Beat the butter with the sugar and oil until it becomes lighter in colour and looks fluffy.
Add the eggs and beat again until it looks fluffy again. If you're using a stand mixer, remember to stop halfway through to scrape down the sides and bottom of the bowl.
Add the honey and beat to mix. Repeat with the salt, baking powder and milk.
Finish by adding the flour and mixing them in with medium speed. Just mix it enough so that it looks homogeneous; if you beat it too much the dough will turn tough.
Cut baking paper to the size of your 11x22cm / 8x4in pan and stick it in place with a bit of vegetable oil.
Pour the batter into the pan and level it out with a spatula.
Bake the loaf in a preheated oven at 180°C/350°F for 45 minutes initially. If your oven is electric and has bottom and top heat, switch it to bottom heat only at this point and cook it for an extra 15-20 minutes or until you can insert a thin knife at the centre and it comes out clean. If you have a gas oven, cook it in total 1h - 1h15 minutes or until you can insert a thin knife at the centre and it comes out clean.
Let the loaf cool down completely and unmould it.
