Biscotti is my kind of cookie. Is there another that crunches so beautifully? I don't think so. Another that pairs so perfectly with a cup of hot tea or latte? Definitely not. I'm not a fan of soft, cakey cookies. Every cookie should have at least a little crunch if you ask me.

It's the double baking that gives the cookies that extra crunch. First, they're baked as a large piece of dough, then sliced into individual biscotti, and then given a second bake.

The word biscotto originated from the Medieval Latin word "biscoctus," meaning "twice cooked." However, today in Italy, biscotti refers to any cookie or biscuit.

😍 Why you'll love these biscotti

  1. If you love lemon, these are the biscotti for you. They have the prominent and refreshing taste of lemons, and the limoncello icing takes them to the next level.
  2. These biscotti are great for sharing. Their longer shelf life makes these good for traveling, shipping, and making ahead.
  3. You can customize the recipe to make other flavored biscotti. Try it with other liqueurs, such as amaretto, frangelico, Chambord, or cointreau.

🍋 Ingredients

Everything you need to make these limoncello biscotti.

all of the ingredients for making limoncello biscotti

Key Ingredients

  • Limoncello: Limoncello is an Italian liqueur made with a neutral-tasting alcohol, such as vodka, infused with lemon zest for an intense but pleasant, lemony flavor. You can find limoncello at your local liquor store. There's no need for anything high-end for this recipe, but if you plan to drink it as well, get something decent. Or you can try making some of your own. Homemade limoncello is a great gift and would go great with a plate of these limoncello biscotti during the holidays.
  • Lemon zest: For some extra lemon zing in the cookies.
  • Hazelnuts: These add a nutty crunch to the cookies, and hazelnut is another classic Italian ingredient that pairs really nicely with lemon.
  • Powdered sugar: This is used to make the limoncello icing. Omit if you don't want icing.

See the recipe card below for the complete list of ingredients and quantities.

Hesitant about using limoncello? Don’t worry, the flavor in the biscotti doesn’t taste like alcohol. However, you should probably enjoy the taste of lemon. And if you want a little more punch, you can make the optional limoncello icing for the complete limoncello experience. 

🍒 Substitutions & Variations

  • Alcohol-free version: If you don't want to use limoncello in your biscotti, you can substitute an equal amount of lemon juice for both the biscotti and the icing. They will have a milder flavor, so add some extra lemon zest to compensate.
  • With other nuts: Almonds and pistachios would also work well. Or you can omit nuts altogether.
  • Add dried fruit: Toss up to ½ cup of dried fruit, such as cherries or cranberries, into the batter with the hazelnuts.
  • Experiment with other flavored liqueurs: Replace the limoncello with another liqueur of your choosing. Omit the lemon zest and choose a complimentary nut or dried fruit.

🔪 Top tips

  • The dough is going to be soft at first. You want to add enough flour to keep it soft, but not sticky. So if it's sticky when shaping the dough, pat it with a little more flour until it's smooth and easy to handle.
  • When cutting the biscotti dough after the first bake, cut the cookies at a slight angle to create larger pieces with the classic look and shape.

🫙 Storage

Store completely cooled biscotti in an airtight container at room temperature. They will keep for about two weeks. Biscotti without icing will keep for an extra week.

🙋🏽‍♀️ FAQ

What kind of alcohol is in limoncello?

Limoncello, originating from southern Italy, is made from a neutral grain alcohol or high-proof vodka infused with lemon zest that is then sweetened. The tangy, strongly lemon flavored infusion is great enjoyed chilled as an after dinner drink or for flavoring desserts.

What is limoncello biscotto?

Limoncello biscotti is a type of crunchy Italian cookie that is flavored with the Italian digestif known as limoncello.

Are you supposed to dip your biscotti in coffee?

You should enjoy your biscotti however you like. That said, biscotti is great for dipping in coffee or tea because it is extra firm and crispy and holds up well for dipping.

Should I chill biscotti before baking?

I've never found a need to chill biscotti dough before baking. The dough does not tend to spread like other cookies.

Should limoncello be kept in the fridge?

Limoncello does not require refridgeration, however, it is best enjoyed cold, so storing it in the fridge or freezer makes sense if you're planning to drink it soon.

Description

These Italian limoncello biscotti, made with limoncello and fresh lemon zest, are a satisfying combination of sweet, tart, and crunchy.


Ingredients

Units Scale

For the biscotti:

  • 6 tablespoons butter, room temperature
  • 1 cup sugar
  • 2 large eggs
  • 2 ounces limoncello
  • zest of 1 lemon (1 ½ - 2 teaspoons)
  • ½ teaspoon kosher salt
  • 1 teaspoon baking soda
  • 2 ¾ cups flour
  • ½ cup chopped hazelnuts

For the icing (optional):

  • 1 cup powdered sugar
  • 2 tablespoons limoncello

Instructions

  1. Preheat the oven to 325 degrees F and line a baking sheet with parchment paper.
  2. Using a mixer, beat the butter and sugar until combined. Add the eggs, one at a time, until incorporated. Stop the mixer and use a spatula to scrape down the bowl as needed. The batter should be light in color and consistency at this point.
  3. Add the limoncello, lemon zest, salt, and baking soda. When combined, at low speed, add ½ cup of flour at a time until incorporated. Then stir in the hazelnuts. Dump the dough out onto a clean, floured counter. If it’s still pretty sticky, which it likely will be, pat the dough with more flour until you can handle it without sticking.
  4. Divide the dough into two equal pieces and shape each into a rectangle about 8 inches long and 4 inches wide. Place them on your baking sheet and bake for 25-30 minutes on a rack in the middle of the oven. The tops should be golden brown and firm to the touch.
  5. Keep the oven on while you let the biscotti cool on the baking sheet for about 10 minutes. Then, transfer them to a cutting board and use a serrated knife to slice the dough into cookies. Slice at a slight angle, with each cookie being about ½ inch wide. You should get 20-22 total pieces of biscotti.
  6. Return the biscotti to the baking sheet. Crowding the pan is OK, as the cookies will not spread. Bake for another 25 minutes or until the biscotti are lightly browned and feel hard to the touch. They will continue to crisp up as they cool. 
  7. To make the icing, whisk the powdered sugar and limoncello in a shallow bowl and until combined. Either dip the biscotti into the icing or drizzle over the top. 

Notes

Roll the dough out on a piece of floured parchment paper to make it easier.

For an alcohol free version, use lemon juice in place of limoncello.
