In a small saucepan, whisk together the milk, egg, brown sugar, and salt.

Turn the heat on to medium, and don't go higher than that the whole time you are cooking otherwise it will turn out grainy.

Mix in the oats. Stir occasionally. When the oatmeal begins to bubble, cook and stir until thick.

When it has reached the consistency you like, remove from heat, and stir in butter until melted.

I usually let it sit off the heat with a lid on for a couple minutes so that it gets nice and thick. Serve with milk and fruit!
