Chocolate Chocolate Chip Cookies

I have been obsessing about making the perfect chocolate chip cookie, here's my spin on a chocolate chocolate chip cookie, I think they are perfect! Enjoy! ~Fran

1 C butter, softened
2 ounces unsweetened chocolate, melted
1 C brown sugar
1/2 C granulated sugar
1 tsp. vanilla extract
1 egg
2 1/2 C flour
1 tsp. baking soda
1 tsp. salt
2 TBS cocoa powder
1 C white chocolate chips
Preheat oven to 350°F. Line baking sheets with parchment paper, or grease lightly. Melt the unsweetened chocolate bar in a microwave safe bowl for 20 seconds about 3 times or until almost melted, (be careful the bowl will be hot!), stir until completely smooth. In a large mixing bowl, whip the butter until fluffy on medium speed. Add the melted chocolate, mix on low speed until combined. Add the granulated sugar, brown sugar and vanilla and beat until smooth, add the egg and beat on medium speed until fluffy about 2 minutes. Set aside. In a medium bowl, sift together the flour, baking soda, salt and cocoa powder. With the mixer on medium low, slowly add the flour mixture and mix until completely incorporated. Fold in the white chocolate chips. With a medium scoop (I use the pampered chef medium size-about 1 1/2 TBS) place the cookie dough 2" apart on the baking sheet. Bake 13 minutes, let set for 2 minutes on the baking sheet before transferring to a cooling rack, let cool 10 minutes before storing in an air tight container. Makes 2 1/2 dozen.
