Measure 50 grams of oats and 250 ml of milk or water (for a creamier texture, use milk) in a saucepan.
Place the saucepan on medium heat and bring the mixture to a gentle boil, stirring occasionally to prevent sticking.
Reduce the heat to low and let the oatmeal simmer for 5-7 minutes, or until the oats have absorbed the liquid and reached your desired consistency. Stir occasionally to ensure even cooking.
Remove the saucepan from the heat and let the oatmeal rest for 1-2 minutes to thicken.
Transfer the oatmeal porridge to a serving bowl and add your choice of toppings, such as chopped fruits, nuts, seeds, honey, or a pinch of cinnamon.
