    These are so delicious. I love lemon. You can also make them a lot smaller instead of having six you could have 12 smaller ones, that’s a good idea 😊

      It looks like the information is for all 6 cookies. That means approximately 70 calories per cookie (sounds much more reasonable if you view the ingredients) and approximately 6 net carbs per cookie. These look yummy and without any grain, gluten, or sugar, I will try them out.

        It turns out the information is for one cookie. I calculated it myself. See my note below under CindyLu.

        Hi, 40g is the total carbs. Each cookie is 4g net. Hope this helps :)

      First time I've ever used Stevia. Recipe was pretty decent, Stevia has a terrible aftertaste. Id try it again with a different sweetner.

        Allulose powder sweetener is a really good keto alternative especially for baking

          What is the serving size? 423 calories per cookie?

            Hi, if the nutritional information does not look correct then you can report this using the 'report it' link above.

          Is this truly 423 calories per cookie??

            I just made them, and calculated the nutritional information, and it's right for EACH COOKIE. Yeah, pretty crazy. The cookies end up being pretty large, though, and the buttercream is way overkill. It's really just butter and sugar with a hint of lemon (I added 3 more tsp. of lemon juice). If you just eat one cookie and spread 1 tsp of butter on it, you're much better off. That works out to 150 cal / 3g carb / 5g protein / 16g fat.

            I think it’s for the whole batch.
