Triple Chocolate Biscotti

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 milk chocolate chips
12 oz semi-sweet chocolate
Preheat oven to 400F. Cream together butter and sugar. Beat in eggs, one at a time, until smooth then add vanilla extract. Sift together all of the dry ingredients and stir into the egg mixture. Add chocolate chips and stir to combine.
Shape the dough into short loaves (about 6-inches long) and bake for 25 minutes. Remove from oven and let cool completely. Cut each loaf into 1-inch diagonal slices. Reduce heat in your oven 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 in a microwave or double boiler, and drizzle over the cooled biscotti.
