These 5 ingredient hazelnut flour cookies are pillowy-soft on the inside, crisp on the outside, and topped with crushed hazelnuts for a wonderful, flavorful crunch! Plus, they are gluten-free, low-carb, and dairy-free too.
When it comes to easy Keto and gluten free treats, you just can’t beat a good cookie recipe.
There are so many variations, you could try a new type of cookie every time you bake! After all, variety is the spice of life.
That’s why I love this hazelnut cookies recipe from Katrin at Sugar Free Londoner! I usually bake with a combination of almond flour and coconut flour. Baking with hazelnut flour added a delicious twist on the classic cookie.
And the chopped hazelnuts on top really make the flavor stand out! I like to add these treats to my holiday cookie platters along with low-carb coconut macaroons.
Keto hazelnut cookies
The recipe is based on a simple Italian cookie called Brutti Ma Buoni, literally “ugly but good”. Katrin made a few switches to bring us a low carb and gluten free recipe for these wonderful Italian hazelnut cookies!
With 0.4 grams of net carbs per cookie, they are the perfect guilt-free indulgence.
What makes this recipe even better is that it only uses 5 ingredients in the batter and comes together in minutes.
You’ll simply whip the egg whites, then fold all the ingredients together. After that, use a spoon to drop the dough onto your baking sheet and bake!
Enjoy these hazelnut cookies with your morning coffee or as an after-dinner dessert. With 0.4 net carbs per cookie and delicious hazelnut flavor, you can’t go wrong!
How to make hazelnut flour
You can buy pre-made hazelnut flour, or you can make your own. The process is very easy.
If your hazelnuts still have skins on them, you’ll want to roast them first. Then, once they’ve cooled, you can easily rub the skins off.
If your hazelnuts do not have skins, then you’re ready to go.
Simply put raw hazelnuts in your blender or food processor and blend for about 10-15 seconds.
You want to be careful that you don’t over-process your hazelnuts. Otherwise, you’ll end up with hazelnut butter. Still delicious, but not what we need for this recipe.
Whipping the egg whites
You may be wondering if you really need to whip the egg whites, or if you can simply mix them in.
I experimented with both to see if it made a difference. I must say, I definitely prefer the cookies with the whipped egg whites.
Whipping them adds air bubbles to your cookie batter. This results in a lighter, fluffier cookie with a softer interior.
So while this step is not absolutely necessary, I would recommend it for more satisfying hazelnut cookies.
Can you make these with a different flour
Another nut flour such as almond flour will work just fine in this recipe. You can replace the nut flour 1:1.
However, the nut flour you use will affect the taste. Both almond and hazelnut flour will have a nutty flavor, but hazelnut is a bit richer and deeper in my opinion.
Between the flours, hazelnut does have more texture to it. That’s why, combined with the whipped egg whites, it produces such a soft and light cookie.
So while almond flour and other nut flours can be used, just keep in mind that the final product will be slightly different.
If you enjoy the taste of hazelnuts, I recommend trying this recipe with hazelnut flour.
