Place all ingredients into a saucepan. Bring to the boil, lower heat and simmer gently until all the liquid has absorbed. Add the extra milk if needed.
Alternatively, cook in a microwave for 1:30 minutes. Stir and microwave again for a further 30 seconds until cooked through.
Top with crushed hazelnuts and extra milk if needed
Notes
Keep an eye on the consistency when cooking the oats, cook to your preference.
