50 to 60 cookies
Use a good-quality cocoa powder. You can use natural or Dutch-process for these, whichever one you like. Just remember that the chocolate flavor of the finished cookies is dependent on the quality of cocoa powder you use. So it's worth using a decent one. I used Valrhona. See notes below on ingredients.
If you like extra-crisp biscotti, you can flip each one over midway during the second baking, in step #6. I sometimes smear one side of the cookies with melted dark chocolate. When dipped in a warm espresso, I can't imagine anything better.
For the biscotti
2 cups (280g) flour
3/4 cups (75g) top-quality cocoa powder
1 teaspoon baking soda
1/4 teaspoon salt
3 large eggs, at room temperature
1 cup (200g) sugar
1 teaspoon vanilla extract
1/2 teaspoon almond extract
1 cup (125g) almonds, toasted and very coarsely-chopped
3/4 cups (120g) chocolate chips
For the glaze
1 large egg
2 tablespoons coarse or crystal sugar (see Notes)
1. Preheat the oven to 350F (180C) degrees.
2. In a small bowl, sift together the flour, cocoa powder, baking soda, and salt.
3. In a large bowl, beat together the 3 eggs, sugar, and vanilla & almond extracts. Gradually stir in the dry ingredients, then mix in the nuts and the chocolate chips until the dough holds together.
4. Line a baking sheet with parchment paper or a silicone mat. Divide the dough in half. On a lightly floured surface, roll the dough into two logs the length of the baking sheet. Transfer the logs onto the baking sheet, evenly spaced apart.
( I eliminated this next step- the egg and the sugar!)
Beat the remaining egg and brush the tops of the logs liberally with the egg. (You won't use it all). Sprinkle the tops with the coarse or crystal sugar and bake for 25 minutes, until the dough feels firm to the touch.
6. Remove the cookie dough from the oven and cool 15 minutes. On a cutting board, use a serrated bread knife to diagonally cut the cookies into 1/2-inches slices. Lay the cookies cut side down on baking sheets and return to the oven for 20 to 30 minutes, turning the baking sheet midway during baking, until the cookies feel mostly firm.
Once baked, cool the cookies completely then store in an airtight container for up to two weeks. If you wish, the cookies can be half-dipped in melted chocolate, then cooled until the chocolate hardens.
I chose to drizzle a little white and a little dark chocolate on my biscotti!
