Ingredients
 
 

  • 240 g oats (rolled or porridge oats, gluten free if required)
  • 75 g soft light brown sugar
  • 100 g vegan butter (the block kind, cold)

Equipment

  • High Speed Cup Blender

Instructions
 

  • Preheat the oven to 170°C fan (190°C conventional / 375°F / gas mark 5).
  • Measure out the ingredients and cut the cold butter into cubes.
  • Measure out 200g of the oats and add them to a blender cup. Pulse for 10-20 seconds until they are the consistency of flour.
    Note:  The texture of the oat flour will not be as fine as regular flour - have a look at the photo for an example of what to expect.

    Vegan butter, oat flour and brown sugar in a bowl ready to be mixed together to make crumble topping.
  • Add the oat flour, brown sugar and cold butter to a bowl and rub together until the mixture is fully combined and no dry sandy mixture remains. It will be the consistency of coarse breadcrumbs with some larger clusters in it (see an example below).

  • Stir through the remaining 40g of whole, unblended oats.

  • To cook, sprinkle the oatmeal crumble topping on top of some cooked fruit and bake it for around 25-30 minutes until the crumble topping is lightly golden. We’ve got a great recipe for apple crumble here.
  • Alternatively, spread the crumble mixture out on a large baking tray lined with parchment paper, in an even, thin layer (you may need to use two trays). Bake in the preheated oven at 170°C fan (190°C conventional / 375°F / gas mark 5) for approximately 15 minutes until it’s starting to lightly colour. Leave the crumble to cool completely and then break up any larger bits. Sprinkle over the top of any dessert you like!
