Making fruit crumbles is the easiest way to use up summer fruit especially if you love to pick it yourself. Because you will end up with a lot of it! Blackberries are some of the easiest fruits to find as they simply grow everywhere. They are sweeter than store-bought and don’t cost a penny. So it’s easy to get carried away and pick a little too many.

But that’s not necessary a bad thing since blackberries are incredibly nutritious, packed with fibre, vitamins and delicious flavour. Perfect to enjoy in a breakfast crumble.

Blackberry crumble ingredients

The filling consists of blackberries, 2 tablespoons of light brown sugar and 1 tablespoon of cornstarch.

For the crumble topping I chose a mixture of old-fashioned oats, whole wheat flour, nutritious flaxseed, a small amount of light brown sugar, cinnamon for more flavour and butter to keep it all together and create a crispy crumble.

Do I have to make the crumble topping in the food processor

No, you don’t. You can mix all the topping ingredients by hand using your fingertips to rub the ingredients together until crumbly. The drawback of not using a food processor is that it takes longer to ensure all the ingredients have been thoroughly incorporated and the flour is no longer visible.

Top tips and FAQs

Make ahead: you can prepare the crumble in advance, refrigerate overnight and bake the next day.
When making the crumble topping (whether in the food processor or by hand) mix the ingredients thoroughly until the dry ingredients are no longer visible.

Substitutions

Light brown sugar: I used this sugar for its delicious caramel flavour but demerara, muscovado or coconut sugar would work well too.
Flaxseed: Use crushed nuts, almond flakes, chia seeds or sunflower seeds instead.
Oats: While I do not recommend using instant oats, barley as well as rye oats are good alternatives to old-fashioned oats.
Butter: If you would like to enjoy this blackberry crumble vegan use coconut oil instead (refrigerate it beforehand to ensure it’s set, not runny).
Cinnamon: You could use pumpkin spice or ground ginger instead or simply omit the spice.

Serving suggestions

If you are serving this crumble as a breakfast dish enjoy it with low fat yogurt (plain or flavoured) or add a dollop of ricotta cheese. For a dessert idea enjoy with a scoop of vanilla ice cream or topped with whipped cream.

What else can you do with blackberries

Another easy recipe idea is turning your blackberries into either a blackberry sauce or fruit compote. You can either use blackberries on their own or combine them with other berries. You can also make a delicious blackberry coffee cake with a crumble topping, perfect to enjoy with a cup of tea or coffee.

One idea that takes me back to my childhood is eating freshly picked blackberries with a couple of spoonfuls of sour cream and a little sugar. It’s simple, delicious and perfect as a snack or summer dessert.
