These biscotti are bursting with flavor from layers of chocolate and toasted almonds! They always garner high praise and are easier to make than you’d think. I always turn to these biscotti to add an extra special touch to my holiday cookie tray.
Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.
Combine the butter with 1/2 cup of the chocolate chips in a small microwave-safe bowl. Microwave in 20-second increments, stirring until smooth and melted. Set aside to cool.
Place the eggs, sugar, salt, baking soda, baking powder, vanilla and instant coffee in the bowl of a stand mixer and beat with the paddle attachment on medium speed until pale and thickened, about 4 minutes.
Meanwhile, whisk together the flour and cocoa in a medium bowl and set aside.
Stop the mixer and add the warm melted chocolate and butter. Mix on medium speed until smooth and combined. Add the dry ingredients and mix on low speed until combined. With the mixer running on low speed, mix in the almonds and another 1/2 cup of the chocolate chips until combined.
Dip your hands in cold water to make the dough easier to handle. Divide and shape the dough into two logs; then flatten each to 12 inches long, 2 inches wide and 1 inch tall. Place the logs on the prepared baking sheet.
Bake until the logs are firm to the touch and sound hollow when tapped, 35 to 40 minutes. Remove from the oven but keep the oven on. Let the logs cool on the baking sheet for 20 minutes, then remove to a cutting board and slice crosswise with a serrated knife 3/4 inch thick. You should have about 24 biscotti.
Return the biscotti to the parchment-lined baking sheet, standing each up (with its longest skinny side down). Bake until the centers feel firm, 20 to 25 minutes. Remove from the oven and let cool completely on the baking sheet, then lay the biscotti on their sides.
Microwave the remaining 1/2 cup chocolate chips in a microwave-safe bowl in 15- to 20-second increments, stirring until smooth and melted. Transfer to a pastry bag (or heavy-duty sandwich bag and snip off a tiny tip); drizzle the chocolate over the cooled biscotti. Enjoy immediately or let set before serving or storing. You can store the biscotti in an airtight container at room temperature for up to 1 week.
