In a medium saucepan, combine the rolled oats, chopped apples, milk, water, brown sugar, vanilla extract, sea salt, and apple pie spice. Stir well to combine.
Heat oatmeal over medium heat until it boils, then reduce the heat and simmer for 8-10 minutes, stirring occasionally.
Once the oatmeal reaches your desired consistency, remove it from the heat and serve immediately with chopped walnuts or pecans and a splash of milk or cream.
Store leftovers in the refrigerator for 3-4 days. Add a splash of milk or water when reheating to restore the creamy texture.
Notes
The nutritional information does not include toppings. It’s only for the prepared oatmeal.
The nutritional information was calculated using 2% milk.
You can use 2 cups of milk instead of 1 cup milk and 1 cup water if you prefer. Using all milk will yield a thicker and stickier oatmeal.
