01 - Preheat oven to 350°F. Grease a 9x9-inch baking dish with coconut oil or butter and set aside.
02 - In a large mixing bowl, whisk together the eggs, milk, maple syrup, melted coconut oil, and vanilla extract until fully blended and smooth.
03 - Add the finely grated carrots to the wet mixture and stir until evenly distributed throughout.
04 - Add the rolled oats, baking powder, cinnamon, ginger, nutmeg, cloves, and salt. Stir thoroughly until all dry ingredients are uniformly incorporated.
05 - Gently fold in the chopped walnuts and raisins, if using, until evenly dispersed throughout the batter.
06 - Pour the oat mixture into the prepared baking dish, spreading it into an even, uniform layer across the entire surface.
07 - Bake on the center rack for 35 to 40 minutes, until the top is golden brown and the center is fully set with no jiggle.
08 - Allow the baked oatmeal to rest for 5 to 10 minutes before slicing into portions. Serve warm, topped with yogurt, additional nuts, or a drizzle of maple syrup if desired.
