Packed with a mix of summer berries and piled high with buttery streusel, this mixed berry streusel crumble is a quintessential easy dessert for summer!
By this point we are all extremely familiar with my ONE go-to/absolutely gotta have summer dessert, yes?
I’ll give you an easy hint: it involves tons of fruit. And even more tons of streusel.
Give up? It’s a crumble. Or a crisp. Or whatever you wanna call it, it’s just plain and simple summer heaven.
Heaven tastes pretty good, FYI. Especially when it’s a mix of summer berries and covered in piles of buttery oat streusel. <<< the.best.period.
Okay, so as appearances would suggest, this mixed berry streusel crumble is seriously no biggie to throw together. Steps are as follows —>
- Berry filling. Raspberries, blueberries, sugar, lemon juice, and cornstarch cooked right on the stove in 5 minutes. It’s honestly that easy.
2. Streusel time which = the best time. Oats, almonds, flour, sugar, cinnamon, and melted butter in one bowl.
Throw your filling in the pan and top with an abundance of streusel topping. It’s okay to swoon a little bit.
Less than THIRTY minutes later…feast your eyes upon your new form of summer heaven. It’s pretty sweet.
It’s also pretty insanely good warm from the oven…straight from the pan…with your biggest spoon and with little to zero shame. ??

Yes! Summer is not complete with ALL of the crisps and crumbles! They’re my favorite type of dessert, and this mixed berry one looks amazing! I’m swooning over that crumbly topping. Just gorgeous, Sarah!

This screams summer to me! Beautiful pictures, I wish I had the whole crumble in front of me right now 🙂

Good recipe but – Frozen raspberries & blackberries turn to puree (mush) when simmered. Personally I’d only use blueberries, strawberries and peaches if cooking with frozen.

Thanks for the review, Carrie! I personally like it when the raspberries and blackberries break down like you described, but I definitely get it that it’s not for everyone! Thanks for stopping by and for making this crumble! 🙂
