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.
2 cups rolled oats, 1 teaspoon ground cinnamon, 1 teaspoon baking powder, ½ teaspoon ground cardamom, ¼ teaspoon ground nutmeg, ¼ teaspoon fine sea salt, ½ cup chopped 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.
1 cup milk, 1 cup pumpkin puree, ½ cup applesauce, 1 egg, 2 tablespoons maple syrup, 1 teaspoon pure vanilla extract
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.
