How to Make Easy Keto Hazelnut Biscuits
The star ingredient is hazelnuts, obviously. It might be more convenient to buy pre-ground ones, but you’ll get a superior flavour if you use skinless roasted whole hazelnuts. If you’re in the UK, get them from Lidl (Alesto) – they are divine.
Put them in a freezer bag, break them up with a meat hammer, then whizz them in a mini blender until powdery. Don’t overdo it or you’ll turn them into nut butter. If you do this step in advance, store your ground hazelnuts in a glass jar, tighten the lid, and leave the jar in a dark place.
As for egg white, it is best when it’s a couple of days old. Which is extremely convenient when you don’t have time, or you’re not in the mood, to bake something immediately. Simply store it in a glass bowl, cover with cling film and keep refrigerated until you’re ready (min 1 day, max 3 days, best 2 days).
Remember to take the egg white out of the fridge and leave it at room temperature for a couple of hours. Whip it with the sweetener to soft meringue peaks, stir in the ground hazelnuts and spoon the mixture over a silicone baking mat. Spread each one out to a disc, and bake.
The best sweetener for this recipe is ERYTHRITOL, as it crisps up your biscuits beautifully.
Spoon equal heaps onto a silicone baking sheet and flatten them a little with the back of a teaspoon.

Just 25 minutes in the oven will create delectable, ‘snappy’ biscuits.
When the cookies come out of the oven, they’ll feel soft and spongy to the touch. Wait 10 minutes before handling them. Then flip them or peel them gently away from the silicone liner, and leave them on a rack to air dry for another 10 minutes before storing them. Store them in a cupboard, uncovered, and they’ll crisp up more over time.
Enjoy!
