Add the eggs, and mix until they have fully incorporated to the batter.
Add the shredded carrots, ginger, vanilla extract, and pineapple. Mix well
Once all the wet ingredients are incorporated, sift the dry ingredients into the batter, and fold until it is well combined.
Fold in the chopped pecans, and mix until they are fully incorporated. Do not overmix.
Pour into the 3 prepared pans and bake in the center rack of the oven for about 15 to 20 minutes.
Once they are out of the oven, let them cool down at room temperature then transfer them to a cooling rack. Let them chill thorowgly before frosting the cakes.
