Take out a large mixing bowl. Pour in the oatmeal. Add the cocoa powder, almonds, walnuts, and a pinch of salt. Mix thoroughly.
Heat the coconut oil and honey together in a saucepan. Do not boil, just warm it up! Pour it over the oat mixture.
Take a baking tray lined with baking paper and spread the mixture evenly over it. Place in an oven preheated to 180 °C or 350°F and bake for 20-25 minutes. Stir once during baking.
When ready, leave to cool on the baking tray, then transfer to sealable glass jars. When you fancy some granola, just take some out.
