Those look amazing! I've been using a similar recipe that is coconut flour, but calls for twice the amount of eggs, they are good, but don't look nearly as fluffy as those do. I'll be trying this one next, thanks for the recipe!
This recipe reminded me, for those looking to get serious about keto, you can find really good substitutes for many of the things you like to indulge in, but expect to pay a bit more, as the almond flours and coconut flours are not cheap.
