In a medium saucepan, combine the rolled oats, milk, and a pinch of salt.

Bring the mixture to a gentle simmer over medium heat, then reduce to low and cook for 5 to 7 minutes, stirring occasionally until creamy.

While the oats cook, melt the butter in a non-stick skillet over medium-high heat.

Add the diced apples, brown sugar, and cinnamon to the skillet.

Sauté the apples for 5 to 8 minutes, stirring frequently, until the fruit is tender and the sugar has thickened into a caramel coating.

Stir the vanilla extract into the finished oats.

Divide the oatmeal into two serving bowls and top with the caramelised apple mixture.
