Not all biscotti are created equal and there is no one perfect way to make it, but I found my favorite. And it’s unlike any biscotti I’ve ever tasted before. Crunchy without breaking your teeth, crumbly in all the best ways, melts in your mouth, and super flavorful with a brown-sugar base. This, my friends, is my best base recipe for biscotti.

From this base recipe, I’ve done almonds & chocolate, mocha & hazelnut, and my favorite: white chocolate pistachio & cranberries. Maybe you prefer biscotti plain? Just add a sprinkle of cinnamon. To be honest, this biscotti tastes incredible with as much stuff or as little stuff as you want. But I like the stuff. And today we’re adding walnuts, lots of zippy orange zest, and plenty of dark chocolate.

So you get an idea of how the process works, here’s a video:

The general layout of biscotti making:

  1. make biscotti dough
  2. divide in half
  3. flatten into two slabs
  4. bake
  5. slice
  6. bake a little longer

Let’s start with the biscotti dough. Traditionally, the only wet ingredient in biscotti is egg, but I like to add a little butter and oil for a more flavorful and rich cookie. The butter is worked into the dough the same way I add it to scones, pie crust, and biscuits. Cold and cut into the dry ingredients. What’s the point? This method ensures that the butter doesn’t melt in the dough prior to baking. Instead, the cold butter will melt in the oven. This helps create pockets of crumbly flakes.

You only need 1 Tablespoon of oil, but it really does make a difference. Less teeth-breaky. What else? I sweeten the biscotti with brown sugar and add just enough baking powder for a little lift. Today’s goodies are cinnamon + orange zest + fresh OJ + walnuts, so add those too.

Divide the biscotti dough in half, then shape into 2 long slabs. Brush with an egg wash. Why an egg wash? To make the tops super shiny and delightfully crisp. Bake the slabs on separate baking sheets so they have enough breathing room. You can just bake both sheets in the oven at once.

Bake Twice!

Now here’s what makes biscotti so unique. It’s baked twice! After the slabs bake for about 25 minutes, cut into slices, then bake the cookies for 8 minutes on each side. That’s a total oven time of 40-45 minutes. Sounds like that length of time would dry out a cookie, no? That’s why we add butter and a smidge of oil. Our biscotti will be crunchy, but the fat guarantees it won’t taste dry.

A generous dunk into dark chocolate finishes things off in the fanciest way possible. By the way, this type of chocolate dunk is the best type of chocolate dunk. I used to only dip one end of the biscotti into chocolate, but that’s clearly wrong.

Each bite should be a chocolate bite!!

If you like biscotti (cool kid!) and you’re intimidated to try it at home or if you don’t like biscotti because you, too, think it tastes like cardboard sticks… I encourage you to try my biscotti recipe. You don’t need to chill the dough, no need for a rolling pin, no mixer required, and no cookie cutters involved!

And this concludes my 5th annual cookie palooza. I feel our cookie sheets and mixers deserve a major break after this, but we all know that won’t happen. Happy baking!!

  • Prep Time: 40 minutes
  • Cook Time: 45 minutes
  • Total Time: 1 hour, 25 minutes
  • Yield: 18 cookies 1x

Description

No more dry or bland biscotti, this dark chocolate orange biscotti has so much flavor!


Ingredients

Scale
  • 2 and 1/3 cups (291g) all-purpose flour (spoon & leveled), plus more for work surface + hands
  • 1 cup (200g) packed light or dark brown sugar
  • 1 teaspoon baking powder
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • zest from 1 orange (about 2 scant Tbsp)
  • 1/4 cup (60g) unsalted butter, cold and cubed
  • 3/4 cup (95g) chopped walnuts*
  • 3 large eggs
  • 2 Tablespoons (30ml) fresh orange juice
  • 1 Tablespoon (15ml) canola or vegetable oil (or melted coconut oil)
  • 1 teaspoon pure vanilla extract
  • egg wash: 1 large egg beaten with 1 Tablespoon (15ml) milk or water
  • two 4 ounce (226g) semi-sweet or bittersweet chocolate bars, coarsely chopped*

Instructions

  1. Preheat oven to 350°F (177°C). Line two large baking sheets with parchment paper or silicone baking mats. (Always recommended for cookies.) Set aside.
  2. Whisk the flour, brown sugar, baking powder, cinnamon, salt, and orange zest together in a large bowl until combined. Using a pastry cutter or 2 forks, cut in the butter until the mixture is crumbly. Stir in the walnuts. Set aside. In a medium bowl, whisk the eggs, orange juice, oil, and vanilla extract together. Pour into the flour/butter mixture and gently mix together until everything is just barely moistened.
  3. Turn dough out onto a lightly floured surface and with floured hands, knead lightly until the dough is soft and slightly sticky, about 8-10 times. If it’s uncontrollably sticky, knead 1-2 more Tablespoon(s) of flour into the dough. Divide the dough in two and place each half onto a baking sheet. Shape each half into an 8×4-inch long rectangle, patting down until each is about 1/2 inch thick. Using a pastry brush, lightly brush the top and sides of each biscotti slab with egg wash.
  4. Bake for 25-26 minutes, or until the top and sides of the biscotti slabs are lightly browned. Remove from the oven, but do not turn off the heat. Allow to cool for 10 minutes. Once the slabs are cool enough to handle, cut each into 1 inch thick slices. Set slices cut sides upright, ¼ inch apart, on the baking sheets. Return to the oven to continue baking for 8 minutes. Turn biscotti over and bake other side for 8 minutes. The cookies will be slightly soft in the centers with harder edges. Remove from the oven and allow to cool for 5 minutes on the baking sheet. Transfer to a wire rack to cool completely before dipping in chocolate. The biscotti becomes crunchy as it cools. Save the baking sheets for the next step.
  5. Melt the chopped chocolate in a double boiler or (carefully!) use the microwave. For the microwave, place the chocolate in a medium heat-proof bowl. Melt in 15 second increments, stirring after each increment until completely melted and smooth. Dip each biscotti cookie in the melted chocolate and place back onto the baking sheets. Sprinkle with any additional orange zest if desired. Allow chocolate to set in the refrigerator or at room temperature.
  6. Biscotti will stay fresh covered at room temperature or in the refrigerator for 1-2 weeks.

Notes

  1. Make Ahead Instructions: Biscotti can be frozen for up to 3 months, with or without chocolate. Thaw overnight in the refrigerator and bring to room temperature before dipping in chocolate and/or serving.
  2. Special Tools: KitchenAid Stand Mixer | Glass Mixing Bowls | Measuring Cups | Pastry BlenderZester | 2-qt Double Boiler | Cookie Sheet | Silpat Baking Mat | Cooling Rack | Pastry Brush | Black Plate
  3. Nuts: You can leave out the walnuts or replace with another type of nut. Or try 3/4 cup of dried cranberries instead!
  4. Chocolate: Chocolate bars are typically sold in 4 ounce bars. I suggest Ghirardelli, Baker’s brand, or Lindt. You can use chocolate chips, but they don’t melt down as smoothly.

Reader Questions and Reviews

  1. I made the Dark Chocolate Orange Biscotti recipe this afternoon. I admit that I was a bit panicky when the dough was so very loose and sticky. I added more flour but not enough for it to look like your firm dough. However, the biscotti turned out beautifully and is delicious. I have so much fun trying your recipes, Sally.

  2. I made these today and they are delicious. I know I can depend on you, Sally! I added homemade candied orange peel along with the fresh and Almonds instead of walnuts. I also added a 1/8 c heavy cream on top of OJ.
    They are fabulous!

  3. Made these with hazelnuts instead of walnuts. Everything went as planned which is not always the case with biscotti. The cook times are for a softer biscotti so next time I will add a few minutes to the second bake as you suggest. For those who are having trouble working with the wet dough….I find “slapping” the dough into submission with floury hands works better then kneading or shaping. And you only need 1 baking sheet if you are are using a very large one. Thank you, this is a keeper.

  4. best biscotti i’ve ever made (and i’ve made a lot)
    my boyfriend has celiac disease so i actually turned these gluten free. i replaced the flour with Bob’s Red Mill cup for cup baking flour and they came out amazing! the texture is perfection and the flavor is beyond!
    will definitely use this recipe as a staple!

  5. Hi Sally,
    I too had a terrible time with the dough. I probably ended up adding an additional third of a cup of flour to make it workable, and even though could only get it into logs after putting it back in the fridge for half an hour.

    I am starting the chocolate dipping (for the first time!) shortly. I’m nervous about using the chocolate bars I bought. Do they firm up again without refrigerating? What is the difference between just doing this and tempering chocolate?

    Thanks!

    1. Hi Laura! Yes, the chocolate will firm up as it cools. You’re welcome to temper the chocolate if you prefer a more snappy and glossy finish. Enjoy!

      1. Can the biscotti recipes be doubled? If so are there any adjustments to the ingredient amounts?

      2. Hi Sue, yes you can double this recipe, but for ideal taste and texture, it’s best to make separate batches. Enjoy!

  6. Hi! I am excited to make these, as I love the combination of chocolate and orange. I was wondering, do the eggs need to be cold as the butter or room temperature?

    1. Hi Madeleine, for best results use room temperature eggs. Happy baking!

      1. Hey, sorry if I’m being daft but what do you mean by semi sweet chocolate. I’m from the UK so we have dark, white and milk. Would it be dark?

        Thanks:)

      2. Hi Emma-Louise! Semi sweet chocolate has about 60% cacao, it would be closer to dark chocolate. Enjoy!

  7. Can this be frozen? (I’m assuming you would freeze the biscotti, forefront, then apply the chocolate?)

  8. Super simple recipe turned out amazing! This was the first time iv made Biscotti! They were a huge hit with my friends and fmaily!
    Even if I forget to slpit the dough…

  9. delicious! I added dried mulberries and walnuts – made a beautiful biscotti! Thank you!

  10. is it possible to you my kitchen aid mixer?
    or will it not come out properly ?
    does it have to be made by hand ?

    1. Hi Jessica, making it by hand ensures that the butter isn’t overworked into the dough (similar to how we cut it into pie crust). You could use a mixer, but it’s much easier to overwork the dough. Best to do so by hand if you can!

  11. Would the cooking time shorten if I were to split the dough into 4 slabs to make a smaller biscotti?

    1. Hi Cat, bake time should be slightly shorter for smaller slabs. Enjoy!

  12. Going to a friends to bake Christmas cookies – can I make the dough ahead of time and put in refrigerator? Bring to room temp before baking?

    1. Hi Barbara, absolutely. You can make and shape the dough (through step 3) and chill in the refrigerator. Up to a couple days, covered, would be fine. Bring to room temperature before baking.

  13. HI, Dee again, I hope you have a chance to answer this before this Christmas… I live in Florida. I have heard before that baking here can be difficult. I’m 74 and my friend is around the same age and we have been baking for quite a few years. We’re from Michigan.
    We never had a problem with cookies or breads there. Last year all of our cookies came out messy! Today I made this recipe. It was so wet. I added about another cup or more to it and it still was a sticky mess and went on the pan very flat. Do you have any suggestions ? I’m completely at a loss! Want to make this in another flavor but am not sure what to do to fix this recipe. I love all your recipes ! I have gone to using only your site because they taste great and usually come out right. I tell everyone about you. If you have any suggestions I would truly appreciate any help. Need to get this right for the future as biscotti is a family favorite.
    Thank you for any help.

    1. Hi Dee, I can definitely help troubleshoot. I wonder if the butter became too warm as you were cutting it into the dry ingredients? This could create a much wetter dough. Make sure the butter is very cold. You could even refrigerate the dry ingredients for 10-15 minutes before cutting in the cold butter. What could also help is adding more flour, such as 1/4 cup (about 30-35g). In warmer or humid environments, a little more flour is always helpful.

  14. These came out as described – the delicious orange flavour pairs beautifully with dark chocolate. The texture of these biscotti is firm, but won’t break your teeth. I did not have issues with wet dough, but I did not work the dough very long (like a scone recipe I left the butter in little chunks). Along with the walnuts, I added some leftover candied orange peel that I had made for my stollen loaves. These are super holiday treats – thank you!

  15. These are delicious and simple to prepare and bake. I used hazelnuts instead of walnuts but otherwised followed the receipe exactly. I will make these again but use a bit less sugar next time as the orange juice sweetens it up a bit and i prefer a milder sweetness in my biscotti.

  16. Hi Sally.

    I just want to clarify: This recipe has 3 eggs added to the dough plus one egg for egg wash? 4 eggs total to make recipe?

  17. These were really easy and good! I followed the recipe with the exception of using chopped hazelnuts instead of walnuts. The orange flavor wasn’t super pronounced, so next time I will definitely include more zest. I didn’t measure the zest but I used one orange, and it may have produced less than 2 tbsp. I would also halve the chocolate as it was more than enough to coat the bottom of each biscotti. I ended up using the extra as a drizzle on top, but it’s probably overkill. Finally, like other posters, I needed a lot more flour to make the dough manageable. Otherwise these were delicious and I’ll definitely make them again!

  18. I’m having a huge issue with the dough consistency. It DID say that you might have to add more flour, after turning it out, but after, like a cup added in it was still like cold goop. I might have just done something wrong, but the other recipes come together so easily? Anyone have suggestions?

    1. Hi Jeremy, Thanks for trying this recipe and we are happy to troubleshoot. Did you make any ingredient substitutions? I wonder if the butter became too warm as you were cutting it into the dry ingredients? This could create a much wetter dough. Make sure the butter is very cold. You could even refrigerate the dry ingredients for 10-15 minutes before cutting in the cold butter.

  19. I just made these and I only dipped half of them in the chocolate. The plain ones are delicious too.
    I had trouble with the dough also. I ended up adding at least another half cup of flour.
    I would like harder/crunchier biscotti. How do I do that?

    1. Hi Nonna! For crunchier biscotti, you can simply increase the bake time. Glad you enjoyed them!

  20. I know this is done by hand so as not to overwork the dough, but it turned them into a disaster for me. It must have been my butter-cutting-in lack of skill that left them not blended enough. They were underdone in the middle and kind of tasteless. Irony is I’m a very good baker and have been making everyone’s favorite biscotti since the ’90s. I’ve always made classic biscotti (no butter or oil) and I guess I should go back to that! Guess my input here is: make sure you cut the butter in to the point where there are no butter lumps visible.

  21. I made these dark chocolate biscotti by subbing 1/2 c Dutch Process cocoa for 1/2 cup of the flour, used chopped honey almonds, added 1/3 cacao nibs and almond extract with the orange extract and zest and they were amazing! (Also needed to add about 1/2c extra flour at end to get it workable).
