Triple Chocolate Biscotti

Ingredients

5 cups flour
1 1/2 cups cocoa powder
2 tbs baking powder
1 cup butter
2 cups sugar
6 eggs
1 tbs vanilla extract
2 cups chocolate chips
12 oz semi-sweet chocolate

Directions

Preheat oven to 400F. Cream sugar and butter. Beat in eggs, one at a time, until smooth and add vanilla extract. Sift together the dry ingredients and add to the egg mixture. Stir in chocolate chips. Shape the dough into 6 longs loaves and brush with beaten egg yolk. Bake for 25 minutes. Remove from oven and let cool completely. Cut each loaf into 1 inch slices and place back on baking sheet. Reduce heat to 350F and place slices back into the oven. Bake for another 10 minutes, then remove from the oven and cool. Melt the semi-sweet chocolate, and drizzle over the biscotti.
