Step 1: Preheat and Prepare: Preheat the oven to 350F (175C). Grease and flour a 9x13 inch baking pan or two 9-inch round cake pans. This prevents the cake from sticking and ensures easy removal.
Step 2: Combine Dry Ingredients: In a large bowl, whisk together the flour, baking soda, cinnamon, nutmeg, ginger, and salt. Whisking ensures the spices are evenly distributed throughout the flour mixture.
Step 3: Mix Wet Ingredients: In a separate bowl, combine the sugar and vegetable oil. Beat in the eggs one at a time, then stir in the vanilla extract. This creates a smooth and emulsified base for the cake batter.
Step 4: Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can lead to a tough cake.
Step 5: Add Carrots, Nuts, and Raisins: Fold in the grated carrots, walnuts or pecans (if using), and raisins (if using). Ensure the ingredients are evenly distributed throughout the batter.
Step 6: Bake the Cake: Pour the batter into the prepared pan(s) and bake for 30-35 minutes for round pans, or 35-40 minutes for a 9x13 inch pan, or until a wooden skewer inserted into the center comes out clean.
Step 7: Cool the Cake: Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely. Cooling prevents the cake from sticking and allows it to set properly.
Step 8: Prepare the Frosting: While the cake is cooling, prepare the cream cheese frosting. In a large bowl, beat together the cream cheese and butter until smooth and creamy.
Step 9: Add Sugar and Vanilla: Gradually add the powdered sugar, beating until smooth. Stir in the vanilla extract and milk or cream (if using) until the desired consistency is reached.
Step 10: Frost the Cake: Once the cake is completely cool, frost the top and sides with the cream cheese frosting. Decorate as desired.
Optional Tips: For a richer flavor, toast the walnuts or pecans before adding them to the batter. To add a tropical twist, substitute 1/2 cup of crushed pineapple for 1/2 cup of the grated carrots. A dash of lemon zest in the frosting brightens the flavor.
