Creating the Perfect Carrot Cake is easy if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and sugar.
3. Combine Wet Ingredients: In another bowl, whisk together the oil, eggs, grated carrots, pineapple, and vanilla extract until well blended.
4. Combine Mixtures: Gradually pour the wet ingredients into the dry mixture, stirring until combined.
5. Add Nuts: Fold in the chopped walnuts or pecans if using.
6. Divide Batter: Pour the batter evenly into the prepared cake pans.
7. Bake: Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
8. Cool: Allow the cakes to cool in the pans for about 10-15 minutes, then transfer to wire racks to cool completely.
9. Prepare Frosting: In a medium bowl, beat the cream cheese and butter together until smooth. Gradually mix in the powdered sugar and vanilla extract until creamy.
10. Assemble Cake: Once the layers are completely cooled, place one layer on a serving platter. Apply a generous amount of frosting on top, then place the second layer on top. Frost the top and sides of the cake.
11. Decorate: Optionally, decorate the top with additional walnuts or shredded carrots for a beautiful finish.
