Peel and dice the apples. Place a skillet over medium high heat. Add the butter and allow to melt. Add the apples to the skillet and let sauté for a couple of minutes until they begin to soften. Stir in the brown sugar, cinnamon and kosher salt.
Continue cooking the apples until they are tender. Set aside and allow to cool slightly before proceeding.
Baked Oatmeal
Preheat the oven to 375°F. Spray an 11" by 7" baking dish with non-stick spray. Set aside.
In a mixing bowl, whisk together the milk and eggs. Stir in the brown sugar. Add the oatmeal, baking powder, cinnamon, allspice, and kosher salt and stir together. Stir in the melted butter along with one third of the caramelized apples.
Pour the oatmeal mixture into the prepared baking dish. Bake for 25 to 30 minutes until the oatmeal is set in the middle. Let cool for 5 minutes before serving.
Reheat the remaining caramelized apples. Cut the baked oatmeal into portions. Top the baked oatmeal with the warm caramelized apples and enjoy!
