To Die for Chocolate Biscotti

• 12 cup unsalted butter, at room temperature
• 34 cup granulated sugar
• 2 large eggs
• 1 large egg yolk
• 1 teaspoon pure vanilla extract
• 1 34 cups all-purpose flour
• 1 teaspoon baking powder
• 14 teaspoon salt
• 12 cup Dutch-processed cocoa powder
• 34 cup Nestle semi-sweet and white chocolate swirled chocolate morsels (or any other mix of white and milk chocolate chips)
• dipping chocolate

1. Preheat oven to 350 degrees F (177 degrees C) and place rack in center of oven.
2. Line a baking sheet with parchment paper, and set aside.
3. In the bowl of your electric mixer (or with a hand mixer), cream the butter and sugar until light and fluffy (2-3 minutes).
4. Add the eggs and egg yolk, one at a time, mixing well after each addition.
5. Beat in the vanilla extract.
6. In a separate bowl, whisk together the flour, baking powder, salt, and cocoa powder.
7. Add to the butter mixture and beat until incorporated.
8. Stir in the chocolate/white chocolate chips.
9. Transfer the dough to a floured surface.
10. Form into a log 10 inches long.
11. Do this by rolling the dough back and forth into a cylinder shape with floured hands.
12. Transfer the log to the baking sheet, and pat to even the shape.
13. Bake until firm to the touch, about 25 - 30 minutes.
14. Remove from the oven, place on a wire rack, and let cool for about 10 minutes.
15. Using a long spatula transfer the logs to a cutting board.
16. Using a serrated knife, cut the logs into slices about 2/3 inch thick.
17. Arrange the slices on the baking sheet, cut side down, and bake about 8 - 10 minutes.
18. Turn the slices over and bake until crisp and dry, about 8 - 10 minutes longer.
19. Remove from oven and let cool on wire rack.
20. Optional Steps: Follow melting directions on dipping chocolate (or make your own), and use spatula/piping bag to drizzle chocolate over the tops of the biscotti.
