Preheat oven to 375 degrees

Mix sugars, butter, vanilla and egg in a large bowl.

In a separate bowl, combine the dry ingredients.

Add the dry ingredients to the sugar/butter mixture, mixing just until combined.

Add the chocolate chips and mix to combine.

The dough will be quite stiff. Let it sit for 10-15 minutes before dropping by rounded tablespoonfuls onto an ungreased cookie sheet.

If the dough seems too stiff, mix in a tablespoon of water.

Bake for 8 to 10 minutes or until lightly browned (the centers will be soft)

Cool slightly, remove from cookie sheets and cool on a wire rack.
