Keto Chocolate Biscotti are deliciously crisp Italian-style biscuits, perfect for dipping into coffee or tea. Made with hazelnuts and a sugar-free chocolate drizzle, they look and taste like they came from a bakery!
Chocolate and hazelnut together is a magical combination. Magical, I tell you! Anyone who has ever tasted my Keto Nutella understands what I am talking about. I like to bring those two flavors together as often as possible.
These Keto Chocolate Hazelnut Biscotti have been on my website for over 15 years now, if you can believe it. And every time I make them, I remember why I love them so much. They have mild sweetness and serious crunch, just like the classic Italian cookie. And they taste so good dipped into my morning coffee.
If you love my classic Keto Biscotti, this chocolate version is a must-make!

Susan says: “Carolyn, I just tried these as part of a biscotti-baking rampage yesterday. They are divine and held together beautifully; this morning they taste even better than they did fresh out of the oven.“
Ingredients and Substitutions
- Hazelnut meal: There are several brands of this but I recently found a blanched version from Wellbee’s that makes the texture even better. You can also use almond flour.
- Sweetener: You really do need an erythritol sweetener for crisp biscotti. Any amount of allulose or xylitol will prevent them from crisping up properly.
- Cocoa powder: I recommend Dutch process cocoa powder for a deeper chocolate flavor.
- Xanthan gum: This helps give the biscotti a little more stability so that they hold together better. You can skip it but they may be more fragile.
- Hazelnut oil: I like using hazelnut oil for increased hazelnut flavor. But you can use any neutral tasting oil or melted butter.
- Hazelnut extract: You can also use vanilla extract.
- Chopped hazelnuts: Chop them fairly finely, as larger pieces make it harder to cut through the biscotti.
How to Make Keto Chocolate Hazelnut Biscotti
- Combine the dry ingredients: In a large bowl, whisk together the hazelnut meal, sweetener, cocoa powder, baking powder, xanthan gum, and salt.
- Add the wet ingredients: Stir in the oil, egg, and extract until the dough comes together. Stir in the chopped hazelnuts.
- Bake once: Form into a long, low log and bake until firm. Remove and let cool 30 minutes.
- Cut into slices: Carefully slice the log into 14 slices, and spread around the baking pan.
- Bake again: Return to the oven and bake on low heat for another 15 to 20 minutes, then turn off the oven and let the biscotti remain inside until cool.
- Drizzle with chocolate (Optional): Melt the chocolate in a microwave safe bowl and drizzle over the cooled biscotti.
Carolyn’s Tips for Success
I recommend using commercially ground nut meals for keto biscotti, as it is very difficult to grind them finely enough at home. I have tried it and they end up more fragile and crumbly.
As previously stated, ONLY erythritol-based sweeteners will produce a crisp cookie. If you wish to cut back on the erythritol, try adding some pure stevia or monk fruit to increase the sweetness.
Take care when cutting the biscotti into slices, as it can be a bit fragile. I recommend a very sharp knife, and sawing lightly until it breaks the surface. Then just cut straight down so the sides don’t tear.
Make Ahead Recipe
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 can last up to two weeks in the counter, so they are perfect for advance prep. I’ve even taken them with me when traveling!
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 Recipe
Ingredients
- 1 3/4 cups (180 g) hazelnut flour
- 1/3 cup (63.33 g) granular sweetener, (erythritol-based)
- 1/4 cup (21.5 g) cocoa powder
- 1 tsp baking powder
- 1/2 tsp xanthan gum
- 1/4 tsp (0.25 tsp) salt
- 1/4 cup (54.5 g) toasted hazelnut oil, (or melted butter)
- 1 large (1) egg
- 1/2 tsp (0.5 tsp) vanilla or hazelnut extract
- 1/4 cup (30 g) finely chopped hazelnuts
- 1 ounce (28.35 g) sugar free chocolate chips, (optional)
Instructions
- Preheat the oven to 325ºF and line a baking sheet with a silicone mat or parchment paper.
- In a large bowl, whisk together the hazelnut flour, sweetener, cocoa powder, baking powder, xanthan gum, and salt. Stir in the oil, egg, and extract until the dough comes together.
- Turn the dough out onto the prepared baking sheet and shape into a low, flat log about 10 by 3 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 275ºF.
- Transfer the log to a cutting board and carefully cut into 14 slices. This is easier with a very sharp non-serated knife. Saw back and forth only until you break the surface of the log, then cut straight down from there.
- Arrange the slices back on the baking sheet with plenty of space between them. Bake another 20 minutes, then turn off the oven and let the biscotti sit inside until cool.
- Place the chocolate chips in a small microwave safe bowl and melt in 30 second increments, stirring in between until smooth. Alternatively, you can melt the chocolate in a heatproof bowl over a pan of barely simmering water.
- Place the chocolate in a ziplock bag with a small corner snipped off. Drizzle over the cooled biscotti and let set.

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 :).
