Matt grew up eating lemon bars, so naturally we had to make a keto version for old times sake! These Keto Lemon Bars combine the tangy-ness of lemon and the sweetness of a sugar cookie base for the perfect sweet and tart dessert. Make these bars for the holidays or for meal prep and watch them be devoured.
More Keto Bars?
We’ve got plenty of those on our food blog that you can check out, but i’ll do you a favor and list some of our best ones below. The benefit to bars is they are easy to portion out and fit into your macros if tracking is something you like to do. It’s also a great finger food that requires no plates or utensils – less clean up for you!
Make A Simple Cookie Base
A simple cookie base as shown in the video and the recipe below makes the perfect start to any dessert. You can use it in place of a crust for pies, bake it on its own in cookie shape or use it for these keto lemon bars!
Keeping it simple will allow the lemon in this recipe to shine! You also don’t want to cook it all the way when your first bake it stand alone. Since we’ll be baking it a second time once the filling has been added a partial bake will ensure it doesn’t come out dry at the very end!
Don’t Skimp On The Lemon
You don’t want to get just a hint of lemon when you’re biting into a lemon bar. You want to be hit with it and to ensure that you need to use enough lemon.
To make sure you get the perfect sweet to sour ratio you using the lemon juice and zest is essential. The zest gives the bars a fresher taste and makes the lemon flavor pop. The cookie base and use of erythritol and stevia in the filling can be over powering so don’t be scared to use a little extra lemon in the filling.

Notes
This is a great recipe. It tastes just like lemon bars, except the crust a at times reminds you it’s keto. But it’s really good. I had such a bad lunch today and this saved it. I suggest, making sure the crust cools down before pouring the filling in. Otherwise it’ll just spread everywhere. But yeah SO GOOD!
So glad you liked it!
Made this today and it is fantastic!
Made these on Easter for dessert. Such a beautiful way to finish up our meal. So bright and sweet. Next time we want more lemon.
Arg… I could not get my to thicken. WHY? Should i use more gelatin?
well the lemon filling taste fine but was a little thin compared to the crust. The crust on the other hand was like stale bread. Not very tasty, and a little mushy. I think the crust needs improvement and the filling needs to be thicker.
I was wondering if I could use granular monkfruit sweetener in place of the stevia and erythritol..?
Yes you can!
Heads up! Someone has copied your recipe, picture and all.
These were a hit with us and our dinner guests! We’ll definitely be making these again! Thanks for the recipe!
I love these!
You forgot to add the coconut flour into the instructions for the base. I am assuming you just add it to the dry ingredients.
I really love you both im learning a lot
Just finished making these and they are cooling. They look great!
It’s going to be a long wait! 😊
I enjoy your videos, recipes and precious baby!
Thank you!
I’ll let you know!
P.S.
When is our cool I’m going to cut them into 18 pieces rather than nine. It’s a mental preparation so when I’m putting two on my plate and putting two on my plate rather than one.
I’ve gone in the last 28 years from 370 pounds and I am 10 pounds from my goal of 130 pounds. So I’ve lost 230 pounds so far. Can I get my best results since I started on the keto diet.
I read a book about the hidden secrets of cancer. One of the best ways to avoid cancer at all is eating pasture raised meat, eggs and any dairy products. And of course organic vegetables and other items that we should be organic. Expensive? Yes! It’s my entertainment money I use so that I stay healthy and live a long healthy active life!
can i use powdered stevia in lieu of liquid?
Can I use Chia instead of the gelatin? If yes how much? Thank you
Is it granular erythritol or powdered?
Lesley since it’s being baked you can use granular or either
@ Lesley – I believe he said in the video it was granulated erythritol. But as he also said near the end of the clip – read the recipe because Matt kinda wings it on these a bit.
You forgot the erythritol in the filling instructions 😁
Thanks! Just fixed it.
I haven’t made these yet but gonna do it! I started on Keto and finally starting to learn to cook…because I have to. Everyone else is on the SAD diet. Love you two and love the goof ups, I’m a pro at that. lol
Hi Matt and Meghan! I considered going on the KETO plan for quite awhile before I actually started eating KETO two weeks ago, so I’m very new to the plan. It’s been very difficult to actually find out everything I need to know about eating on the KETO plan. Everyone, except for you, requires that I pay an arm and a leg in money, or makes me watch a long video plus buy some expensive pills before they’ll share anything about the plan. I’ve been following you for a couple of months now. Your recipes and the ingredients are so simple and your advice helps me tremendously. Lemon Bars are my favorite and these look delicious! Thank you for this recipe. I hope they taste as good as they look. I’ll know because I’ll definitely try these. Thanks again and please keep up the good work!
You might want to change the pink salt (which is poisonous) to pink Himalayan salt.
Thanks! Made the change.
Could you use xanthium gum in place of beef gelatin?
Papa g youtube has a recipe with xanthan. I going to try both
