Best Double Chocolate Chip cookie recipe

There is a method to my madness I promise.I had an idea for a valentines treat for my kiddos which required a chocolate cookies. **Post for that is below** I haven't made many double chocolate chip cookies before so I decided to seek out the perfect recipe. First I looked in my Williams-Sanoma desserts cookbook and then I looked through other recipes I had. I came up with two VERY different recipes I wanted to put against each other. One uses real chocolate and one uses cocoa powder. One uses baking powder and one uses baking soda. One uses butter and the other uses butter and shortening. After making the two I thought they both were tasty so I needed other opinions.

From the cookie poll post the cookie on the left was the cookie I came up with and the cookie on the right was the Williams-Sonoma recipe. I had a few people taste both and while they said both were amazing the winner for taste was the Williams-Sanoma! Even though my cookie looked more appetizing 6 of 8 preferred the cook book one so here we go! I think that I will post my recipe later in the week as well in case any of you want to try it.

Williams-Sanoma Double Chocolate Chip Cookie


1 oz unsweetened chocolate, chopped

1/4 teaspoon salt
