Preheat the oven to 375°F and lightly coat an 8x8 or 1.5-quart baking pan with nonstick spray.
In a small bowl, mix together oats, spices, baking powder, and pecans.
In a large bowl, whisk together milk, pumpkin, applesauce, egg, maple syrup, and vanilla until blended. Add the dry ingredients and stir until incorporated.
Pour mixture into prepared pan and bake for about 30 minutes, until browned and edges just start to pull away from the pan. Let cool slightly and serve with maple syrup.
