Preheat oven to 375° F. Spray a 9 inch pie dish with cooking spray and set aside. In a medium size bowl, combine dry ingredients: apples, oatmeal, baking powder, spices and salt. In another small bowl, combine wet ingredients: milk, eggs, maple syrup, oil and vanilla extract. Stir wet ingredients until well combined. Pour wet ingredients into the dry ingredients and stir well to combine. Pour mixture into prepared pie plate and bake on a cookie sheet for 45 minutes; cover with foil for the last 5 minutes if top is getting to brown. Cool on a baking rack for 10 minutes. Cut into wedges and serve with a dollop of low fat whipped cream, a drizzle of maple syrup or eat as is.
