I love biscotti, or cantucci. These twice-baked Italian biscuits are one of my favorite Italian treats. They are wonderfully simple, light, and totally moreish.

Inspired by my almond biscotti, chocolate dipped biscotti, and chocolate chip biscotti, today’s biscotti recipe has all the crunchysweet goodness of classic biscotti, but with a sophisticated lemon flavor.

The combination of fresh lemon juice and zest with the honey infuses the biscotti with a sensational complex flavor in every bite.

Everything is also enhanced by the delicious chopped almonds mixed into the dough for extra texture. But you are welcome to make nut-free biscotti as the recipe can be easily customized (I’ve also included some ideas for alternative mix-ins!).

These lemon biscotti are also economical and keep exceptionally well. You can double the recipe and make several dozens of these amazing Italian cookies to share with family and friends.

Recipe notes

Lemon biscotti ingredients & substitutions

Flour + baking powder: Start by mixing flour with baking powder and about 1/4 teaspoon salt for flavor.

Eggs: You need one egg and an egg yolk for the biscotti dough. But if wish to give biscotti as a homemade gift, I recommend brushing the logs with an egg wash for beautiful shiny finish (I also love a sprinkle of these white pearl sugar!).

Sugar: I used unrefined caster sugar as it incorporates well into batter (here in the UK caster sugar has finer grains than regular sugar), but also powdered sugar works well. However, regular sugar (granulated sugar) is fine too if it’s all you have on hand.

Almonds: I added some toasted chopped almonds for texture. However, you can load them with whatever nuts you have in hand (pistachios, hazelnuts, walnuts, pecans), delicious dried fruit (sultanas or cranberries) or you’re welcome to skip the nuts to make simple nut-free lemon biscotti. I’ve also tested this lemon biscotti recipe using white chocolate chips instead of almonds, and it was delicious.

Butter: This biscotti recipe only calls for 2 Tbsp of butter and strikes the perfect balance to make perfectly crunchy biscotti, not too hard.

Flavor: Apart from honey, vanilla, the recipe uses plenty of lemon zest and juice to maximise the flavor. I prefer the scent of fresh lemons, but you can use about 1/2 teaspoon of lemon extract if more convenient.

Baking powder: 1 tsp of baking powder is enough to keep the right balance between lightness and their typical dense texture. I don’t recommend using self-raising flour for this biscotti recipe.

Top tips

  • Don’t over-bake them or they will break your teeth!
  • The dough is a bit sticky, but don’t add extra flour.
  • Wet your hands to avoid the dough sticking to them.
  • Make sure the two logs have the same size and shape.
  • Allow room between the two logs – they spread in the oven.
  • Brush the logs with beaten egg for a beautiful finish.
  • Slice the logs when they’re still warm – not hot or they will crumble!
  • Use a sharp knife for a clear cut.
  • Try to get uniform sized biscotti.

  • 1 medium-sized egg
  • 1 egg yolk
  • ½ cup (100 grams) sugar
  • 2 tablespoons (30 grams) butter, melted
  • 1 teaspoon vanilla extract
  • 1 tablespoon lemon zest (from a large lemon)
  • 1 tablespoon lemon juice
  • 3 tablespoon honey
  • 2 cups + 1 Tbsp (260 grams) all-purpose flour
  • 1 teaspoon baking powder
  • ¼ teaspoon fine salt
  • 100 grams toasted almonds, slivered or chopped (optional)


  • 1 egg (to brush the biscotti logs)
  • 3 tablespoons pearl sugar


  • Preheat the oven to 350°F (177°C) and line a baking sheet with parchment paper.
  • Whisk the flour and the baking powder in a bowl. Set aside.
  • Using a stand mixer fitted with a whisk attachment or an electric beater (or a whisk) beat 1 egg, egg yolk, and the sugar on medium-high speed until pale and fluffy, about 1 or 2 minutes.
  • Reduce the speed, and add gradually the melted butter, then vanilla, honey, lemon juice and zest. Mix until combined.
  • With the motor running, add the flour in a few steps, not all in one go. Add the almonds if using them, and mix until just combined. Scrape down the sides and bottom of the bowl as needed during this step.
  • Remove the dough from the bowl, transfer onto a surface, and shape it into two equal logs (possibly same size and shape). If the dough is sticky, don't add any flour, simply wet your hands to handle it.
  • Place the two logs onto the prepared baking sheet well apart from each other (they will spread once in the oven), press gently with your hands flattening them a little bit. For a shiny finish, I recommend brushing the logs with a beaten egg (aka egg wash) and sprinkle with pearl sugar if desired.
  • Bake in the preheated oven for 30 minutes until firm and golden.
  • Remove the baking sheet from the oven, place it on a rack, let cool down for about 10 minutes and reduce the oven temperature to 250℉-120℃.
  • Transfer the logs on a cutting board and using a sharp knife, with a sewing motion, slice the logs diagonally into about ½ inch thick slices (or thicker, if desired).
  • Return the biscotti slices to the baking sheet, cut side up, and bake them again for 10 minutes per side, total 20 minutes.
  • Let the lemon biscotti cool. They keep well in airtight containers or metal tin for about 10 days.


How to store lemon biscotti? Usually biscotti keep well for about 10 days, maximum 2 weeks,  stored in an airtight container (metal tin or a glass jar are my favorite containers for biscotti).
