Preheat the oven to 170C fan-forced and grease and line a loaf tin with paper so it extends over the long sides.
Use a Thermomix, food processor, mixer or good old spoon to combine all the ingredients.
Transfer the batter into the tin and smooth out the top.
Bake for 75 mins or until a cake tester inserted in the middle comes out clean.
Leave to rest in the tin for 10 mins and then transfer to a wire rack to cool completely.
Serve sliced at room temperature or toast slices and serve spread with butter.
Notes
STORAGE: Store in an airtight container at room temperature for up to 2 days. Refrigerate for up to 4 or cut in slices and freeze. Put a piece of baking paper between slices to stop them sticking.
