Keto Lemon Bars – Low Carb & Delicious

keto lemon bars

If you’re trying to watch your carbs, but you can’t let go of desserts, these keto lemon bars are sure to hit the spot. You’ll love the chewy, tangy, and perfectly sweetened taste of these bars. They are so delicious that you will feel like you are eating the real ones.

The best part is that this recipe for keto lemon bars from Joe Duff is made with only six keto-friendly ingredients. You might even have all those ingredients already sitting in your kitchen so there won’t be any need to make a special trip to the supermarket.

Recipe notes 

Alternative low carb flours

You can use other low carb flours such as walnut flour or sunflower seed flour if you like. I must say that I’ve never tried baking with either of these flours have you? I must give one of them a try.

If you are going to use one of these flours in this recipe you can just use it in the same quantity as the almond flour.

Reduce the carbs 

Each bar contains about 2.5 net carbs but if you want to reduce the carbs even more you could substitute some of the almond flour for zero carb unflavored whey protein powder.

If you decide to do this then you should use 1 gram of protein powder for each 1.5 grams of almond flour.

Organic lemons 

I have slightly tweaked the recipe to include organic lemons. While they are not on EWG’s Dirty Dozen List, citrus fruits are sprayed with pesticides and as lemon zest is needed for the recipe it’s best to avoid any pesticide residue on the skin.

If you are unable to buy organic ones then try to find unwaxed lemons at least. You don’t want the wax either! While some of the waxes used on lemons are natural some are derived from polyethylene, a type of plastic.
