Mixed berry crumble with coconut oat topping
Juicy mixed berries bubble under a crunchy coconut oil and oat crumble that shatters into buttery-tasting shards — completely dairy-free and dangerously easy to make.

- 680 g frozen mixed berries
- 2 tbs granulated sugar
- 1 tbs cornstarch
- 1 small lemonzested and juiced
- 120 g old-fashioned rolled oats
- 65 g all-purpose flour
- 80 g light brown sugarpacked
- ¼ tsp kosher salt
- ¾ tsp ground cinnamon
- 75 ml coconut oilmelted

Preheat the oven to 190°C (375°F). Place the frozen mixed berries in the baking dish — no need to thaw. Sprinkle the granulated sugar and cornstarch over the berries, then add the lemon zest and lemon juice. Toss everything together until evenly coated.
Tip: Frozen berries work best here — they release juice as they bake, creating that gorgeous syrupy base.

In a large mixing bowl, combine the rolled oats, flour, brown sugar, cinnamon, and salt. Stir to break up any brown sugar clumps. Pour in the melted coconut oil and mix with a fork until the mixture forms chunky, uneven clumps — some sandy bits and some pea-sized clusters are exactly what you want.
Tip: Don't over-mix. Those uneven clumps are what give you both crunchy bits and sandy, crumbly bits in the topping.

Scatter the crumble topping evenly over the berries, breaking up any very large clumps but leaving plenty of texture. Don't press it down — you want air between the clusters for maximum crunch.

Place the baking dish on the sheet pan to catch any bubble-overs. Bake for 28-32 minutes until the topping is deep golden brown and the berry filling is actively bubbling around the edges, thick and syrupy.
Tip: The sheet pan underneath saves you from a messy oven. The filling needs to bubble vigorously — that's how you know the cornstarch has thickened properly.

Let the crumble rest on a wire rack for at least 15 minutes before serving. The filling will thicken as it cools — dive in too early and it'll be soupy.
Tip: Keeps covered in the fridge for up to 4 days. Reheat individual portions in the oven at 175°C (350°F) for 10 minutes to re-crisp the topping — microwaving works but the topping will soften.
