In a medium saucepan, add rolled oats, grated carrot, diced apple, milk, and water. Stir in maple syrup, cinnamon, and vanilla extract.

Place the saucepan over medium heat, stirring occasionally, until it gently bubbles, about 2-3 minutes.

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

If the oatmeal is too thick, add a splash of milk or water to reach desired consistency.

Remove from heat and let sit for a minute. Serve in bowls with toppings of choice.
