In a small saucepan, melt 1 tablespoon of unsalted butter, then stir in 1 tablespoon of maple syrup, ¼ teaspoon of salt, and 1 teaspoon of cinnamon. Add in the diced apples, and sauté for a few minutes until the apples have softened slightly, but have still retained their shape. Set aside.
Meanwhile, while the apples are cooking, bring 1.5 cups of water, 1.5 cups of milk, and ¼ teaspoon of kosher salt to a soft boil over medium-low heat in a dutch oven or large saucepan. Add in 2 tablespoons of brown sugar, and stir to dissolve.
Add in 1 cup of oats and 2 tablespoons chia seeds, and simmer for about 5-10 minutes, stirring occasionally to thicken.
Stir in the 2 teaspoons of vanilla extract, and 1.5 teaspoons of ground cinnamon, along with about half of the cooked apples, reserving some for topping. Simmer for another 3-5 minutes to thicken, or until the desired consistency is reached.
Now, pour on a little fresh cream or another splash of milk, the apple topping, more cinnamon and your favorite toppings. Enjoy!
Store leftovers in an airtight container in the fridge for 4-5 days. Reheat gently in the microwave or on the stovetop. Do not freeze.
