Easy Blackberry Crumble
Desserts like this blackberry crumble make summer more fun. It only takes a few minutes to bake, and you get deliciously soft, sweet yet tart berries with crisp crumble. Serve it with a scoop of ice cream for that ultimate luxury.

We have lost count of how many fruit crumbles and clafoutis I have made this summer. My kids have really been enjoying it so much. Not just eating, but helping in making them too!
Why make this blackberry crumble?
- One of the reasons I love berry crumbles is this. Look at that thick tart yet sweet chewy fruit syrup. Next, look at the crisp buttery bits of crumble on the top. Now imagine a spoonful of that syrupy fruit with the crispy crumble that just bursts in the mouth. There’s a mouthful you cannot resist. Explosion!
- A fruit crumble is really the easiest dessert you can make in summer with any fruit. Berries and stone fruit such as peaches, apricots, and apples are always a big hit.
- Today, I am making these with blackberries. But, you can also make them with other berries such as raspberries, blueberries, or even a combination of mixed berries. Of course, stone fruits such as apricot, plums, peaches, and nectarines, are also the perfect candidates for crumbles.
- By the way, crumble bars are a great way to take these fruit crumbles to family and friends when you visit.

Ingredients and substitutes
- Blackberries – Today, I am using fresh, and yet you can also use frozen. And if you use frozen, you can keep the amount of sugar the same. I’d love to say you can also use canned, and yet with canned, I find the fruit is too soft and becomes syrupy by the time it’s cooked. It still tastes good, but the fruit is almost down to a syrup consistency.
- Sugar – I like using a mix of white and brown sugar. The white adds sweetness and keeps a beautiful white color, while the light or brown sugar brings with it the flavor of molasses, which when combined with cinnamon or nutmeg is an absolute luxury.
- Unsalted Butter – I always use unsalted because I like to control the amount of salt I use. And if you use salted butter, that’s fine. Just omit salt in the recipe. Margarine or veg shortening works as well, and yet they both will affect the texture of the crumble. Since margarine has a bit more liquid, you may need to use a tad less. While vegetable shorting will make the crumble topping crisper.
- Cornstarch – Blackberries are juicy, and the cornstarch helps thicken the juices giving you that thick syrup-like consistency instead of a pool of liquid.
- Vanilla – Always use good quality vanilla extract, bean paste, or vanilla sugar.
- Spice mix – There are so many flavors you can add. Like pumpkin spice or gingerbread spice, cinnamon, and nutmeg. I admit that when it comes to crumble, I often prefer the fruit to shine. So, I usually add just a pinch of cinnamon and a grating of nutmeg.

Blackberry crumble
- Preheat the oven to 375°F / 190°C/ Gas Mark 5.
- Crumble – In the bowl of a food processor, add the flour, nuts/oats, sugars, salt, vanilla extract, spice, and chilled cubed butter. Pulse a few times – until you combine small and large breadcrumb consistency. Keep chilled.
Pro tip – The crumble mixture can be made up to 4 days in advance. Keep it in the fridge to ensure the butter stays chilled.

- Fruit – Combine the blackberries, sugars, lemon juice, salt, and cornstarch in a greased 8 x 8 square pan or 6-inch pie pan. Alternatively, you can use 4 x 4 oz ramekins for individual servings. Set aside.
Pro tip – Greasing the pan with butter is optional, but it also adds a nice flavor. - Sprinkle the crumble mixture on top of the blackberries. Make sure to cover all areas.
Pro tip – I like to do this with my hands and make sure to cover all areas. Try to put the large crumble pieces on the top as they do look prettier.

- Bake for about 20 to 25 minutes or until the top is crisp and golden. Let cool for 10 minutes before you serve.
Pro tip – If you choose to make small individual ramekins, you will need only 12 to 15 minutes of baking time. - Fruit crumble can be served hot or cold. We love to serve it warm with chilled ice cream or cold with whipped cream.
Pro tip – The fruit syrup is very hot so make sure to wait for 10 minutes to prevent anyone from getting hurt.

Tips for success
- Fruit – you can use fresh or frozen blackberries. If using frozen make sure to thaw well, then drain excess moisture so the crumble does not become soupy.
- The perfect crumble topping is in the ratio of flour, sugar, and butter – Two parts flour, one part butter, and one part sugar works every single time. You can replace some of the flour with oats and nuts.
- Freezing crumble mixture – you can store any extra crumble mix well wrapped in a freezer bag (to prevent ice crystal) for up to 3 months.
- Gluten-free fruit crumbles – simply replace the flour in the recipe with your favorite-gluten free flour and oats.
- Reducing sugar – you can reduce sugar by simply tasting the blueberries. If you have sweet blueberries reduce the sugar accordingly. If the blueberries are tart, you can also use maple syrup or honey to substitute some of the sugar.
- Reheating crumble -A few minutes in the microwave will bring it back to it syrupy goodness. Then a few minutes in the oven will help crisp the streusel topping as well.

Frequently asked questions
I love baking the crumble fresh, so the topping stays wonderfully crisp. And yet, you can make this crumble in advance. Cool it completely before you wrap it well and place it in the fridge.
Both are baked fruit desserts. A cobbler uses dollops of biscuit dough or pie dough topping, which often when baked looks very similar to a cobblestone. A crumble uses a streusel-like topping made of flour, sugar, and butter with the addition of nuts.
Again a crumble and a crisp are also both baked fruit desserts and both use a streusel topping made with butter, sugar, and flour. And yet, a crumble uses the addition of nuts while crips use rolled oats. These oats become crisp and flaky when cooked while the crumble topping is cakey and dense.
It is very tempting to add more butter to the crumble topping, but too much butter will blend the mixture of flour and sugar. Creating the perfect crumb with flour and sugar requires that you do not add too much butter. Ideally, a ratio of 1:1:2 works best – One part butter: one part sugar: two parts flour

Tried to follow this recipe with a family member. We were lost on the first step. The ingredient lists were utterly unorganized making the recipe nearly impossible to follow. We started combining ingredients in our food processor and when the oats, flour and sugars were inside and it said to add salt we became confused because there was no salt listed in the crumble section. When inspecting the recipe further to figure it out, we found that the fruit mixture ingredients were the same way, with lots of extra ingredients that would seemingly not be used. Not sure how this recipe is rated one of the best blackberry crumble recipes on the internet when it is completely not usable. Wasted lots of ingredients on trying this. Maybe instead of including “pro tips” the focus could be on making the recipe easier to follow. Looks great in the pictures but just wish we could recreate this in real life
Hey Ella, This is a simple, easy, and straightforward recipe.
The ingredients are divided into two sections.
Combine the first section (fruit) directly in the baking pan.
Then, you add all the second section (crumble ingredients) to a food processor and blend.
Pour the crumble over the fruit and bake!!
I have also added the ingredients at each step so you don’t miss out.
I hope you find that useful too.
Thanks for the feedback.
I’m going to use blackberries but really confused by the pictures and instruction about blueberries
Hey Ash, the pictures for my blackberries didn’t turn out so I had to use the blueberries – but everything is exactly the same as shown step by step
No one has left a comment about their results with this recipe so I would like to. All I can say is WOW! Perfect sweetness, tartness and the crumble was just what I love. The ease of the recipe I loved also. I have tried so many before and always comes out runny and too sweet. I did use fresh blackberries and no oats in crumble (just not a fan of oats). But everything else was according to recipe. Thank you thank you!
Thank you so much, Lisa. It is nice to get feedback from people who have tried the recipe. Happy you enjoyed this recipe.
Yum! Love this recipe! So perfect for summer dessert!
Thanks Kim.
This looks like the perfect summer dessert!
Thanks, Amy
