try this: chocolate white chocolate chuck cookies

We were watching Gracie's favorite tv show, Barefoot Contessa (Yes, her favorite show is a cooking show on Food Network. And, yes, she is four.) She made these cookies and Gracie was begging me to make them. Being the fantastic mom that I am I said, "Sure! I'll make chocolate cookies if I must. For the kids."
These cookies. Oh, these cookies. These cookies are SO YUMMY!!! The texture is absolutely perfect – they're like cookies you would order in a coffee chop. They're huge — I only put 8 on a cookie sheet — which makes them an extra special treat!!

Chocolate White Chocolate Chunk Cookies

1/2 pound unsalted butter, room temperature
1 cup light brown sugar, packed
1 cup granulated sugar
2 teaspoons pure vanilla extract
2 extra-large eggs, room temperature
2/3 cup good unsweetened cocoa
2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon kosher salt I would use regular salt – I don't like Kosher salt in baking
1 1/2 pounds good white chocolate, coarsely chopped I used a 12oz package of white chocolate chips and there were PLENTY of chips.

Preheat oven at 350.
Cream the butter and two sugars until light and fluffy in the bowl of an electric mixer fitted with the paddle attachment. Add the vanilla, then the eggs, one at a time, and mix well. Add the cocoa and mix again. Sift the flour, baking soda and salt and add the chocolate with the mixer on low speed until just combined. Fold in the chopped white chocolate.
Drop the dough on a baking sheet lined with parchment paper, using a 1 3/4-inch ice cream scoop or rounded tablespoon. Dampen your hands and flatten the dough slightly. Bake for exactly 15-minutes (the cookies will seem underdone). Remove from oven and let cool slightly on the pan, then transfer to a wire rack to cool completely.
