A summer blackberry and blueberry crumble
It’s been a while, I know. But, I am so, so happy to be (finally!) back in this space after a long month of transition. Moving across the country, living out of a suitcase for weeks, finding a house in an unfamiliar city, the seemingly impossible task of unpacking and organizing all of our possessions… (why do we own so much stuff??) It’s been fairly overwhelming.
Life is beginning to settle into a normal rhythm, day by day. There’s a certain comfort in just getting back to the ordinary routine of cooking and eating at home instead of out for every meal. Of picking clothes to wear from the closet instead of out of a suitcase. The Honey started his new job, and I’m enthusiastically back at work too, cooking, baking, photographing and writing.
I’m slowly learning the layout of the grocery store and managing not to get lost while running errands. We’re enjoying the last few weeks of this spectacular Pacific Northwest summer; Taking the pup for a swim in the sound on warm afternoons and exploring the farmer’s market on Saturday mornings. Simply soaking in the sunshine before the grey skies and rain set in.
About this blackberry and blueberry crumble
Between the bulging pallets of blueberries, blackberries and raspberries we pick up at the farmers market each week and the wild blackberries growing in every inch of available land they manage to sink their roots into, I’ve been in berry-hoarding heaven lately. I’m altogether obsessed, and our freezer is already filling up with ziplocs of sweet berries.
The first bit of baking I did in our new kitchen was this blackberry and blueberry crumble. It’s the sort of thing that’s perfect for summer; utilizing fresh, seasonal fruit, quick to make and so simple it barely requires a recipe. It’s also a dessert worth turning on the oven for on a stiflingly-hot August afternoon.
Simply being back in the kitchen – cooking again – starts to make our little blue house at the end of the cul-de-sac, surrounded by wild blackberries and towering pines, feel like home. Of course, the aroma of a berry crumble baking away in the oven helps quite a bit too.

Description
A simple blackberry and blueberry crumble with a sweet and tart fruit filling and buttery brown sugar oat crumb topping. So easy to prepare and perfect for Summer. Vegan and gluten free friendly.
Ingredients
Blackberry and Blueberry Filling
- 4 cups blackberries and blueberries ¹
- zest of 1 small lemon
- 2 Tbsp granulated sugar
- optional: 1 Tbsp arrowroot starch ²
Crumble Topping
- 1/2 cup (old-fashioned) rolled oats
- 1/4 cup all-purpose flour ³
- 1/3 cup brown sugar
- pinch of Kosher salt
- 3 Tbsp cold-pressed, unrefined coconut oil, at room-temperature
Instructions
- Preheat the oven to 375℉. Toss together the mixed berries, lemon zest, and sugar. Fill a baking dish with the berries. Set aside.
- In a small mixing bowl, whisk together the oats, flour, brown sugar, and salt until combined. Add the coconut oil, and use a pastry blender or the back of a fork to cut the oil into the dry ingredients. Continue until the oil is completely incorporated, and the mixture comes together into a chunky crumb. Crumble the topping over the berries.
- Bake for 30-40 minutes, until the crumble topping is golden brown and the berry juices begin to bubble up around the edges. Remove from the oven and let cool for 15 minutes. Serve warm with scoops of vanilla ice cream. Enjoy!!
Notes
¹ Use an even mix of blackberries and blueberries, or your preferred ratio and favorite combination of summer berries.
² Arrowroot starch is my thickener of choice for pies and fruit fillings. It’s a natural plant-based starch that creates a smooth, shiny sauce without a noticeable taste. You can also use cornstarch or tapioca flour.
³ Make it gluten free: Use an all-purpose gluten free flour blend instead of the all-purpose flour, and be sure your oats are also certified gluten free. Almond flour would also likely work here.

Has anyone tried this recipe using frozen berries? I’m hoping to bring on a the taste of summer on this cold winter day in the Southern Hemisphere!
Hi Denise! You can definitely use frozen berries, the filling may just end up a bit juicier. I would just be sure to add the arrowroot starch 🙂 Enjoy!
Thanks. It turned out great!

Yay! Thanks, Denise!!
What size pan for the 2x recipe?
★★★★★
Hi, Kellianne! I would use either an 8×11-inch or 9×13-inch for a double batch. Enjoy!
Great recipe! The family gobbled it up. 😊 I was hoping to have some leftovers to top a smoothie bowl at breakfast, but the entire dish was gone in 10 minutes.

A delicious problem to have… 😉
Wild blackberries have been my favorite thing about Western WA for 52 years. So, and, No disrespect intended but in light of the description of where you live, please check your trees again. Pine? Coastal Washington? Might they be fir?
This was delicious! I added a little cinnamon & we loved it.

Thank you so much, Rose!!
Is that 4 cups EACH of Blueberries AND Blackberries, or is it simply 4 cups total of Berry mixture?
Hi . . . making the Blackberry Blueberry Crumble ( because our gardens are full of both now) and I noticed the crumble topping calling for 3/8 cup brown sugar. I’m assuming that is rather 3/4 cup, right? I’ve never seen a 3/8 cup in a recipe before. Anyway, going for the 3/4 cup . . . fingers crossed and it sure looks and sounds great!
Hi Robert! It should actually be 3/8 cups brown sugar, which equals 6 Tbsp. I know it may be an unusual measurement and I’m sorry if that wasn’t clear! (I’ll update the recipe notes) That being said, crumbles are pretty forgiving, and a little extra brown sugar isn’t a bad thing… 😉
How did it turn out for you?

Glad to have you back Laura! And what a great way to come back, this crumble is everything I love about summer — a summer I’m not quite ready to let go of…
Thanks, Nicole!! 🙂 I’m totally not ready to let go either…
Fruit crumbles never get old. This looks delicious!
Thanks, Jenna!! 🙂
Beautiful pics Laura. And welcome to the Pacific Northwest! I hope you enjoy it as much as we do.
Thank you so much! My husband is from the Pacific Northwest (Oregon) and he is so happy to be back, and I am loving it more every day!
This is beautiful. I hope you get settled in soon. Moving is a pain. Glad you’re home now 🙂

Thanks so much, Christina!!
I totally know the feeling. My wife and I finally are starting to feel a bit settled and “home” with our new house. We’ve been eating out almost every meal for a month, and it felt so good last night to cook together, in our new kitchen. Those berries are stunning, as is this dessert!
Thank you, and congrats on settling in to your new house! It’s funny how those little things – like cooking together – can make all the difference.
Love the idea of oats for the crumble. Berry crumble would have to be my favourite dessert – after chocolate of course.
Thanks, Caroline! I love crumbles and crisps with just about any type of fruit… but yes, chocolate has also reserved a special place in my heart above all 🙂
