Kitchen Tools You’ll Need
- Mixing bowls
- Baking sheet
- Parchment paper
- Whisk
- Rubber spatula
Ingredients
- 2 ¼ cups all-purpose flour (provides structure)
- 1 cup granulated sugar (adds sweetness)
- 1 teaspoon baking powder (creates leavening)
- ¼ teaspoon salt (enhances flavor)
- Zest of 2 lemons (offers bright citrus flavor)
- 2 large eggs (binds the dough)
- 2 tablespoons fresh lemon juice (adds moisture)

- 1 cup powdered sugar (for the glaze)
- 2-3 tablespoons fresh lemon juice for glaze (adds tanginess)

How to Make Lemon Biscotti
Step 1. Begin by preheating your oven to the appropriate temperature, which prepares the environment for even baking. Line a baking sheet with parchment paper so the biscotti won’t stick during the baking process. This step ensures they can easily be removed later without any unwanted mess.
Step 2. In a mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt. The flour provides structure while the sugar contributes sweetness to the cookies. Mixing these dry ingredients well helps incorporate the baking powder uniformly, ensuring an even rise when baked.
Step 3. Next, add the lemon zest to the dry mixture. This addition will infuse your biscotti with a bright citrus flavor that complements the other ingredients beautifully. Stir the mixture to help release the oils from the zest, which enhances the overall flavor profile of the dough.
Step 4. In a separate bowl, whisk together the eggs, fresh lemon juice, and vanilla or almond extract. This step combines the wet ingredients smoothly, preparing them to be incorporated into the dry mixture without any clumps. The eggs serve as a binder, essential for the texture of your biscotti.
Step 5. Slowly pour the wet ingredients into the dry ingredients, mixing gently until a cohesive dough forms. At this point, you should be careful not to overmix; the dough should just come together without becoming tough. The texture should be slightly sticky but manageable.
Step 6. Incorporate the softened unsalted butter into the dough. This addition will enrich the biscotti, giving it a tender crumb while still maintaining that signature crunch. Mix until the butter is well integrated, and the dough has a smooth consistency without visible lumps of butter.
Step 7. Divide the dough in half and shape each half into a log about 12 inches long. Aim for an even shape to ensure uniform cooking. Place the logs on the prepared baking sheet, giving them enough space to spread slightly while baking.
Step 8. Bake the logs for 25 to 30 minutes, or until they turn lightly golden and are firm to the touch. During this time, the logs will rise and take on a pleasing texture. Let them cool on the baking sheet for about 10 minutes before moving on to the next step.
Step 9. Once slightly cooled, use a serrated knife to slice each log diagonally into ½-inch wide pieces. This diagonal cut not only looks nice but also maximizes the surface area for crisping. Be gentle during slicing to maintain the integrity of the biscotti pieces.
Step 10. Arrange the slices on the baking sheet, cut side up. This positioning allows the biscotti to bake evenly and develop that delightful crunch. If you prefer them extra crunchy, you can turn them over halfway through baking.
Step 11. Return the biscotti to the oven and bake for an additional 10 to 15 minutes, until they become golden and dry. During this time, watch for a slight hardness when you touch them. Their crispiness will enhance their final texture, making them perfect for dipping into coffee or tea.
Step 12. Allow them to cool completely on a wire rack before glazing. While cooling, you can prepare the lemon glaze by whisking the powdered sugar with 2-3 tablespoons of fresh lemon juice until smooth. The glaze adds a sweet citrus finish to the biscotti.
Step 13. Once the biscotti are cool, drizzle or dip them in the glaze. This step adds a nice finishing touch, balancing the lemony flavors. The glaze will harden slightly as it sets, giving your biscotti an appealing sheen.
Step 14. Finally, let the glazed biscotti sit for a bit to allow the glaze to set. After that, feel free to enjoy them straight away, or store them for snacking later. The final result is beautifully crisp cookies that are perfect companions for coffee or tea.

Pro Tips for Best Results
- Make sure to measure ingredients accurately for the best texture.
- Allow the dough to rest for a short time to ensure it holds its shape better.
- Slice the biscotti with a serrated knife to achieve clean edges.
- If you prefer a more intense lemon flavor, consider adding a bit more lemon zest to the dough.
- Let the biscotti cool completely before glazing to prevent the icing from melting away.
- Store in an airtight container to maintain crunchiness.
Common Mistakes to Avoid
- Not measuring flour correctly can lead to a dry dough, resulting in tough biscotti. Always use the spoon-and-level method for accuracy.
- Overbaking the logs initially can make them too dry. Keep an eye on them and rely on visual cues to determine doneness.
- Allowing the biscotti to cool too much before slicing can make them hard to cut. Aim for a balance where they’re cool yet still sliceable.
- Failing to let the glaze set can result in a sticky mess, so be patient before serving.
- Skipping the second bake can lead to softer biscotti instead of the desired crunch. Ensure to follow the full baking process.
- Not mixing well enough can leave lumps of flour or butter. Aim for a uniform dough for a consistent texture throughout.
Variations & Substitutions
For those looking to customize, consider adding chopped nuts or dried fruits for added texture. You could also experiment with other extracts if you prefer flavors like almond or lemon in a different form. Adjusting the sweetness by using less sugar can create a less sweet version, depending on your taste preferences.
Storage & Reheating
At room temperature, you can store the biscotti in an airtight container for up to a week, maintaining their crunchy texture. If you prefer, refrigerating them will extend their freshness for a couple of weeks. For longer storage, biscotti freeze well; wrap them tightly and store in a freezer bag for optimal quality. To reheat, simply place them in a preheated oven for a few minutes to restore their crunchiness.
