Preheat oven to 350 degrees. Grease a 9 x 13-inch cake pan.
CAKE: In a large bowl, beat sugar, eggs and oil. Add flour, soda, salt, cinnamon and vanilla, beat well. Stir in carrots, nuts and raisins. Pour batter into prepared cake pan and bake for 35-45 minutes. Let cool and frost with cream cheese frosting.
CREAM CHEESE FROSTING: Mix together cream cheese, butter and powdered sugar. If too stiff add lemon juice until spreading consistency is obtained.
Pictured above: I made a 3-tier cake instead of a 9 x 13-inch cake, doubled the frosting, and decorated the top with "carrots" and the sides with chopped pecans!
