Preheat oven to 375 F and grease a baking dish (either 8 x 8-inch, or 8 x 5-inch). In a large bowl, combine oats, apple pie spice, and baking powder. Set aside!
Then, in a separate bowl, whisk together milk, an egg, honey or pure maple syrup, vanilla extract, and apple sauce until well combined. Gently stir the oat mixture with the milk mixture until incorporated. Pour into reserved greased baking dish.
Bake for about 35-40 minutes or until a toothpick inserted in center comes out mostly clean. Let cool at room temp for at least 10 minutes before serving -- or overnight, loosely covered.
Meanwhile, prepare the caramelized apples. In a large no stick skillet, melt unsalted butter over medium heat, stir in honey, and cook apples for about 5-7 minutes or until golden brown.
Top apple spice baked oatmeal with caramelized apples. If desired, garnish with pomegranate seeds. Serve with Bigelow's Classic Green Tea and enjoy!
