Chocolate Chip Biscotti

Combine sugar and butter in a large mixing bowl using an electric mixer until they achieve a light and fluffy consistency. Gradually incorporate cocoa powder into the mixture, followed by baking powder, blending everything together for 2 minutes. Introduce eggs one at a time into the mixture, ensuring each egg is fully incorporated before adding the next. Using your hands, gently fold in flour to create a cohesive dough. Mix in white chocolate and chocolate chips into the dough, covering it with plastic wrap to chill for approximately 10 minutes.

Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a cookie sheet with butter or cooking spray to prevent cookies from sticking. Divide the dough into two equal portions and shape each portion into a 9-inch long log. Place the logs on the prepared cookie sheet, leaving about 4 inches of space between each log to allow for even baking. Gently flatten the logs slightly.

Bake the cookies in a preheated oven for 20 to 25 minutes, or until a toothpick inserted into the center of a cookie comes out clean. Remove the cookies from the oven and let them cool on the cookie sheet for 5 minutes before transferring them to a wire rack to cool completely, allowing them to set for about an hour.

Preheat your oven to 325 degrees Fahrenheit (165 degrees Celsius). Cut each cookie log into 1/2-inch wide diagonal slices. Arrange the slices on an ungreased cookie sheet, leaving space between each slice to allow for even baking. Bake the slices in a preheated oven for 9 minutes, then turn them over and bake for an additional 7 to 9 minutes.
