This lighter take on a classic jumbleberry crumble keeps plenty of the good stuff — juicy berries, oats and cinnamon — while cutting back on sugar and swapping butter for a cholesterol-free plant oil.
Why this recipe works
Berries bring plenty of natural sweetness, so you don’t need as much added sugar to make this dessert feel satisfying.
Reducing the sugar in both the filling and topping helps bring the overall sugar content down, while oats and wholemeal flour add a little more fibre. Swapping butter for canola or another neutral plant oil also reduces the cholesterol in the crumble itself.

Easy swaps and shortcuts
Use frozen berries: A frozen berry mix can work in exchange for fresh berries.
Cut the sugar further: If your berries are particularly ripe and sweet, try slightly less sugar in the filling.
Make it more oat-y: Replace a little more of the flour with oats for extra texture.
Prefer butter? You can still use a small amount of unsalted butter if you prefer the flavour.
What changes nutritionally?
The original recipe contains approximately:
- 36g sugar
- 84mg sodium
- 20mg of cholesterol per serve
With the reduced sugar and plant-oil swap, this version may bring the sugar down to around 20–22g per serve and remove the unnecessary cholesterol from the butter. Sodium should also remain relatively low when no salt is added.
These figures are estimates and will vary depending on the fruit, brands and exact quantities used.
