Walnut Free Mixed Berry Crumble with Coconut & Cassava Topping
Bubbling fruit filling peeking through a golden, crackly topping — this berry crumble is the kind of dessert that makes everyone hover near the oven. The filling leans on fresh or frozen mixed berries, a touch of maple syrup, and arrowroot starch to create a jammy, glossy base that thickens beautifully as it cools. What makes this crumble genuinely special is the topping: cassava flour and tapioca starch give it a tender, slightly chewy bite, while shredded coconut adds texture and a subtle tropical warmth that sets it apart from any standard oat crumble. Solid coconut oil is worked in until the mixture forms those irresistible pea-sized clumps that turn golden and crisp in the oven. For anyone navigating tree nut concerns, crumble toppings can be a minefield — many rely on almond flour or chopped walnuts — but every ingredient here is completely clear of that. Ceylon cinnamon and ground ginger round out the spice profile with a gentle, aromatic heat that complements the tart berries without overpowering them. Let it rest for ten minutes after baking and the filling sets into something truly spoonable and satisfying.
