Muffins

I have ambitions to make really good muffins and came across a simple muffin recipe online which I've been wanting to try for a while now.

Its just: 300g self raising flour
            150 g sugar
            1 medium egg
             175 ml milk
            125 ml vegetable oil
I mixed in a few handfuls of porridge oats, lots of raisins and sultanas and some chopped up plain chocolate as well as a pinch of salt and topped the batter with brown sugar before baking.

I'm irrationally pleased with them and sent Giles home with a box which he's meant to share and save for breakfast...
