Prepare the apples: Peel, core, and dice the apple into small pieces. Set aside.
Cook the oats: In a medium saucepan, add the rolled oats and milk (or dairy-free alternative).
Stir occasionally and bring to a simmer over medium heat.
Let it cook for 5-7 minutes, or until the oats are soft and have absorbed most of the liquid.
Add apples and cinnamon: Once the oats are cooked, add the diced apples, ground cinnamon, and a pinch of salt if using.
Stir everything to combine and cook for an additional 1-2 minutes to warm the apples.
Sweeten and finish: Add honey or maple syrup if you like a sweeter version of the dish.
Stir in butter for a creamier texture, if desired.
Serve: Spoon the oats into bowls and top with your favorite toppings like chopped nuts, dried fruit, or a dollop of yogurt.
Enjoy warm!
