In a medium saucepan, add rolled oats, grated carrot, diced apple, milk of choice, water, maple syrup (if using), cinnamon, and vanilla extract. Stir everything together until well blended.

Set the saucepan over medium heat and bring the mixture to a gentle simmer. Stir occasionally to prevent sticking.

Allow the oatmeal to cook for about 6-7 minutes, stirring occasionally until the oats are tender and the mixture thickens.

Once cooked, dish out the oatmeal warm into bowls. Top with your choice of maple syrup, peanut butter, fresh berries, banana slices, raisins, or chopped nuts.
