powder)
- 1 cup golden caster sugar (or substitute with light brown sugar)
- 1 tsp ground cinnamon
- 1/2 cup chilled unsalted butter, cubed
Step 1: Prepare the Apple Base
- 4 large Bramley or other cooking apples
- 2 tbsp lemon juice
- 4 tbsp demerara sugar
- 2 tbsp plain flour (all-purpose)
- 1 1/2 tsp ground cinnamon
Preheat the oven to 350°F (180°C).
Peel, core, and slice the apples, then place them in a 10 ½ inch (26cm) pie dish.
Toss the sliced apples with lemon juice, demerara sugar, ground cinnamon, and plain flour until the apples are evenly coated.
This helps infuse the apples with flavor and keeps the filling from becoming too watery.
Step 2: Add the Blackberries and Bake the Fruit
- 2 cups blackberries (wild or cultivated)
- 2 tbsp cold butter, cubed
Gently fold the blackberries into the apple mixture in the pie dish so they are distributed throughout.
Dot the mixture with the cold cubed butter.
Cover the pie dish with foil or a large oven-safe lid and bake in the preheated oven for 20 minutes to soften the fruit and meld the flavors together.
Step 3: Prepare the Crumble Topping
- 10 Biscoff cookies, gently crushed (or use 3 tbsp demerara sugar as an alternative)
- 1 1/4 cups self-rising flour (or all-purpose flour plus 1/2 tsp baking powder)
- 1 cup golden caster sugar (or substitute with light brown sugar)
- 1 tsp ground cinnamon
- 1/2 cup chilled unsalted butter, cubed
While the fruit is baking, prepare the crumble topping.
If using Biscoff cookies, crush them gently in a food processor or in a bag with a rolling pin; set aside.
In a mixing bowl, combine the self-rising flour, golden caster sugar, and ground cinnamon.
Add the chilled unsalted butter and rub it into the dry ingredients with your fingertips until the mixture forms a crumbly texture that holds together in small lumps.
If the texture feels too dry, add a touch more butter; if too greasy, add a sprinkling more flour.
I like to leave a few bigger clumps in the topping for a rustic, crunchy texture.
Step 4: Top and Bake the Crumble
- crumble topping from Step 3
- crushed Biscoff cookie crumbs from Step 3
- baked fruit filling from Steps 1 and 2
Remove the partially baked fruit filling from the oven using oven mitts.
Evenly spread the crumble topping over the warm fruit, pinching sections of the topping into small clumps for texture.
Sprinkle the crushed Biscoff cookie crumbs over the top.
Return the dish to the oven and bake for another 30 minutes, or until the crumble is golden and the fruit filling bubbles up at the edges.
Step 5: Cool and Serve
Allow the crumble to cool for several minutes after baking; this helps the filling set and makes it easier to serve.
Spoon the warm fruit crumble into bowls and serve as is, or with a generous scoop of vanilla ice cream, custard, or cream.
For a touch of extra comfort, I like to serve mine with warm custard.
