Preheat the oven to 350 F.
Grease a 9×9 baking dish with spray oil.
Mix all dry ingredients together, including pecans.
Except for the maple syrup, mix together the remaining ingredients, and beat in eggs one at a time.
Combine the wet ingredients with the dry ingredients and let sit for 5-10 minutes, allowing the oats to soak up the mixture.
Transfer to a greased baking dish; ensure the mixture is spread out evenly. Drizzle with the maple syrup.
Bake for 30 minutes, until the top, starts to brown and the oatmeal has set.
Once cooked, allow the dish to cool completely before cutting. Unless serving right away, give it 10-15 minutes to cool before cutting.
Using a sharp knife cut around the edges of the dish first, and cut into 9 portioned squares.
