See the recipe card at the end of the post for the full ingredients list and instructions.

Ingredients

  • Flour. All-purpose flour gives the biscotti dough structure and strength.
  • Cocoa Powder. A good-quality Dutch-processed cocoa powder adds a rich chocolate flavor and deep color.
  • Sugar. Granulated sugar sweetens the biscotti.
  • Baking Powder. Leavening agent.
  • Salt. Balances the sweetness and enhances the flavor of the chocolate.
  • Eggs. Binds the dough together to give the cookies structure.
  • Butter. Adds a rich buttery flavor, as well as makes the biscotti crisp as they bake.
  • Vanilla Extract. Flavor.
  • Chocolate Chips. I added mini chocolate chips to the dough for extra chocolate flavor. And the melted swirls of chocolate spread onto the sides of the biscotti make these irresistible.

Instructions

Make and chill the dough.

  • In a bowl, combine the flour, cocoa powder, sugar, baking powder and salt.
  • Add the 3 beaten eggs, melted butter, and vanilla extract, and stir everything together into a soft, sticky dough. Let cool for 10 minutes, then stir in the mini chocolate chips.
  • Cover the bowl and chill the dough in the refrigerator for 3-4 hours, until well chilled.
  • Dry ingredients whisked together in a bowl.
  • A bowl of chocolate batter for making chocolate biscotti.

TIP: Make sure you leave about 4 inches between each portion of dough on the baking sheet, since they will spread out as they bake. Use two baking sheets if you need more space.

Shape and bake the dough (first bake).

  • Preheat the oven to 350 F, and line a large baking sheet (or two medium baking sheets) with parchment baking paper.
  • Divide the chilled dough into three portions (about 10 ounces each), dusting each portion with a little flour to keep the dough from sticking to your hands. Roll or press each portion of dough out into a rectangular-shaped log, measuring about 3×8 inches and about 3/4 inch thick.
  • Whisk up the last remaining egg, and lightly brush the top of the dough with the beaten egg.
  • Bake the biscotti on the center oven rack for 20-22 minutes until set, but still soft in the middle. Remove from the oven, and let cool for exactly 10 minutes on the baking sheet.
  • Chocolate biscotti dough shaped into slabs on a baking sheet.
  • Once baked slabs of chocolate biscotti on a baking sheet.

TIP: Be sure to reduce the oven temperature to 325 F for the second bake.

Cut and bake the biscotti again (second bake).

  • Use a large spatula or cake lifter to carefully lift the slabs of biscotti onto a cutting board. Use a sharp knife (I find that a chef’s knife works best) to slice the slabs into individual biscotti about 3/4 – 1 inch thick. Gently place the biscotti back onto the baking sheet, turned on their side with the cut side facing up.
  • Bake the biscotti for 10 minutes. Turn the biscotti over, so the other cut side is facing up, and bake for 10 more minutes. Cool completely.
  • Make sure the biscotti is completely cooled and hardened before storing it in an airtight container.
  • Once baked chocolate biscotti being cut into pieces.
  • Chocolate biscotti arranged on a baking sheet for the second bake.

Add some melted chocolate.

  • For the melted chocolate, melt the 1 1/4 cups chocolate chips in a double boiler until smooth. You can use a spoon or piping bag to just drizzle the chocolate over the biscotti, or dip one end in and shake off the excess. I used a spoon to spread and swirl the melted chocolate along one side of the biscotti.
  • Place on a parchment-lined baking sheet for 1-2 hours until the chocolate sets and hardens.

Frequently Asked Questions

What kind of cocoa powder did you use?

I used Rodelle Dutch-processed cocoa powder.

Can I add nuts to the biscotti dough?

Of course. Chopped walnuts, pecans or macadamia nuts would all be great in this chocolate biscotti.

Why are my biscotti not crispy?

After the second bake, if your biscotti aren’t crisp after cooling completely, then they may be slightly under-baked. You can return them to the oven for a few minutes to finish drying out.

Why does my biscotti crumble when I cut it?

If you cut the biscotti while it’s too hot, it can crumble when you cut it. If it cools for too long, it can become hard and break when you cut it. Be sure to cool the biscotti after the first bake for the time stated in the recipe, no more and no less.

Do biscotti harden as they cool?

Yes, after the second bake, as your chocolate biscotti cools off, they will finish hardening and drying out.
