Preheat the oven to 375 degrees Fahrenheit and grease a 13 x 9-inch rectangular baking pan with coconut oil or another wholesome fat of your choosing.
Meanwhile beat together eggs, milk, maple syrup (if you’re using it), until well-combined and frothy.
Pour the mixture of eggs, milk and maple syrup over the soaked oats and nuts, stirring well to combine into a porridge-like mixture.
Gently fold dried fruit, cinnamon and coconut oil into the porridge-like mixture.
Pour the mixture into a greased baking pan and smooth it out with a rubber spatula to ensure even baking and a good appearance.
Bake in an oven preheated to 375 degrees Fahrenheit for forty to forty-five minutes or until the oatmeal achieves a pleasing golden-brown color on top, a knife inserted into its center comes out clean and free from liquid and the fragrance of baked oats, dried fruit and cinnamon perfumes your kitchen.
If you can bear the wait, allow the baked oatmeal to cool for five to ten minutes before cutting into squares and serving.
