Homemade Double Chocolate Biscotti with Sea Salt: Your New Favorite Twice-Baked Treat
Prepare to fall in love with these incredibly crisp and rich **double chocolate biscotti cookies**, elegantly dipped in decadent dark chocolate and finished with a delicate sprinkle of flaky sea salt. These traditional Italian “twice-baked” marvels are designed to convert even the most staunch biscotti skeptics into enthusiastic devotees. Forget everything you thought you knew about biscotti; this homemade version promises a truly sublime experience that will elevate your coffee breaks and dessert platters alike.
Let me start with a small, yet significant, confession: for the longest time, I viewed biscotti as the overlooked stepchild of the cookie family. Often hard, sometimes dry, and typically less flamboyant than their chewy, gooey, or frosting-laden counterparts, store-bought biscotti rarely sparked joy. I imagined them harboring a “second child syndrome,” feeling perpetually overshadowed by their more popular cookie siblings. After all, who ever hears someone declare biscotti as their absolute favorite cookie?
But then, a revelation occurred. It turns out, when you bake biscotti from scratch, infusing them with generous amounts of cocoa, enriching them with a deep, dark chocolate coating, and then accentuating their flavor with a sprinkle of delicate sea salt – they transform. They transcend their humble reputation, becoming something infinitely more delicious and sophisticated than any mass-produced version you might have encountered. This recipe is a game-changer, demonstrating the true potential of these Italian classics when made with care and high-quality ingredients.
The Art of the Twice-Baked Cookie: A Brief History of Biscotti
Biscotti, whose name literally translates to “twice-baked” in Italian, boasts a rich history rooted in practicality. Originating in Prato, Tuscany, these cookies were developed for their incredible shelf life, making them ideal for travelers and sailors. The double-baking process removes almost all moisture, preventing spoilage and creating their signature crisp texture. Traditionally, they were served with Vin Santo, a Tuscan dessert wine, into which they were dipped to soften before eating. While the original recipes often featured almonds, modern variations like this **double chocolate biscotti** have evolved to include a wide array of flavors, nuts, and delicious coatings, making them a versatile and beloved treat worldwide.
This particular recipe draws inspiration from the legendary Dorie Greenspan, a culinary icon renowned for her expertise in baking. Her meticulous approach and understanding of flavors ensure that this **homemade biscotti recipe** delivers an exceptional result every single time. If you’re familiar with her work, you know you’re in for a treat.
Demystifying the Biscotti Baking Process
Despite their gourmet appearance, biscotti are surprisingly straightforward to make, and the dough comes together in a flash. The entire process, from mixing to the final decadent dip, is an enjoyable culinary journey. Here’s a breakdown of the steps that make these cookies so unique and delicious:
The First Bake: Forming the Flavorful Logs
The initial stage involves creating the dough, which is dense and rich with cocoa and espresso powder. This dough is then shaped into rectangular logs. The key here is to ensure the logs are uniform in thickness to promote even baking. These logs undergo their first bake, typically for about 20-25 minutes, until they are firm to the touch but not yet fully crisp. This primary bake sets the shape and structure of the biscotti, preparing them for their signature second bake.
Cooling, Slicing, and the Second Bake for Ultimate Crispness
Once the logs emerge from the oven, they need to cool sufficiently on the baking sheet. This cooling period is crucial, as it allows the logs to firm up, making them easier to slice cleanly without crumbling. After cooling, the logs are carefully sliced into the classic biscotti shape using a serrated knife. This step reveals the interior texture and prepares each piece for its final transformation. The sliced cookies are then returned to the oven for their second bake. This secondary baking phase is where the magic happens, drying out the cookies further and imparting that unmistakable crisp, sturdy texture that biscotti are famous for. They will turn golden brown around the edges and become perfectly firm.
The Decadent Finale: Dark Chocolate and Flaky Sea Salt
While classic biscotti are delightful on their own, this recipe takes them to an unparalleled level of indulgence. Once the **crisp biscotti** have cooled completely after their second bake, they are individually dipped in luscious melted dark chocolate. This adds a layer of intense chocolate flavor and a beautiful sheen. But the indulgence doesn’t stop there. Before the chocolate sets, a generous sprinkle of flaky sea salt is added. The interplay between the bitter dark chocolate, the rich cocoa in the cookie, and the subtle crunch and briny notes of the sea salt creates an absolutely heavenly flavor profile that truly makes these **dark chocolate biscotti** exceptional. It’s this thoughtful addition that elevates them “over the top,” transforming a simple cookie into a sophisticated treat.
Why These Double Chocolate Biscotti Will Become Your Go-To Recipe
These **homemade biscotti** aren’t just delicious; they are incredibly versatile and practical. Their sturdy, crisp nature makes them ideal for dipping into your favorite hot beverage, whether it’s your morning coffee, a comforting afternoon tea, or a rich espresso.

Equipment
- KitchenAid 5 Qt. Artisan Stand Mixer
- Half Sheet Pan
Ingredients
- 2 cups (240 g) unbleached all-purpose flour
- ½ cup (50 g) unsweetened cocoa powder, sifted
- 2 tablespoons instant espresso powder (I recommend Medaglia D’Oro)
- ¾ teaspoon baking soda
- ½ teaspoon baking powder
- 1 teaspoon kosher salt
- 6 tablespoons (3 oz; 85 g) unsalted butter, softened
- 1 cup (200 g) granulated sugar
- 2 large eggs, room temperature and slightly beaten
- 1 teaspoon pure vanilla extract
- 1 cup (65 g) raw sliced almonds, roughly chopped
- Granulated sugar, for dusting
For Decoration:
- 12 ounces dark chocolate or glazing chocolate, melted
- Fleur de sel or Maldon, for sprinkling
Instructions
- Preheat the oven to 350°F (176°C) with a rack in the center position. Line a half sheet pan with parchment paper and set aside.
- Combine the flour, cocoa powder, espresso powder, baking soda, baking powder, and salt in a medium bowl, whisk together, and set aside.
- In the bowl of a stand mixer, fitted with a paddle attachment, combine the butter and sugar. Beat over medium speed for 2 to 3 minutes, or until the mixture is fluffy and pale in color. Add the eggs and vanilla and continue to beat for 1 to 2 minutes, scraping down the bowl with a spatula to ensure all of the ingredients incorporate evenly.
- Reduce speed to low and slowly add the dry flour mixture, mixing until a dough just comes together. Add the almonds and mix until just incorporated. The dough will be thick and fairly sticky.
- Turn the dough onto a clean countertop and knead lightly to combine any dry ingredients that were not incorporated. Divide the dough in half using a bench scraper. Roll each piece into a 12-inch (30 cm) log and set on the lined sheet pan, leaving space between them for spreading. Flatten the logs with your palm until they are ¾-inch to 1-inch (2 cm – 2.5 cm) thick and rectangular in shape. Sprinkle the tops of the logs with granulated sugar.
- Bake for 25 minutes or until the logs are firm to the touch. Set the pan on a rack and allow the logs to cool on the baking sheet for 20 minutes. Leave the oven preheated.
- Remove the logs to a cutting board, and using a serrated knife, cut each log cross-wise into ½ to ¾-inch thick pieces. Set the cookies, cut-side down, onto the lined half sheet pan. The pieces can be placed close together, as they will not spread during this second baking.
- Bake at 350°F (176°C) for 10 minutes or until crisp. Transfer the biscotti to a wire rack to cool completely.
- Decorate: Once cookies are cool, melt the chocolate in a microwave-safe bowl in 15 to 20-second increments, stirring with a spatula between each interval. Dip the cookies lengthwise into the melted chocolate, coating halfway up the edge.
- Lay the biscotti on the parchment-lined baking sheet. Allow the chocolate to set a bit before sprinkling with flaky salt. If using glazing chocolate, the chocolate should set fairly quickly. If not, feel free to place them in the refrigerator for 5 to 10 minutes or until the chocolate is firm. Biscotti can be kept in an airtight container for up to 1 week or longer.
