Essential Chocolate Chip Cookie

These cookies really should be called melt in your mouth chocolate chip cookies. They are just that good! I was a bit nervous before baking them because they use a tablespoon of vinegar but that really brings out the flavor and makes them great! (From: The King Arthur Flour Cookie Companion)
3/4 cup unsalted butter 
2/3 cup brown sugar 
2/3 cup granulated sugar 
2 tablespoons light corn syrup 
1 tablespoon cider vinegar or white vinegar (I used cider)
2 large eggs 
1 tablespoon vanilla extract 
1/2 teaspoon salt 
1/2 teaspoon baking powder 
1/4 teaspoon baking soda 
2 1/4 cups unbleached all-purpose flour 
3 cups semisweet chocolate chips (I used 1/2 cup white chocolate chips and 2 1/2 cups semisweet chocolate chips) 

1. Preheat the oven to 375. Lightly grease (or line with parchment) two baking sheets. 

2. In a medium-sized bowl, cream together the butter, sugars, corn syrup, and vinegar, then beat in the eggs. Beat in the vanilla, salt, baking powder, and baking sida. Stir in the flour and the chocolate chips. 

3. Drop the dough by tablespoon onto the prepared baking sheets. Bake the cookies for 10 minutes, until they are just set; the centers may still look a bit underdone. Remove them from the oven, and transfer to a rack to cool.
