Preheat oven to 375 degrees Fahrenheit. Line baking sheets with parchment paper or silicone baking mats. Set aside.
Using a hand or stand mixer, mix all ingredients except powdered sugar in a medium bowl on low just until ingredients are well incorporated. Don't over mix.
Put powdered sugar in a small plate or shallow dish. Drop dough by rounded spoonfuls into the sugar. Coat and roll dough into 1" balls. Place on lined baking sheets.
Bake for 6-9 minutes or until bottoms are only slightly browned. Do not let bottoms get over browned or cookies won't be light and fluffy.
