Oatmeal will give an incredible crunchy texture to your fruit crumbles. Combine all ingredients, that’s all. Put fruits in a baking pan cover with the crumble topping and bake.
Cut cold butter into cubes. Pour the dry ingredients (sugar, flour and oatmeal) into a container.
Gently combine with your fingertips (so that butter won’t melt in contact with the heat of your skin) or with a food processor. See on the pics underneath the texture you should get. The idea is to break butter into small parts that will be coated with the other ingredients, not to have a very homogeneous paste.
Then arrange chosen fruits in a baking tin.
Cover with the crumble topping without pressing. Bake at 180°C for about 30 min.
Notes
Baking time depends on the type of fruit you use and how ripe they are.
