I love making muffins. They appeal to the slapdash side of me that can't rear its head during normal baking activities. No need to weigh anything, or even mix it that well. In fact, the less you stir, the better: muffins like to be largely ignored. Lumpy mix makes for fluffy results.
These ones are even a bit good for you - full of oats and wholegrain flour, with canola oil instead of butter. They are practically perfect.
They freeze well too, given half the chance.
