As many of you know, a few weeks back I started on my hunt for easy snacks and desserts. By that, I mean recipes that are not overly complicated or time-consuming.
You know what I mean, they had to be easy to make for this busy mom.
Along with those two criteria, I needed them to be amazing enough to satisfy my sweet tooth.
After all, a quick and easy recipe is nothing special unless it is also super tasty, right?
So far in my simple snack recipe series, I have added two recipes to my blog and today I am pleased to introduce you to my third recipe, Lemon Custard Squares.
I am so excited to share them with you guys. I have fallen in love with these and I think I need them on a daily basis.
If only I had a lemon tree at my disposal…ahh…heaven!
They are a great low-carb and gluten-free dessert and thankfully they are some of the easiest lemon squares I have ever made.
How Do You Make Low Carb Lemon Custard Squares?
These Lemon Custard Squares were by my Chocolate Walnut Bars. You might have seen those, they were the first recipe in this new easy snack kick I am writing about.
Those bars are amazing and they remind me of a rich and velvety chocolate pie but only so much easier to make!
When those bars turned out so well and some of you guys started letting me how much you liked them I knew that I needed to expand on the flavors of these easy cookie bars or square-type desserts.
After all, I know that some people are not as crazy about chocolate as I am. No, I simply can’t imagine that, but it is true!
Even though chocolate is one of my “love languages”, I do like to branch out from time to time and enjoy fruity flavors so I am super excited to offer these Lemon Custard Bars as an alternative to my chocolate version. They are just as good and a nice break from chocolate from time to time.
Did I admit that?
To Make These Custard Bars You’ll Need:
Lemon Juice
Lemon Zest
3 Eggs
Your Favorite Erythritol Sweetener
Your Favorite Low-Carb Baking Mix
Butter
With just these few ingredients you will have the workings of a lovely dessert. If you love lemon then these bars are the place to be!
The best part is they really couldn’t be simpler! Even if you aren’t the best of bakers this recipe will turn out great! Trust me,
So the next time you are craving some sweets and you don’t feel like making anything complicated you should give these Lemon Custard Squares a try.
There are only a few steps to making these heavenly squares and like many of my recipes, the hardest part is waiting for them to chill.
But oh are these so worth the wait, that perfect pucker with all the right sweetness!
I promise you no matter your baking skills these bars will come together so simply and they will have your taste buds doing the happy dance!
The Lemon Squares are the perfect dessert with your low-carb meals or if you follow THM they are a great “S” meal snack.
They are low-carb and gluten-free but you will feel like you are cheating with these little squares.
It was so hard for me to stop at one…or was it two?
Lemon Custard Squares
Deliciously sweet and tart lemon custard baked on top of a tender and buttery cookie crust.
Ingredients
For the Crust
- 1 cup of Trim Healthy Mama Baking Blend*
- 7 tablespoon of softened butter
- 1/4 cup of Trim Healthy Mama Super Sweet (or 1/3 cup Erythritol Blend of choice)
- 1 teaspoon lemon juice
For the Lemon Filling
- 1/3 cup of lemon juice
- 1/3 cup of THM Super Sweet (or 1/2 cup Erythritol Blend of choice)
- 4 tablespoons of butter
- 3 large eggs, beaten
- 1 teaspoon fresh lemon zest
- 1 tablespoon of powered sweetener of choice for dusting (optional)
Instructions
- Preheat your oven to 350.
- Line an 8x8 baking pan with parchment paper and spray the paper with cooking spray. Set the pan aside and prepare the cookie base.
- Add the dry ingredients for the cookie base to your mixing bowl and add the softened butter and lemon juice then mix until the mixture comes together into coarse crumbs and stays together when pinched between fingers.
- Next press the cookie mixture into the bottom of your paper-lined pan. Make sure you spread the mixture evenly and press it into the pan well.
- Bake in the preheated oven for 10-12 minutes.
As the base is baking add the lemon juice, sweetener, butter, lemon zest to a saucepan over low heat. Cook the mixture whisking frequently. Do not boil. - Remove the lemon mixture from the heat and let it cool for 5 minutes.
- Crack 3 eggs into a bowl and beat before slowly pouring in the lemon mixture while whisking the whole time until all the lemon mixture is combined.
- Remove the cookie base from the oven after it is baked and pour the lemon mixture over the base. Spread the mixture out as evenly as possible.
- Return to the oven and bake for 18-20 minutes or just until the lemon custard is set.
- Cool the Lemon Cookie Bars on a wire rack completely then place them in the refrigerator to chill for at least one hour. The longer these Lemon Custard Squares chill the better they get!
- Once chilled remove the bars from the baking pan and dust with the powdered sweetener if desired.
- Cut the Lemon Custard Squares into 15 squares and serve or store in an airtight container in the refrigerator.
Notes
Crust Modifications: If you do not have the THM Baking Blend you can use a combination of 3/4 cup almond flour and 1/4 cup oat fiber for the crust. Depending on the absorbency of the brand of oat fiber you use you may need a bit more butter to bring the crust together. Note: the nutrion

This is my second time making these they were such a hit the first time with my hubby he said it is his favorite sweet treat so far! I waited 5 minutes before adding the beaten eggs and so far they have been just perfect in the mixture. Thanks for sharing the recipe!!
Keri Bucci says
I’m so glad to hear they are a hit, Peggy!
Julie says
The first time I made this, I put the butter, sweetener and lemon in the pot at the same time and the butter hardened when I mixed it with the eggs – it was still good just looked different. The 2nd time, I melted the butter by itself first, then added the sweetener and finally the lemon juice. I made sure the eggs were at room temperature and it came out beautifully. Great recipe, thank you for sharing.
Keri Bucci says
Thank you, Julie! I appreciate you coming and sharing what worked well for you. So glad you enjoy the recipe!
Kim says
I have made these several times now and they are amazing! Lemon bars were always a favorite for me, so just imagine how thrilled I am to have a Sugar-Free, white flour-free version of this classic dessert bar! You have given me such a gift! Thank you!
Keri Bucci says
Aww, you don’t know how happy that makes me Kim! I’m so very glad you can enjoy on of your favorites. Thank you so much for trying them out and letting me know how much you like them!
Jennifer says
How much pure monk fruit can be used instead of super sweet or erythritol? Thanks!
Keri Bucci says
I’ve never used Monk Fruit Sweetener Jennifer so I’m sorry to say I’m not sure.
Donna says
I love lemon & this sounds delicious! How long do we cook the lemon mixture before removing from heat & letting it cool for 5 minutes?
Keri Bucci says
Basically just to get it warm enough so that the sweetener melts, you don’t want it to be grainy, so just a few minutes on low to medium heat, no need to boil or simmer.
