At #3, chopped hazelnuts replace the orange and cranberry combination in #4. Expect an earthy, nutty flavor and a firm crunch, without the chewy dried fruit of the previous recipe. An optional small amount of espresso powder adds a coffee accent. Choose this version if you want hazelnuts to be the main flavor.
Servings 12 people
Prep Time 15 minutes
Cook Time 45 minutes
Total Time 1 hour

Ingredients
  

  • 2 cups All-purpose flour (spooned and leveled)
  • 3/4 cup Granulated sugar (provides the traditional crisp snap)
  • 1 tsp Baking powder (for a slight, necessary rise)
  • 1/4 tsp Salt (enhances the deep, nutty flavors)
  • 1/2 tsp Instant espresso powder (optional, but it subtly enhances the roasted hazelnut profile without overpowering it)
  • 3 large Eggs (room temperature)
  • 1.5 tsp Vanilla extract
  • 1 cup Whole skinless hazelnuts (roughly chopped; the second bake will toast them to perfection)

Instructions
 

  • Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper and set it aside.
  • In a medium-sized mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, salt, and instant espresso powder.
  • In a separate large bowl, lightly beat the room-temperature eggs, then whisk in the vanilla extract until fully combined.
  • Gradually pour the dry flour mixture into the wet egg mixture. Use a sturdy wooden spoon or spatula to mix until a thick, cohesive dough begins to form.
  • Pour in the chopped hazelnuts and gently fold them into the dough. You may need to use your hands to ensure the nuts are evenly distributed throughout the thick mixture.
  • Turn the dough out onto a lightly floured work surface. Divide it equally into two halves. Shape each half into a log about 9 inches long and 2.5 inches wide. Place the logs on the prepared baking sheet, spacing them a few inches apart.
  • Bake for 25 minutes, or until the logs are firm to the touch and have developed a pale golden color.
  • Remove from the oven and let the logs cool on the baking sheet for exactly 10 to 15 minutes. Reduce your oven temperature to 325°F (165°C).
  • Transfer the semi-cooled logs to a cutting board. Using a sharp serrated knife, slice them on a slight diagonal into 3/4-inch thick pieces. Press down gently but firmly to slice cleanly through the hazelnuts.
  • Place the sliced biscotti cut-side down back onto the baking sheet. Bake for 8-10 minutes, carefully flip each piece over, and bake for a final 8-10 minutes. They should be deeply golden, completely dry, and heavily toasted. Cool completely on a wire rack before serving!

Working with Hazelnuts

Roughly chop the skinless hazelnuts before folding them into the dough so the pieces are distributed throughout both logs.

After the first bake, let the logs rest for 10–15 minutes. Use a sharp serrated knife with a gentle sawing motion to cut through the nuts without pulling them out. Lower the oven to 325°F (165°C) for the second bake and turn the slices halfway through.

Next: Decadent Double Espresso Biscotti. Espresso becomes the main flavor, supported by cocoa powder, with optional mini chocolate chips for pockets of sweetness.

    I mixed up the flour and sugar proportions and ended up with a mess. Oops!

      Don’t feel bad! Mistakes happen. Just try again with the right proportions! 😊

    Yummy! I’d like to try with almonds instead of hazelnuts next time. Anyone else tried that?

  3. User avatar nakesha.flatley says:

    Not bad, but I thought they were too hard. Maybe I left them in the oven too long?

    1. User avatar buford.emard says:

      Yeah, overbaking can definitely make them hard! Just try reducing the baking time next time. Hope the next batch turns out better!

    Biscotti? More like bis-no-thank-you. Not a fan! The flavor just didn’t do it for me, maybe I used bad hazelnuts?

  5. User avatar tissues_with_issues says:

    Can you use almond nuts instead? Hazelnuts are hard to find! Help pls.

  6. User avatar ShanksOnePiece says:

    Didn’t add espresso powder becuz I didn’t have it. Still came out decent. Just saying!

      That’s great to hear! Sometimes you gotta work with what you have. What did you think of the flavor without the espresso?

  7. User avatar allison.kozey says:

    The recipe was easy to follow, but I didn’t have hazelnuts. I used almonds instead and they turned out great!

    I tried makin these but I think I measured wrong or somethin’… the dough was too sticky. What did I do wrong?

    1. User avatar Glorfindel says:

      4 stars
      It sounds like you might have added too much flour or not enough flour depending on how you measured. Make sure to spoon flour into the measuring cup and level it off! It’s easy to mess that up. Hope it works out next time!

    Absolutely delicious! I followed the recipe exactly and they came out perfect! Crispy and full of flavor. Will definitely make again!

    I dunno about these. My family says they taste burnt. I guess I left them in too long.

  13. User avatar cole.pouros45 says:

    I chopped the hazelnuts too big and some pieces fell out. Still crunchy, but next time I’ll go smaller so every bite has nuts.

    I tried this recipe, but it was kinda hard to follow. I mixed up the baking times and ended up burning them a bit. Still tasty, but I think I need to practice more.

    These biscotti turned out amazing! Just the right crunch and flavor. Definitely making them again!

    I messed up the eggs part and used 4 instead of 3. Guess I’ll be calling them eggy-biscotti now!!! 😂

      Eggy-biscotti sounds fun! Can’t wait to try it like that! 😂

    Why do we need so many eggs? Seems a bit excessive. 🤔

  31. 2 stars
    Why 10–15 minutes cooling? I skipped it because I was hungry lol. Still edible, but cutting was messier and some pieces crumbled more than I wanted. Lesson learned.

    1. User avatar suspiciousCommentator says:

      4 stars
      Lol I’ve done that too—cooling time always feels optional when you’re hungry 😅 Good on you for trying anyway.

  32. User avatar marita.conroy says:

    Disappointing. They came out too hard for my liking. I thought I was going to get a nice crunchy snack but it was just tough. 2.

    1. User avatar marquis.kub says:

      4 stars
      Sounds like you might’ve overbaked them a bit! Biscotti should be crunchy, but not like a rock. Maybe try reducing the second bake time next time.

  33. User avatar Helena Hanbaskett says:

    4 stars
    Only complaint: my hazelnuts weren’t skinless like the label said and the texture was a little weird. Flavor was still amazing though. Next time I’ll roast and rub them myself.

  34. User avatar Dwarven Shpere says:

    4 stars
    I used a little less sugar because I’m trying to be “good,” but it still turned out tasty and crunchy. The espresso note is subtle—not weird.

  35. User avatar jeannette.lindgren27 says:

    They seemed good, but the second bake was too long for my taste. Maybe adjust the time next time? 4/5.

  36. User avatar ezequiel.hammes says:

    I tried making these but the dough was super sticky. I must have messed something up. I’ve never made biscotti before, so maybe it’s just me. 3/5.

  37. 4 stars
    Pretty good, but mine were a bit too dark on the final round. I think my oven runs hot. Next time I’ll check at 7 minutes instead of waiting for “deeply golden.”

  38. User avatar Eccentrica Gallumbits says:

    4 stars
    “Exactly 10 to 15 minutes” is a lot of pressure 😅 I went 12 and it worked. Biscotti is kind of picky like that, but this recipe was clear.

    1. User avatar Arthur Philip Deodat says:

      5 stars
      I get that 😅 I always hover like a helicopter at the 10–15 minute mark. Glad it worked for you!

  39. User avatar tissues_with_issues says:

    Biscotti always remind me of my grandma. She used to make them every Christmas! So happy I found this recipe. ❤️ 5 stars!

  40. User avatar na.wiza2019 says:

    These look seriously crunchy. I love how you double-toast the hazelnuts—most recipes don’t go far enough for that nutty depth.

  41. 1 star
    This recipe is a waste of time. Biscotti should be simple, but this was too complicated! Who needs espresso powder anyway?

  42. 3 stars
    I don’t get why “skinless hazelnuts” matter—my grocery didn’t have those, so I used regular roasted hazelnuts with skins. Still good though.

  43. User avatar geoWizard says:

    Wow, these biscotti are amazing! I love how crunchy they are. Perfect with my coffee!

    1. User avatar jesica.lueilwitz70 says:

      They really are the best with coffee! I make them all the time. Perfect with that crunchy texture!

  44. User avatar Owa Daim says:

    Instant espresso powder optional? I added it and it absolutely did overpower a bit for me—coffee flavor was strong, not subtle.

  45. User avatar robt.nikolaus35 says:

    Biscotti? I thought it was just for dunking. Turns out it’s kinda fancy! 😂

  46. User avatar shanice.lockman says:

    The pale golden first bake then deeper golden second bake is accurate. I finally made biscotti that actually stays crunchy for days.

  47. User avatar joe_banana says:

    5 stars
    These look dangerously crunchy. The double-toast step is exactly what I want in biscotti—big flavor, no chew. I added extra espresso and it still felt balanced.

  48. User avatar Anita Knapp says:

    1 cup hazelnuts seems like a lot—dough was really thick. I actually loved that texture. Would make again.

  49. User avatar jeremy.deckow15 says:

    Not gonna lie, 25 minutes + then 8-10 + 8-10 felt like overkill, but it worked. They’re very dry in a good biscotti way. Wife’s asking for more.

  50. User avatar eveline.hamill says:

    5 stars
    Just made these—my kitchen smelled like a fancy café. The double-toasting really earns the crisp. Hazelnuts toasted to that deep golden color. Followed the 10–15 min rest and it sliced way cleaner than I expected.

  51. 4 stars
    I followed the steps pretty closely, except my oven runs hot, so I pulled them a couple minutes early. Still turned out deeply golden and crunchy. Next time I’ll chop the hazelnuts a bit smaller for more even bites.

  52. User avatar lynwood.senger86 says:

    2 stars
    I followed it mostly, but I don’t own a serrated knife so I kind of hacked at the slices—now it’s more like broken cookies. Still tasty, but yeah not pretty.

    Delicious! Made a batch for my book club, and they were devoured in minutes. Easy to follow too.

  54. User avatar Android 19 says:

    The espresso powder is optional but I would still keep it. It didn’t taste like coffee, just made the nut flavor deeper. Nice little trick.

  55. User avatar earnest.rodriguez37 says:

    not gonna lie, i dont trust the espresso powder being “optional” lol. i used it and now i’m convinced it’s mandatory. great roasted nut vibe.

    Not sure what went wrong, but mine turned out all doughy. Maybe I added too much flour? 🤔

  57. 3 stars
    I think 3/4 cup sugar feels high? Mine were sweet sweet, not just “crisp.” Still tasty, but I’ll cut sugar next time to match my preferences.

    1. User avatar dion.gutmann76 says:

      4 stars
      I also thought it was high the first time, but mine came out perfect—like “crackly” crisp. If yours were sweet enough, yeah, I’d try 1/2 cup next batch.

    2. 5 stars
      Totally get that. Biscotti is supposed to be pretty sweet/crisp, but 3/4 cup sugar can absolutely feel like a lot depending on your taste buds. Cutting it next time makes sense!

  58. 5 stars
    I’ve never had biscotti that actually tastes like toasted nuts, so I was skeptical. But these are surprisingly good—crisp, not too sweet, and not bitter.

  59. User avatar taneka.jacobson says:

    4 stars
    The instructions say “exactly 10 to 15 minutes” which is hilarious. I did 12 and they still turned out fine.

  60. 4 stars
    Okay wow. I don’t even usually bake biscotti and this turned out. However I did burn one tray a teeny bit because I was zoning out—so keep an eye on that last 8-10 minutes.

  61. User avatar Liana Runte says:

    4 stars
    Easy steps, and I like that it makes two logs—portioning is nice. The outside got crunchy, but the inside still had a slight chew. Still tasty though!

  62. User avatar tobias.hessel36 says:

    5 stars
    Hazelnut biscotti is my whole personality right now and this recipe gets it right. The logs sliced clean, and the snap is real. Coffee break = saved.

  63. User avatar roland.keebler76 says:

    2 stars
    Not bad, not great. Too much sugar for my taste, and the biscotti ended up harder than I like—like “sink your teeth in” hard. Flavor is nice with the hazelnuts, but I’d cut sugar next round.

    1. User avatar gene.steuber85 says:

      4 stars
      Thanks for the honest feedback! I wonder if your logs were on the thicker side or the second bake went a minute or two too long—biscotti gets brutal fast. What I do is pull them when they’re “deep golden but not rock-hard” and let them firm up as they cool.

    2. User avatar donn.fisher51 says:

      5 stars
      I feel you on the sugar—3/4 cup is a lot. Next time try 1/2 cup and maybe add a pinch more salt to keep the flavor punch. Hazelnuts can handle it without needing all that sweetness 😅

  64. User avatar nolan.fay says:

    4 stars
    My serrated knife chewed up one loaf—thought I was cutting wrong but I think it needed more cooling time. After cooling longer, slicing got way easier. Texture was excellent once I fixed that.

  65. 3 stars
    Not bad, but mine spread a bit and the logs weren’t as clean. I think my eggs were not room temp (kinda forgot).

    1. User avatar ShanksOnePiece says:

      3 stars
      Mine spread too 😅 I thought it was the butter at first (didn’t even realize this recipe doesn’t use any). Next time I’ll chill the dough or make sure the eggs are room temp.

    2. User avatar merissa.grimes59 says:

      4 stars
      Haha I’ve done the exact same thing—forgetting to bring eggs to room temp can totally mess with the dough consistency. Still, sounds like you were close!

  69. User avatar bonny.koelpin2018 says:

    The double-toasting part is spot on. My house smelled like a coffee shop for hours. Crisp all the way through!

  70. User avatar stewart.schmitt22 says:

    3 stars
    Good flavor but mine spread a little and the logs weren’t as uniform as pictured. I think I didn’t let the first bake firm up enough—25 minutes might be borderline for my oven.

    1. 5 stars
      Oh that’s helpful to know—mine were pretty uniform, so your point about the first bake makes sense. I’d try going a few minutes longer at 25 if your oven runs cool/slow.

  71. User avatar ALTplusF4 says:

    2 stars
    Why do we have to cool exactly 10-15 minutes? I kinda guessed and still baked fine, but I feel like that instruction is overly strict. Also, mine burned a bit on the edges despite flipping carefully.

    1. User avatar winfred.donnelly says:

      4 stars
      I think the 10–15 min is mostly about letting the logs set a bit so they don’t crumble when you slice. If yours still worked, you’re probably in the same ballpark. Burning edges though—maybe your oven runs hot or the logs were a bit too close to the heating element?

    2. 3 stars
      Exact 10-15 minutes is silly tbh. I always skip the timer and it’s fine lol. Edges burning usually means I baked too long the second toast or my pieces were thinner than 3/4 inch.

  72. User avatar Vroomfondel says:

    4 stars
    I was skeptical about “exactly 10 to 15 minutes” cooling, but it worked. My first tray was a bit darker when I rushed the cooling, so yeah, precision matters.

  73. User avatar Douglas Labadie says:

    4 stars
    So dry I had to dunk in milk 😂 But maybe that’s the point. Next time I’ll slice thinner or check earlier.

  74. User avatar Twinrova says:

    3 stars
    Not bad, but mine came out a little too dry and crumbly—maybe my logs were thinner than 2.5 inches? Also I forgot the second flip at one point and had to re-bake.

  75. User avatar elroy.franecki says:

    4 stars
    lol biscotti go crunch. I messed up once tho—forgot to flip pieces and they were unevenly toasted. Still ate them all. Great recipe for using up hazelnuts.

  76. User avatar anonymous_hacker says:

    4 stars
    I followed the steps pretty much. Mine came out a little darker than expected, but honestly the espresso + hazelnuts taste amazing together.

  77. User avatar Michael83 says:

    2 stars
    Not sure about using espresso powder with hazelnuts—felt a little bitter to me. Also my dough seemed super thick, so mixing took longer than the recipe made it sound.

  78. User avatar CTRLplusW says:

    3 stars
    I followed it pretty much, but mine came out a bit too dark on the second bake. Next time I’ll start checking at 8 minutes instead of waiting for “deeply golden.”

    meh. too much work for cookies that last. i guess the nuts taste ok but i wanted softer. will not make again

  80. User avatar chung.daniel says:

    4 stars
    I was skeptical about the espresso powder, but it doesn’t taste “coffee-y”—more like it boosts everything. My dough was thick and a little sticky, but hands helped and it worked. Next time I might chop the nuts smaller so every bite is even.
