Lightly sweet, perfectly spiced and dotted with plenty of tart apples, this apple cinnamon baked oatmeal is the perfect treat to enjoy on a chilly autumn morning! Cinnamon, brown sugar and apples are an impeccable combination, and when paired with the chewy, slightly crunchy oatmeal, this entire dish comes together to create the ultimate comforting fall breakfast.
Preheat your oven to 350 °F and lightly grease a 9x13 inch glass baking dish.
In a large bowl, whisk together the brown sugar, oil and eggs. Add the salt, baking powder, ground cinnamon and rolled oats and stir until fully combined. Fold in the diced apples and chopped walnuts.
Pour the mixture into your prepared pan and use the back of a spoon or measuring cup to firmly press the mixture into the pan. Sprinkle the top with extra nuts if desired before baking for about 30 minutes or until the oatmeal is lightly golden brown. Allow the oatmeal to cool for at least 10 minutes before spooning into bowls and serving warm.
