Preheat oven to 350°F. Lightly grease or spray with nonstick cooking spray an 8-inch square baking dish (or a comparably sized 2-quart baking dish).
In a large bowl, combine oats, almonds, cinnamon, and salt. Mix in diced peaches, milk, eggs, maple syrup, vanilla, and almond extract. Stir in coconut oil until all ingredients are well combined.
Spread oatmeal into prepared baking dish and bake for 25 minutes or until set and light golden brown on top. Allow to cool in the baking dish for at least 5 minutes before slicing. Serve warm with optional garnishes: warm milk or cream drizzled over the top, maple syrup, additional toasted nuts or diced peaches.
