Follow these easy steps to create your incredible Carrot Cake:

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, whisk together the flour, sugar, baking soda, baking powder, salt, cinnamon, and nutmeg.
3. Combine Wet Ingredients: In another bowl, beat the eggs and mix in the oil until smooth.
4. Add Carrots & Pineapple: Stir in the grated carrots and crushed pineapple into the wet mixture.
5. Combine Mixtures: Gradually fold the wet ingredients into the dry mixture until well combined. Be careful not to overmix.
6. Add Nuts and Raisins: Gently fold in walnuts and raisins if you're using them.
7. Divide Batter: Pour the batter evenly into the prepared cake pans.
8. Bake: Bake for 40-45 minutes or until a toothpick inserted into the center comes out clean.
9. Cool Cakes: Remove from the oven and let the cakes cool in the pans for about 10-15 minutes, then transfer them to wire racks to cool completely.
10. Prepare Frosting: While the cakes cool, beat the cream cheese and butter together until creamy. Gradually add in the powdered sugar, then mix in vanilla extract until smooth.
11. Frost the Cake: Place one cake layer on a serving platter, spread a layer of frosting on top, then place the second layer on top and frost the top and sides of the cake.
