Step 1

Preheat your oven to 180°C (350°F) and line a baking tray with parchment paper.

Step 2

Combine the butter, flour, oats, sugar, and salt in a food processor.

Step 3

Pulse it repeatedly until you see some big clumps of dough appearing.

Step 4

Use your fingers to separate the bigger clumps of dough (i.e., forming the crumble) and distribute them on the lined baking tray.

Step 5

Place the crumble in the oven for 20 to 25 minutes or until golden.

Step 6

Take the tray out of the oven and set it aside to cool.

Step 7

You can now enjoy your oatmeal crumble!
