If there is a word that should always come before chocolate it is the word double! You will love these Double Chocolate Biscotti, they are delightful with coffee or tea.
To measure the flour, spoon it lightly into the measuring cups and level with a knife. In a medium bowl combine the flour, sugar, cocoa, chocolate chips, baking powder, baking soda, and salt. Whisk together.
In a large bowl, whisk together the vanilla extract and eggs. Add the flour mixture to egg mixture and stir to combine. Divide the dough in half and pat out two 12 inch loaves, about ½ inch thick, on a baking sheet coated with cooking spray (I used parchment paper).
Bake for 22 minutes. Remove from oven and cool on a wire rack for 10 minutes. Cut each loaf diagonally into ½ inch slices. Stand them back up on the baking sheet and return to the oven to bake for an additional 15 minutes. Remove from oven and let cool on a wire rack.
Store in an airtight container.
Notes
I sometimes substitute ¼ cup of whole wheat flour for ¼ cup of the all-purpose flour.
