To prepare a Vincents pistachio dark chocolate chip cookies recipe, first you need to prepare your ingredients. First, you'll need your flour, baking powder, sugar, cocoa, and salt. Then, add your dry ingredients to the wet ingredients and mix until everything is combined. Now, it's time to make the chocolate chips. You can use any chocolate you like, but I like to use semi-sweet chocolate because it is richer in flavor. I used Ghirardelli chocolate and it was delicious. If you don't like chocolate, use regular chocolate.
