Sift flour with baking powder and salt, set aside. Melt 1¼ cups of the chocolate chips and the unsweetened chocolate in a double boiler or the microwave.
Beat the butter, eggs, sugar and vanilla in a medium bowl for 4 minutes at medium speed. Scrape down sides and beat 2 more minutes. Add the melted chocolate and beat one minute more. Add the sifted dry ingredients and the remaining chocolate chips and beat just until mixed. Refrigerate the batter for 15 minutes.
Preheat the oven to 325°.
Place 1 heaping tablespoon of dough per cookie on greased cookie sheet, bake for 9 minutes (don't overbake). Cool on wire rack and try not to eat them all in one sitting.
You can also add some nuts if you like, I've used pecans and macadamia and both worked very well.
