01 - Preheat oven to 350°F. Grease a 9x9 inch baking dish with butter or nonstick spray.
02 - In a large mixing bowl, stir together the oats, cinnamon, nutmeg, ginger, baking powder, and salt until evenly distributed.
03 - In a separate bowl, whisk together the eggs, milk, maple syrup, vanilla extract, applesauce, and melted coconut oil until smooth and well blended.
04 - Pour the wet mixture into the dry ingredients and stir gently until just combined. Avoid overmixing.
05 - Gently fold in the grated carrots, chopped nuts, raisins, and shredded coconut until evenly dispersed throughout the batter.
06 - Pour the batter into the prepared baking dish and spread evenly. Smooth the surface with a spatula for uniform baking.
07 - Bake for 35 to 40 minutes, or until the top is golden brown and the center is fully set. A toothpick inserted in the middle should come out clean.
08 - Allow the baked oatmeal to cool for 10 minutes before slicing into portions. Serve warm or at room temperature.
