In a large bowl of a stand mixer, beat together the butter, oil, sugar, powdered sugar, vanilla and eggs until creamed and combined, about 2 minutes. Add in the baking soda, tarter, salt and flour and gently mix until a soft dough forms. Chill in the fridge for at LEAST 2 hours.

Preheat oven to 350 degrees F. Line 2 baking sheets with silicone baking mats or spray the sheets lightly with cooking spray. Using a cookie dough scoop, portion out rounded Tablespoon-sized balls of dough and roll in the additional white sugar to coat. Place 2" apart on the prepared sheets.

Bake for approx. 9-11 minutes, rotating pans halfway through baking time to ensure even baking or until golden brown. Do not over-bake. Cool on the cookie sheets completely before serving. Ice if desired.
