Our plum crumble with oats and forest fruits is easy to make in just three steps. 

The oats in this crumble topping are combined with the usual ingredients of butter and sugar but we’ve also opted for wholemeal flour to give a nutty undertone. Oats are a good source of fibre and help reduce cholesterol. 


  • 500g (1lb 2 oz) plums, quartered and stones removed
  • 500g bag frozen forest fruits
  • 100g (3 1/2oz) golden caster sugar
  • 1/2tsp ground cinnamon

For the topping:

  • 150g (5oz) plain wholemeal flour
  • 125g (5oz) chilled butter, cubed
  • 100g (3 1/2oz) oats
  • 100g (3 1/2oz) golden caster sugar




  1. Heat the oven to 190C (170C fan, Gas 5). Put the plums and forest fruits into the base of an ovenproof dish. Sprinkle over the golden caster sugar and cinnamon and gently mix together.
  2. Put the flour into a bowl (or processor) and add the butter. Rub together with your fingertips until the mixture resembles crumbs (or pulse for a few secs in a processor).
  3. Add the oats and sugar and stir together. Sprinkle over the fruit. Bake for 30 minutes until the fruit is tender and the crumble is cooked through.

Top tips for making plum crumble with oats

This crumble is brilliant with fromage frais or custard on the side. We've used fresh plums in this recipe to get the most out of the season's fruit but as plums are most ripe between late August and early October, you can use frozen ones too.

Can you prepare a plum crumble with oats ahead of time?

You can assemble the crumble a day ahead and then bake around an hour to 40 minutes before you’d like to serve it. We recommend serving crumble warm but not too hot for the best flavour and eating experience. 

What fruit goes with plums in a crumble?

We have used a selection of frozen forest fruits but you could of course use apples along side the plums if you like. Pears are another great choice or blackberries add a gorgeous colour to the mix. 

What can I use instead of cinnamon?

You could use ground ginger in this recipe if you prefer the taste. Ginger and plums is a wonderful combination. You could also use a little pinch of mixed spice or star anise. If you opt for ginger, consider dicing some stem ginger and adding to the crumble topping too. 

The quickest way to combine the topping ingredients is by using a food processor. Read our full Ninja 3-in-1 food processor review if you need some convincing before you make the investment.
