If you don't like the idea of the brown sugar and the cinnamon on top of the muffins then you can ice them instead. Mix 2 tablespoons of water and 120g of icing sugar in a bowl and mixture until smooth and glossy. Drizzle the icing on to the muffins when they are cool.
Lovely and light muffins. Perfect for afternoon tea. I used melted butter instead of solid. - 17 Feb 2018
Very light and moist texture but not hugely appley ... will throw in a few sultanas next time. - 17 Oct 2016
Couldn't really taste Apple as the cinnamon dominated the flavour however the muffins are very moist and I will try making them again but use fresh apples - 24 Nov 2015
