Chocolate White Chocolate Chunk Cookies

1/2 lb butter at room temperature
1 cup brown sugar, packed
1 cup granulated sugar
2 t vanilla
2 eggs
2/3 cup cocoa
2 cups flour
1 teaspoon baking soda
1 teaspoon salt
1 1/2 pounds white chocolate, coarsely chopped

Preheat the oven to 350 degrees. Cream the butter and both sugars until light and fluffy. Add the vanilla, then the eggs, 1 at a time, and mix well. Add the cocoa and mix again. Sift together the flour, baking soda, and salt and add to the chocolate with the mixer on low speed until just combined. Fold in the chopped white chocolate. Drop the dough on a baking with a rounded tablespoon. Dampen your hands and flatten the dough slightly. Bake for exactly 15 minutes (the cookies will seem underdone). Remove from the oven and let cool slightly on the pan, then transfer to a wire rack to cool completely. These are EXCELLENT for making ice cream sandwiches also! Makes about 36 cookies.

* I halved the recipe and it made about 16 cookies and they turned out PERFECT! I also only had about 4 oz of white chocolate bars so I put in milk chocolate chips too and it was delicious.
