Berry crumble is the summertime cousin of apple crisp — just as easy but with a vibrant, fruity personality all its own. A rainbow of blueberries, raspberries, blackberries, and strawberries bubble together beneath a golden, almond-studded crumble topping.
The beauty of this dessert is its flexibility. Use whatever berries look best, fresh or frozen. The topping comes together in minutes, the berries need virtually no prep, and the oven does all the heavy lifting. Add a scoop of vanilla ice cream and you have a dessert that tastes far more impressive than the effort involved.
This crumble works year-round thanks to frozen berries, but it truly shines in the height of summer when berries are at their peak.

This is best served the day it is made while the topping is still crunchy.
Storage
Cover and refrigerate for up to 3 days.

Reheat in a 350°F oven for 10-15 minutes. The topping will re-crisp in the oven.

Frequently Asked Questions
- Can I use all one type of berry?
- Yes, though a mix creates the most interesting flavor. All-blueberry or all-raspberry crumbles are excellent.
- Can I make this gluten-free?
- Yes. Swap the all-purpose flour for more almond flour or a gluten-free flour blend and use certified GF oats.
- How do I prevent a soggy bottom?
- The cornstarch helps thicken juices. Also, bake until you see the filling actively bubbling — this means the thickener has activated.
