In a medium saucepan, combine rolled oats, grated carrot, diced apple, milk, water, maple syrup (or honey), cinnamon, and vanilla extract. Stir well to combine.

Place the saucepan over medium heat and bring to a gentle simmer, stirring occasionally to prevent sticking.

Once simmering, reduce heat to low and cook for 6-7 minutes, stirring frequently until thick and creamy.

Check the consistency, and if too thick, add a splash of milk or water. Remove from heat once desired texture is reached.

Spoon oatmeal into bowls and top with maple syrup, nuts, or fresh berries as desired.
