Keto Egg Fast Lemon Bars


Low Carb egg fast lemon cheesecake bars

Keto Egg Fast Lemon Bars

This fantastic cheesecake type recipe for Egg Fast Lemon bars originally came from a couple of group members in the Egg Fast Stall Breaker facebook support group.

I tried it and I loved it but my big issue with it was the egg to fat ratio.

For followers of the Egg Fast, this is important because it’s so easy to lose track of how many eggs vs how many fats, which is a vital component of the Egg Fast.

Also, the original recipe called for 1 oz cheese for each egg and I think people get better results on this fast with less cheese.

So I have tweaked the recipe to end up with not only using one half the amount of cheese, but also keeping with the 1 egg to 1 tbsp fat ratio.

You can also make these Egg Fast Lemon Bars completely dairy free!

Changing up the Egg Fast Lemon Bars

Ok, there’s lots of things you can do here! Check out the Lime Bars I made for St. Patrick’s Day!

Here are a few variation ideas to change the flavor:

  • The True Lemon Crystals now come in other flavors like Lime and Orange
  • Omit the sweetener and use one of the allowed Skinny Mix sugar free drink mixes to flavor the bars. My favorite is Caramel Pecan!
  • Instead of True Lemon crystals make use of extracts like Maple, Rum, Banana, Coconut, etc. I’m very intrigued by these flavor sets but they don’t ship to Canada.
  • You can make this completely dairy free by substituting coconut oil for the butter and 1 tbsp mayonnaise for each ounce of cream cheese.

Have fun and see what variations you can come up with!

Keto Egg Fast Lemon Bars - These taste like cheesecake!>

  1. I can’t believe how good these are. I don’t like eggs…and I really don’t like baked eggs but these came out the perfect texture! Today is my last day of an egg fast and this all I’ve eaten ( it’s been hard for me to get 6 a day 😩) I wonder if can I make these savory… like egg bites… previous attempts at egg bites have resulted in a terrible texture! I’m going to try! Thanks so much. BTW I used cream cheese, lakanto (a bit extra actually), and extra lemon packets, I like it tart!🍋

  2. How much skinny girl syrup would you use do you think? I mad a batch with lemon crystals and they are so delish. I want to play around with some flavors. Thank you for such a great recipe.

    1. I would start with 2 tbsp and dip your finger into the batter to test the sweetness. For me, the Skinny syrups go a long way and I tend to use way less of them but others might have a sweeter taste than I do.

    1. I have actually never tried it with lemon juice because these are egg fast bars and no lemon juice on the egg fast. If you are just doing these on regular keto then sure, give it a try!

      1. One of the ingredients in the lemon crystals is lemon juice so I don’t really understand why you could t use the lemon juice (during egg fast). Just curious…plus I don’t have any crystals. 😄

        1. Can you get lemon extract? The reason that the crystals are preferred is twofold. For one, they offer zero carbs while there is 1 carb in every tbsp of lemon juice and it takes a few tbsp of lemon juice to get the same lemony flavor as from the crystals. The second reason, is the amount of liquid added by the juice as opposed to the crystals (or extract). But if it’s all you have then keep it to a minimum and see how it goes!

  3. How long can you store these in the fridge if you wanted to make enough (in different flavors) for a few days?

    1. I would say up to a week. It’s similar to how long you could keep a cheesecake in the fridge.

    1. The protocol calls for up to 4 ounces of cheese daily and so cream cheese is a cheese. It is optional so if it goes against your own goals or desires then it can be left out.

  4. How would you adapt the recipe for Lemon extract? If the recipe calls for 4 packets of lemon crystals, how much does this equate to for amount of lemon extract? I would love to make this! Thanks!

    1. Lemon extract can be quite strong so here’s what I would do. Put in 1/2 tsp, mix it up and then dip your finger in and taste. If it’s not lemony enough then add more. I’ve made it with lemon extract before but I don’t remember exactly how much I used so I don’t want to say too much and then have you not like it! Good luck with it!
