01 - Preheat oven to 350°F. Grease a 9x9-inch baking dish with butter or coconut oil to prevent sticking.
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 - Stir in the rolled oats, baking powder, cinnamon, ginger, nutmeg, cloves, and salt. Mix until all dry ingredients are thoroughly incorporated and no dry pockets remain.
05 - Gently fold in the chopped walnuts and raisins, if using, distributing them evenly throughout the batter.
06 - Pour the oat mixture into the prepared baking dish and spread it into an even layer using a spatula.
07 - Bake for 35 to 40 minutes, or until the top is golden brown and the center is firmly set. A toothpick inserted in the middle should come out clean.
08 - Allow the baked oatmeal to cool for 5 to 10 minutes before slicing into portions. Serve warm, topped with yogurt, additional nuts, or a drizzle of maple syrup if desired.
