Cookies

2C unbleached all purpose flour
2C packed light brown sugar
1tsp baking soda
1/2C(1 stick) cold unsalted butter, cut into pieces
1 large egg
1tsp vanilla extract
1C sour cream
2TBS whole milk
1 1/2C(9 oz) semi-sweet chocolate chips

Place rack in middle of oven and preheat to 325 degrees. Line baking sheets with parchment paper and butter.

In electric mixer on low speed mix flour, sugar, and baking soda to blend. Add butter and mix until butter pieces are size of peas, about 2 minutes. Stop mixer and scrape sides. Mix in eggs and vanilla. Batter will look dry. Mix in sour cream and milk until batter looks moistened, there will probably still be lumps of butter. Mix in chocolate chips.

Drop heaping tablespoons onto prepared cookie sheet at least 2 and a half inches apart. Bake one sheet at a time until tops are still soft but firm, edges are lightly browned and crisp. You want a toothpick stuck in center to come out clean, it's about 17 minutes.

Cool on sheet about 10 minutes the transfer to wire rack to cool completely.

Filling
1/2C heavy cream
2TBS unsalted butter, cut into pieces
1 1/3C(8 oz) semi-sweet chocolate chips

in medium saucepan heat cream and butter over low heat until tiny bubbles form on surface and butter is melted. Remove from heat and add chocolate chips, let sit to soften for 30 seconds. Whisk filling
until smooth and chips are melted.

Pour filling into a bowl and let sit at room temp until thickened, about 45 minutes. You can also do this in the fridge if you are in a rush for about 20 minutes.

To fill the cookies turn half bottom side up. Leave a bit of a border and spread filling over bottoms. You do not want it to be runny. If it is cool a little longer. Top cookies bottom side down.

You can wrap them in plastic and store at room temp or in the fridge for about 3 days. Makes 12.

These cookies are amazing. They are very rich. So rich that you might not be able to finish and entire one.

The entire book is wonderful. Highly recommended.
