Preheat the oven to 180C/350F/Gas Mark 4
Put a small piece of grease proof paper on a baking tray.
In a small bowl combine flour, cinnamon, nutmeg, salt, and baking soda.
In another small bowl combine the butter and sugars to a creamy consistency. Add milk and vanilla extract and mix.
Add flour mix to butter mixture and mash together to get everything combined.
Add the oats and raisins and mash again, the mixture will still be crumbly but should hold together when squished with your fingertips.
Gather the dough together with your hands and roll into a ball.
Place on prepared baking sheet and flatten with your fingertips to about a centimetre thick.
Put in the oven for 11-13 minutes, depending whether you like your cookies super soft or chewy. (keep in mind that these cookies get more crunchy and hard when cooled)
Let cool for a few minutes before transferring to a wire rack to cool completely.
