Wonderfully crisp and crunchy and brimming with nutty flavour, these Keto biscotti are the perfect partner for a hot cup of tea or coffee at any time of year.
Biscotti, also known as cantucci, are twice-baked, oblong Italian almond biscuits that were created in the city of Prato.
While some people associate them with the holiday season and Christmas, they're traditionally enjoyed all year round.
The word biscotto actually originates from the medieval word "biscoctus", which means "twice cooked". This rendered the cookies extra dry and crunchy and they could be stored for long periods of time.
Ingredients
Traditionally, biscotti are made with flour, sugar, eggs and almonds or pine nuts. To lower the carb count, my keto biscotti contain almond flour. I also replaced the sugar with granulated erythritol.
Here are all the ingredients:
- Almond flour - I'm using ground almonds, which is equivalent to regular almond flour in the US. If you want to use super-fine almond flour, consider reducing the amount by 1 tablespoon to prevent your dough from becoming dry.
- Sweetener - I recommend erythritol-based sweeteners. Use either pure erythritol, or a monk fruit or stevia blend. They make the crunchiest cookies. Xylitol or allulose won't set as hard.
- Baking powder
- Sea salt
- Egg - I used a large egg.
- Almond extract - In my opinion, almond extract is essential as it increases the almond flavor. Vanilla extract could be a substitute.
- Nuts - I used pistachios and pecans.
Instructions
This section contains step-by-step instructions and photos that show how to make this recipe. See the recipe card for full information on ingredients and quantities
Step 1
Mix the dry ingredients in a bowl - almond flour, granulated erythritol, baking powder, nuts and the pinch of salt.
Step 2
Add the wet ingredients - beaten egg and almond extract. Stir, then knead until a dough forms.
Step 3
Roll the dough into a log shape and place it on a cookie sheet lined with parchment paper. Mine was 28 centimetres long.
Step 4
Flatten into an oblong biscotti shape - flat at the bottom, rounded at the top. Bake on the middle shelf for 25-30 minutes until lightly browned.
Step 5
Remove from the oven and let cool completely. Then cut into biscotti slices with a serrated knife.
Step 6
Return to the oven for another 12-15 minutes to allow the biscotti to crisp up. Rotate the baking sheet if you notice that the biscuits at the back brown faster than the ones in the front.
Expert Tips
Biscotti recipes with wheat flour can be rolled into a log and will spread into the oblong shape whilst in the oven. This does not happen with almond flour biscotti. Be sure to flatten your log into the desired shape!
Almond flour lacks gluten and is therefore more fragile. Use the sharpest serrated knife you own for cutting the log. Also, to prevent the cookies from breaking, I pressed the side of the cookie I was cutting against the log to stabilise it.
Recipe FAQs
Reduce the amount of almond flour by 1 tablespoon and add 3 tablespoons of unsweetened cocoa powder. You may also need to increase the amount of sweetener by 1-2 tablespoons.
Butter is not an ingredient in traditional biscotti.
If you do, the cookie slices will brown more all over. To prevent this, you could try reducing the oven temperature and leave them in for longer.
I have not tried this myself, but it could work well. Flax is a great binder. I use it in my keto granola and it helps make it super crispy.
Xanthan gum helps to bind and thicken ingredients. However, it makes bakes softer. And we want our biscotti to be crunchy!
Variations
Vary the nuts. I used half pistachios and half pecans. Almonds, hazelnuts, pine nuts and pistachios can be used whole. If you're using large nuts such as walnuts or pecans, break them into slightly smaller pieces first so they don't stick out of your log.
Vanilla extract. I think it's the almond extract that makes the recipe taste special. But if you don't have it, vanilla extract or powdered vanilla bean also works.
More Christmas flavor. Add 1 teaspoon of orange extract or 1 teaspoon grated orange zest. Or add winter spices such as 1 teaspoon cinnamon, ยผ teaspoon crushed cardamom and โ teaspoon nutmeg. ยผ cup of sugar free dried cranberries would also work well!
Chocolate. Dip one end of the keto biscotti in sugar free chocolate or drizzle melted dark chocolate (minimum 85% cocoa solids) over them. You could even add ยผ cup sugar free chocolate chips to the dough before baking.
Storage
Low carb biscotti should be stored like any other cookie: In an airtight cookie jar. They stay fresh for several weeks.
You can also store them in the freezer for up to 3 months.

This is such a fantastic recipe and I really appreciate all the detail and options you always give in your keto recipes. Thank you for putting in the efforts you do in creating super tasty healthy options that are wonderfully explained. Making my 2nd batch this morning going to try another variation you suggested. My entire family devoured yesterday's batch. Love your recipes and shares so we can make tasty treats that satisfy the whole family.

Biscotti have always been my coffee shop sweet treat and this recipe is perfect. I tweaked it very slightly to accommodate my sweet tooth by using a generous 1/3 cup of erythritol, a little more almond extract and just hazelnuts. On the second bake after 10 minutes I turn the oven down to 100 for about 30 minutes and then turn it off and let the Biscotti cool in the oven. I left them overnight and they were so hard and crisp and just perfect.
Thank you. Since I started eating low carb and making your recipes I don't feel deprived at all and I have lost 9 lbs in weight too.
Katrin Nรผrnberger
Congrats on the weight loss! I'm so happy you like the recipes - and thank you for sharing your tips.
Alison
Iโd like them a little sweeter and I would also like to know if adding butter would ruin them?
Thank youโฆdelicious other than that and I cut them too soon.
Katrin Nรผrnberger
You can definitely add a little butter, I don't think that would ruin them.
Denise
Absolutely delicious!! I added the sugar free dried cranberries to the nut mixture and used both almond extract and a little vanilla bean paste. My only mistake was to make them in my convection toaster oven. They did not cook evenly at all and started to burn on top, so I covered them with foil and finished cooking them and even though I waited for them to cool, they broke apart when I sliced them. I put them back into the regular oven to finish the cooking process and even though they weren't pretty - they were so delicious. I'm making a second batch which will go into the regular oven.
Belinda sayce
The recipe is fantastic thank you..
I followed the recipe but mine didnโt come out very crispyโฆ. Any tips ?
Katrin Nรผrnberger
Yes. First of all, low carb cookies crisp up as they cool. I find that they are even crispier on day 2! Also, it is essential to bake these until all moisture has evaporated. For example, if your oven is a little less hot than mine, or if you have sliced the cookies slightly thicker than I did, the baking time needs to increase accordingly. Hope this helps!
Nicole
Fantastiskt lรคtt och otroligt goda.
Graziana
Thanks for a great recipe. The flavour is just sweet enough to please and the consistency is fairly 'snappy'.
The only issues for me was over-browning on both steps of the baking process. It may be because I used allulose instead of erythritol. Or maybe my vintage electric oven is too hot. I will definitely make again though, and I'll adjust along the way. Thanks again!
Katrin Nรผrnberger
Yes, I think that the allulose is the issue here as it browns just like sugar. To prevent this, put aluminium foil over the cookies once they are golden. This way, they do not burn.
Alix Singleton
Excellent recipe. No one knows any better and they last, in a jar, forever! Thanks so much for another excellent recipe
Bella
I can taste these just looking at you โsnapโ one- yum! Could I sub maple sugar in here for the sweetener, add a touch of vanilla extract, and try walnuts? Iโm a low-carb yet not strictly keto girl and want to attempt to pull off a version similar to my beloved grandmotherโs recipe I once knew in childhood.
Katrin Nรผrnberger
Yes, that should work!
Tina
I made the recipe exactly as stated. After I cut them, I put them back in oven for a few minutes to get the inside crunchy, too. I am Italian and this is amazing. I will be making these several times a month!
