Preheat the oven to 350°F and spray an 8x8 inch square baking dish with cooking spray.

To a mixing bowl, add the oats, grated carrots, protein powder (if using), flaxseed, baking powder, cinnamon, ginger, nutmeg, and salt. Stir to combine.

Add in the almond milk, applesauce, maple syrup, and vanilla. Stir well to combine.

Fold in the chopped walnuts and raisins.

Pour batter into prepared baking dish and bake for 45-50 minutes, until the top is golden brown. The baked oatmeal will be a little soft to the touch but should be cooked through.

While the oatmeal is baking, prepare the frosting. In a small bowl, combine the softened cream cheese, whipped topping, maple syrup, and vanilla and whisk until smooth. The frosting is lightly sweet as is; add an additional splash of maple syrup if you like it sweeter.

Remove baked oatmeal from the oven. Let cool for about 15 minutes before spreading on the frosting and cutting into squares. Enjoy!
