“When I was growing up, biscotti was a hard sell,” says Carla Lalli Music. “Compared with all the other holiday cookies, the rock-hard one that you dipped in licorice-flavored liqueur was grouped under Things Adults Like That Make No Sense. Now that I’m grown, though, I’ve embraced biscotti as the anti-gooey-chewy cookie that can be packed with my preferred dessert flavors: coffee, chocolate, and nuts. Mine come out crisp but tender, and they’re sturdy enough to dunk in amaro, bourbon, or cold milk—because even in adulthood, I don’t understand sambuca.” An extra egg yolk and plenty of butter help these biscotti stay tender even after being baked twice.

Recipe information

  • Yield

    Makes about 22

Ingredients

⅔ cup blanched hazelnuts
3 large eggs
2 Tbsp. instant espresso powder or instant coffee powder
2 cups (250 g) all-purpose flour
2 tsp. baking powder
1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt
½ cup (1 stick) unsalted butter, room temperature
1 cup (200 g) sugar, plus more for sprinkling
2 tsp. coffee extract or vanilla extract
3 oz. coffee-flavored chocolate or semisweet chocolate, coarsely chopped

Preparation

  1. Step 1

    Place racks in upper and lower thirds of oven; preheat to 350°. Toast hazelnuts on a rimmed baking sheet, tossing once, until golden brown, 8–10 minutes. Let cool, then very coarsely chop. Reduce oven heat to 325°.

    Step 2

    Separate yolk from 1 egg over a small bowl to catch egg white. Place yolk in another small bowl. Set egg white aside for brushing dough. Crack remaining 2 eggs into bowl with yolk. Add espresso powder and beat with a fork to combine and dissolve.

    Step 3

    Whisk flour, baking powder, and salt in a medium bowl. Using an electric mixer on medium speed, beat butter and 1 cup (200 g) sugar until light and creamy, about 2 minutes. Scrape down sides of bowl, then add egg yolk mixture and coffee extract; beat just to combine. Scrape down sides of bowl and beat until smooth. Add dry ingredients and mix on low speed to combine. Add hazelnuts and chocolate and mix just to evenly distribute. Divide dough evenly between 2 parchment-lined baking sheets. Run your hands under cold water, then shape each dough mound into a 5" square about 1" thick. Beat reserved egg white with a fork until foamy and brush over loaves (you won’t need all of it). Sprinkle very generously with sugar.

    Step 4

    Bake loaves, rotating baking sheets top to bottom and front to back halfway through, until firm in the center and starting to crisp at the edges, 30–35 minutes. (They will spread quite a bit as they bake.) Transfer baking sheets to wire racks; let loaves cool 15 minutes.

    Step 5

    Working one at a time, carefully transfer loaves to a cutting board. Using a serrated knife, slice ½" thick. Arrange biscotti cut side down on baking sheets and bake, rotating baking sheets top to bottom and front to back halfway through, until dry and crisp, 30–35 minutes. Transfer baking sheets back to racks and let biscotti cool.

    Do ahead: Biscotti can be baked 1 week ahead. Store airtight at room temperature.
