Heat the oven to 180C/160C fan/gas 4. Line a baking tray with baking parchment.
Sift the flour into a bowl. Mix in the baking powder, porridge oats and sugar.
Melt the butter, syrup and milk in a small saucepan or in the microwave and stir.
Add to the dry ingredients. Mix until the liquid covers all the oat mixture and until well combined.
Spoon onto a baking tray and shape into rounds, leaving space between each biscuit as they will spread whilst cooking.
Bake for 10-15 mins, or until golden brown. Leave to cool for 5 mins before removing from tray.
