Preheat the oven to 350F.
Spray two 8" baking pans with cooking spray for baking.
In a large bowl, mix the eggs, olive oils, vanilla, Limoncello and the zests with a whisk until well combined.
Add the sugar, flour, salt and the Lievito degli Angeli and mix well.
Be sure to scrape the bottom of the bowl to better combine all the ingredients.
Pour the batter into the 8" baking pans.
Bake for 45-50 mins., or until a toothpick inserted in the center of the cake comes out dry and clean.
After the cakes have cooled, sprinkle with powdered sugar.
