Easy Blackberry Crumble Summer Treat
We have lost count of how many fruit crumbles I have made this summer such as peach and raspberry crumble, blueberry crumble, apricot crumble squares. My kids have really been enjoying it so much. Not just eating but making the crumble too! My Rhea loves the job of squishing the butter sugar and flour so often she will choose to make crumble for desserts. Considering we love summer fruit so much it’s been a real big treat this summer.
Another great way to use summer berries is in a classic fresh Clafoutis which is custard based like my blackberry tart or my plum Clafoutis. I could go on and on about my indulgence with summer fruits into desserts but I’ll share more on that at the bottom of this post.

Easy Blackberry Crumble Summer Fruit Desserts
Let’s talk Ingredients and Substitutes
- Blackberries – Today I am using fresh but you can use frozen too. If using frozen you can keep the amount of sugar the same. I’d love to say you can use canned but with the canned I find the fruit is to soft and really become syrupy by the time it’s cooked. It still taste good but the fruit is almost down to a syrup consistency.
- White granulated sugar – Personally I like my crumble topping to be a lighter color so I prefer to use white. You can easily substitute with light or brown sugar with the same quantity. Take note that brown sugar does contain molasses so it will influence the taste and flavor accordingly.
- Unsalted Butter – I always use unsalted because I like to control the amount of salt I use. If you use salted butter that’s fine just omit salt in the recipe. Margarine or veg shortening works as well but they both will affect the texture of the crumble – margarine has a bit more liquid so you may need to use a tad less. Veg shorting will make the crumble topping more crispy.
- Cornstarch – Peaches are very juicy and the cornstarch help thicken the juices which taste yum.
- Spice mix – Today I’m using ground ginger. But there is so much flavor you can add like pumpkin spice or gingerbread spice as well as Cinnamon.

My mouth is watering just looking at it. I’ve got some heavy whipping cream asking to be made into sweetened whipped cream and what a great place to dollop it — blackberry crumble. I’ll have to look for some.
Absolutely Marisa.. My kids are hooked onto crumble this summer. My Rhea calls the crumble cookie and she loves to make it..
My husband LOVES crumble desserts. I happen to LOVE blackberries too. This would also work with a blackberry/blueberry combo…my two favourite berries in one delicious dessert.
Me too I love crumble very much and now I have my kids hooked on to it too. I have a blueberry crumble too and yes this would be great with so many different combinations. I actually do love Blackberry and Raspberry together – the sweetness of the raspberry and the tartness of the blackberries.. just does it for me lol
