Keto chocolate biscotti is a deliciously crisp sugar-free cookie, perfect for dipping in coffee, milk, or tea. They’re made with hazelnut meal so they’re completely grain free and low carb.
I’ve given my keto chocolate hazelnut biscotti an update! I’ve added new photos, of course, and updated the recipe with an easier method for getting these Italian cookies super crisp, just like the real deal.
You know I love my keto biscotti. Why else would I have 13 different recipes for this crisp twice baked cookie on my blog? And that’s not even including the many biscotti recipes I have written for other websites and for my keto cookbooks.
In fact, I had updated this chocolate hazelnut version a while ago so that I could include it in The Ultimate Guide to Keto Baking. I am only just now getting around to updating it here!
Chocolate biscotti is a perfect light morning snack
I am a morning person, though and through. I love being up before dawn, sipping my coffee, and enjoying the quiet before the rest of the family wakes up.
And I’ve always been this way. I distinctly remember that moment in high school when a friend rather grumpily remarked that I was the only person she knew who could be so cheery first thing in the morning. Let it be noted that I wasn’t cheery to be at school, per se; I was simply happy to be among my friends every day.
These days, I don’t have much appetite first thing in the morning. I often don’t eat anything at all until after 10 am, when I break my fast with a big hearty meal.
But sometimes I want a small, light snack to go with my coffee, to see me through the morning. And nothing goes better with coffee than a crisp low carb biscotto.
Biscotti are delicious enough on their own. But they are absolutely magical dipped into a hot coffee or a cappuccino. Magical, I tell you!
How to make Keto Chocolate Hazelnut Biscotti
Traditional biscotti isn’t, obviously, low in carbs, but the texture and taste can be relatively easily replicated using keto ingredients. Let me show you how it’s done.
Use finely ground nut flours
You can use almost any nut or seed flour to make keto biscotti, as long as it’s finely ground enough. When I first tried making these back in 2011, I ground the hazelnuts myself. They were incredibly fragile and crumbly, so I do recommend using store-bought nut flours.
Erythritol based sweeteners
I have a lot of experience making keto biscotti and other keto cookies, and I’ve experimented with a lot of sweeteners. Trust me when I say that the only sweetener that will give you a crispy biscotti texture is erythritol. You can use Swerve, Lakanto, or other erythritol.
But if it contains even the smallest amount of allulose or xylitol, they won’t crisp up properly. So read your labels and make sure you know what’s in your sweeteners.
Cutting the biscotti
Biscotti recipes are always twice baked, first as a log and then as individual biscuits. They can be a bit fragile when you firsts cut them into slices. I recommend using a non-serrated knife, and cutting straight down rather than sawing back and forth. The back and forth motion tends to tear at the log too much and the edges crumble.
You can saw a bit back and forth to break the surface at the top, but once you’ve make a small cut, press down firmly in one swift motion. And be sure to use a sharp knife!
Chop the added nuts
If you’re adding anything into your biscotti, such as nuts or sugar-free dried cranberries, be sure to chop these additions finely before adding. This also helps the dough be more cohesive and less fragile when you cut it into slices.
Leave them in the oven
Let the sliced biscotti sit inside a warm oven until they are completely dried out. I turn my oven off after the second baking and leave them in there until they are completely cool. It’s the best way to get them truly crisp.
Can you make keto biscotti in advance?
One of my favorite things about biscotti is how well they last compared to other keto baked goods. They are meant to be hard and dry, and they are perfect for making ahead. I’ve even taken them traveling with me.
You can keep them on the counter for up to two weeks in a covered container. There is no need to refrigerate them.
They also freeze very well. I’ve made keto biscotti several months in advance of the holidays and frozen them in covered containers. Once thawed, they taste just as good as they did fresh!

Keto Chocolate Hazelnut Biscotti
Ingredients
- 1 3/4 cups (180 g) hazelnut flour
- 1/2 cup (91 g) Swerve Sweetener
- 1/4 cup (21.5 g) cocoa powder
- 1/4 cup (30 g) finely chopped hazelnuts
- 1 tsp baking powder
- 1/4 tsp (0.25 tsp) salt
- 1/4 cup (54.5 g) toasted hazelnut oil, (or melted butter)
- 1 large egg
- 1/2 tsp (0.5 tsp) vanilla or hazelnut extract
Instructions
- Preheat the oven to 325F and line a baking sheet with a silicone mat or parchment paper.
- In a large bowl, whisk together the hazelnut flour, sweetener, cocoa powder, chopped hazelnuts, baking powder, and salt. Stir in the oil, egg, and extract until the dough comes together.
- Turn he dough out onto the prepared baking sheet and shape into a low, flat log about 10 by 4 inches. Bake until firm to the touch and lightly browned, 22 to 25 minutes. Remove from oven and let cool 30 minutes. Reduce the oven temperature to 250F.
- Using a sharp knife, gently cut into 14 slices. This is easier with a non-serated knife, and cutting straight up and down, as opposed to a sawing motion.
- Place the slices, cut-side down, back onto the baking sheet. Bake 15 minutes, and then carefully flip the cookies. Turn off the oven and let the biscotti sit inside until cool.

looks sinfully delicious!
Carolyn, congrats on the Top 9!! Are these the same biscotti who were not coorperating?? They look just right to me. Nicely done!
This is the answer for something alongside morning coffee! Biscotti that is low carb and gluten free, what a great idea. These look delicious.
Oh WOW I am so glad to have found your blog!!!! My husband is on a low carb (I don't want to say diet) way of eating.I am always looking for new recipes so that he doesn't get bored with the same ole things.I am really excited to give these a try. Thanks.
Nice looking Biscotti! Congrats on Foodbuzz Top 9!!
I read this twice yesterday and again today only to realize, I didn't comment. I am not a morning person but I get more done in the mornings. With that biscotti, anyone would be a morning person. So nice and crumbly. Thanks for the tips on how to make it more or less crumbly. Very helpful! (Hope your little one is feeling better soon.)
Your description of being a morning person is cute. I've never been a huge morning person. At my former job, the cubicles were low so we could all see each other and talk over the wall. The man next to me rather cheerily said "Good morning" to me every morning when I came in. I really wished he would stop doing that until at least an hour later when I was ready to speak. 😉 Great looking biscotti!
Biscotti is such a delight, and these are a wonderful version.
Bon appetit!

=:~)
I needed these before my race a few days ago when I was expected to get up and eat at 3 AM before running 13 miles! My stomach was just not ready for real food yet. But these would have been PERFECT!
Wonderful, and low-carb too! My usual biscotti recipe uses ground almonds but over Xmas I ran out and oculdn't find any in the stores so I made a more traditional biscotti and didn't like it half as much. I think hazelnut would definitely be a winner for me!
Carolyn this Biscotti looks amazing! And it's low carb and gluten free, never would have guessed!!
Oh wow, these look wonderful! I especially love chocolate flavored biscotti. I have yet to try making them myself, but now I'll definitely have to try them after seeing these. Congrats on making top9!
Love the flavours in these, they look so rich and crunchy!
I can't skip breakfast, I always have something healthy, it's just a habit I guess but if I go without on the odd occasion, I feel very flat.
Hi Carolyn! I'm a big believer in breakfast, too, but I definitely know how it can be a struggle to nourish myself in the morning what with the little ones. My coffee often goes cold in the mornings. But for my afternoon cup, this biscotti would be perfect! Love chocolate and hazelnut!
You are on roll these few weeks…you should really play lottery! I am really! Congrats on one more top 9..your food is always mouthwatering!
Chocolate and hazelnut! Must be a great flavor for a biscotti :).
