I love a fancy cake. But secretly, my favourite keto dessert are cookies. They are so easy and quick to make. Plus, they have a handy in-built portion control.
Even better, you only need a handful of ingredients. I adore these keto almond butter cookies (3 ingredients), my sugar free nutella cookies and sugar free meringue cookies (both 4 ingredients).
I created these low carb walnut cookies after a trip to Italy many years ago, where I was introduced to dolci di noci - the classic Italian walnut cookie.
Since it contains only 4 ingredients, it was very simple to turn the original recipe into a sugar free version!
This is actually one of the first cookie recipes I published on the blog. I have just added step-by-step images and more tips and tricks to the post.
This means I've just had the best day ever. Because I now have a portion of deliciously crunchy, nutty keto walnut cookies sitting right in front of me.

Ingredients
![Ingredients for this recipe, measured into bowls.](https://sugarfreelondoner.com/wp-content/uploads/2022/11/keto-walnut-cookies-ingredients.jpg)
- Chopped walnuts - Make sure they are fresh! I pulsed mine in a food processor. You can also chop them finely with a knife. Or, put them in a plastic bag and crush them.
- Egg - Use either 1 medium egg or 1 large egg white. I tried both and preferred the taste with the whole egg. However, both work well.
- Powdered sweetener - Powdered erythritol, any erythritol blend such as Swerve or monk fruit sweetener, Bocha Sweet, allulose or xylitol. Make sure you are using a 1:1 sugar alternative.
- Cinnamon

Expert Tip
Don't over-process the walnuts! I like to leave some larger chunks. If the walnuts are coarsely ground, the cookies will be crunchier.
However, even if you blend the walnuts to a fine flour accidentally, the recipe will still work. It's quite forgiving.
Recipe FAQs
Yes, walnuts are suitable for a keto diet. They are very low in carbohydrates. 1 ounce (30 grams) or 14 halves of walnut contain just 3.9g of carbs.
Yes, if you don't mind a little grittiness. I have made these cookies with Lakanto Gold, which is a granulated brown sugar alternative.
The egg is the binder in this recipe. You could try a mix of nut butter and flaxseed instead. Also, grind the nuts more finely.
Your walnuts are too coarse. Add a little almond flour or a pinch of coconut flour to fix it.

Variations
Here are ideas how you can change up the recipe.
Use different nuts. The recipe works with any nuts, such as almonds, pecans or hazelnuts. You can also use a mixture. Just don't call them keto walnut cookies 😊
Add butter. 1-2 tablespoons of melted butter gives the cookies a rich, buttery flavor.
Chocolate: Throw in some sugar free chocolate chips or coat the cookies in dark chocolate such as Lindt (90% cocoa solids).
Change the spices: Try vanilla extract or a pinch of salt
Storage
Store in an airtight container for up to 2 weeks. You can keep them either at room temperature or in the fridge.
All low carb cookies freeze well. Store in the freezer for up to 3 months.

A successful recipe! Well, mine was a bit too watery because I didn't want to grind the walnuts to powder. So I added some almond flour like you said. Turned out great! Perfect snack. Thank you Katrin!

I've made these twice - once with original recipe and walnuts, the next time with hazelnuts, substituted 1 tsp cocoa for cinnamon, added tsp vanilla , a shake of cinnamon & added lily choc chips. Both times they were yummy. Thanks!
