Preheat oven to 375.  In a large bowl, whisk dry ingredients.  In another bowl, whisk wet ingredients until blended.  Combine the two mixtures; stir just until moistened.  Fold in chocolate chips.  Fill greased or papered muffin cups.  Bake 17-20 minutes.  Cool 5 minutes before removing to wire rack.
