In another bowl beat up eggs until they are frothy, and then add to those eggs the sugar, vanilla extract, and vegetable oil mixing these ingredients together (these are our wet ingredients). Then slowly pour the dry ingredients over the liquid ingredients, and combine these two together in order to make the batter. Finally add the shredded zucchini, and chopped walnuts folding them into the batter.
