1/3 cup butter, softened
2/3 cup white sugar
1 teaspoon vanilla extract
1 3/4 cups all-purpose fl our
1/3 cup unsweetened cocoa powder
2 teaspoons baking powder
1/2 cup miniature semisweet chocolate chips
1/4 cup chopped walnuts
1 egg yolk, beaten
1 tablespoon water
Preheat oven to 375°F (190°C). Grease baking sheets, or line with parchment paper.
In a large bowl, cream together the butter and sugar until smooth. Beat in the eggs one at
a time, then stir in the vanilla. Combine the fl our, cocoa and baking powder; stir into the
creamed mixture until well blended. Dough will be stiff, so mix in the last bit by hand. Mix
in the chocolate chips and walnuts.
Divide dough into two equal parts. Shape into 9x2x1-inch loaves. Place onto baking sheet 4
inches apart. Brush with mixture of water and yolk.
Bake for 20 to 25 minutes in the preheated oven, or until firm. Cool on baking sheet for
Using a serrated knife, slice the loaves diagonally into 1-inch slices. Return the slices to the
baking sheet, placing them on their sides. Bake for 10 to 15 minutes on each side, or until
dry. Cool completely and store in an airtight container.
