Making Carrot Cake Baked Oatmeal is easy if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and lightly grease a baking dish (about 9×9 inches or similar size).
2. Combine Dry Ingredients: In a large bowl, mix together the rolled oats, baking powder, cinnamon, nutmeg, and salt.
3. Mix Wet Ingredients: In a separate bowl, whisk together the milk, eggs, brown sugar, and vanilla extract until well combined.
4. Add Carrots and Nuts: Stir in the grated carrots and chopped nuts into the wet mixture.
5. Combine Mixtures: Pour the wet ingredients into the dry ingredients. Stir gently until everything is evenly combined.
6. Optional Add-ins: If desired, fold in raisins or shredded coconut at this stage for extra flavor and texture.
7. Transfer to Baking Dish: Pour the combined mixture into the greased baking dish, spreading it out evenly.
8. Bake: Place in the preheated oven and bake for 30-35 minutes, or until the top is lightly golden and a toothpick inserted in the center comes out clean.
9. Cool Down: Remove from the oven and let it cool for about 5-10 minutes before slicing.

These steps will guide you to create a hearty and delightful baked oatmeal that perfectly combines the flavors of carrot cake with the wholesome qualities of oats.
