Overnight oats have become a popular breakfast option over the last few years but this cold oatmeal dish has in fact been around since the early 1900s.
The original overnight oats - bircher muesli - was created by a Swiss doctor/nutritionist named Maximilian Bircher-Benner. He treated his patients with a mixture of oats, nuts, and fruit that steeped in milk overnight. The oats become a pudding-like porridge by the morning. There is no cooking involved.
