8 ounces good quality bittersweet chocolate , 60%-72%(chopped or in chips) 

3 Tablespoons (1 1/2 ounces) butter

1 cup sugar

3 large eggs

1 teaspoon espresso powder 

1 teaspoon vanilla

1 cup all-purpose flour

1/4 teaspoon baking powder

1/4 teaspoons salt

1 cup chocolate chips 

1 cup chopped walnuts

3/4 cup golden raisins

In a double boiler, or in the microwave, gently melt together the chocolate and butter.  To avoid heating the chocolate too much and possibly burning it, the best method is to heat till the butter is melted and the chocolate has partially melted, then remove from the heat.  Stir until all the chocolate melts.

In a separate bowl, beat together the sugar and eggs till they’re thoroughly combined.  You don’t need a mixer, just do it in a medium sized bowl with a wooden spoon.   Add the melted chocolate mixture, then stir in the remaining ingredients, including the chocolate chips, walnuts and raisins, if you’

re using them.
