Preheat oven to 425°F Oil a large baking sheet; set aside.
Whisk together first five ingredients until very smooth. Add remaining ingredients, and stir to combine (be sure to mix in thoroughly the baking soda and salt--you may want to stir these into the flour first).
Drop batter by large spoonfuls onto prepared baking sheet. Bake for about 8 minutes, or until tops just begin to crack. Remove sheet from oven, and wait 10 minutes before transferring cookies to a plate or wire rack.
