1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
3. In a large bowl, combine the granulated sugar, brown sugar, and vegetable oil. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
4. Gradually add the dry ingredients to the wet mixture, stirring just until combined.
5. Fold in the grated carrots, crushed pineapple, walnuts, and raisins (if using).
6. Divide the batter evenly between the prepared cake pans. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
7. Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.
8. For the cream cheese frosting, beat the softened cream cheese and butter together until smooth and creamy. Gradually add the powdered sugar, beating until well combined. Stir in the vanilla extract.
9. Once the cakes are completely cool, spread a layer of frosting on top of one cake. Place the second cake on top and frost the top and sides of the cake.

As your cake bakes, your kitchen will be filled with the comforting aromas of spices and sweetness—a reminder that home cooking is all about creating those cozy, memorable moments.
