    Keto Lemon Bars With Only 2 NET CARBS

    Published: May 8, 2021 · Modified: Feb 17, 2022 · By: Joseph Duff

    Jump to Recipe

    These keto lemon bars are the ultimate pick-me-up. They're sweet, tangy, and silky smooth with a buttery shortbread crust and sugar free powdered sugar topping. And each one is so melt-in-your-mouth delicious that you'd never guess it has just over 2 NET CARBS!

    THE BEST KETO LEMON BARS

    Calling this keto lemon bar recipe addictive is an understatement.

    Between the crisp shortbread crust, refreshing and creamy lemon filling, and the fact that each piece literally has just over 2 NET CARBS, I can never eat just one!

    And, honestly, I find myself making these little bites of sunshine a lot lately. But it's not just because they're low carb lemon bars and are the perfect dessert for the warmer weather - but because my friends and family can't get enough of them! 

    Seriously, every time someone comes to my house, they ask if I have any lemon bars - that's how good they are.

    So it helps that they're quick and easy to make - you'll only need about 30 minutes to whip them up! 

    Plus, this recipe uses super common keto pantry staples, which means you can start as soon as, well, NOW.

    INGREDIENTS FOR KETO LEMON BARS

    Once again, you only need a few staple baking ingredients to make these keto friendly lemon bars. And odds are you have most of them in your kitchen already.

    Here's what you'll need to make the crust:

    • 1 cup almond flour
    • ¼ cup coconut flour
    • Just over 5 ½ tbsp. butter, softened
    • 2 egg whites (or 1 egg)
    • ¼ cup confectioners swerve

    And to make the filling:

    • 8 egg yolks + 1 egg (or 2 egg yolks and 3 eggs)
    • ½ cup lemon juice
    • Zest from 1 lemon
    • ½ cup confectioners swerve
    • 1 tablespoon coconut flour
    • 3 tablespoon butter

    What did I tell you, pretty simple stuff, right?

    And if you like refreshing lemon desserts, you can use many of the same ingredients to make my keto lemon pound cake next!

    It's another low carb take on a classic lemony dessert that I'm sure you'll love.

    DIVING INTO THE INGREDIENTS

    So, we'll be using both almond flour and coconut flour for this recipe.

    Now, if you're allergic to almond flour - or it's just isn't your thing - don't try to substitute almond flour with more coconut flour.

    In a small amount, coconut flour gives these lemon bars that slight melt-in-your-mouth crumble that makes them so satisfying to eat. However, any more of it, and you'll end up with overly dry and crumbly lemon bars since coconut flour is super absorbent. 

    Instead, you can substitute the almond flour with an equal amount of sunflower seed flour or walnut flour. Both are keto friendly flours and will work just as well in these lemon bars. 

    Another way we will keep this recipe keto friendly is by making sugar free lemon bars - yep, that's right, we won't be adding any sugar to our bars.

    So, to balance out the rich and tangy flavors in the lemon bars, we'll be using Confectioners Swerve - which doesn't have any carbs/calories - for the crust and filling instead of sugar.

    If you want another great option, you can use Lakanto's Powdered Monkfruit Sweetener. Like Swerve, it has virtually 0 carbs, 0 calories and tastes exactly like regular sugar.

    HOW TO MAKE KETO LEMON BARS

    As I mentioned, it only takes 30 minutes to whip up these addictive keto lemon bars.

    Plus, you don't need any fancy equipment or techniques, which makes this keto dessert even easier to whip up. 

    Ready? Let's dive into the recipe!

    And overhead view of three rows of three lemon bar squares. The lemon bars are on a piece of white parchment paper and they are covered in powdered sugar.

    Step 1: PREPARING THE CRUST

    Ok, so the first thing you'll want to do is preheat the oven to 350°F (175°C).

    Then, take out an 8x8 inch baking dish and line it with parchment paper.

    Now, mix all the crust ingredients – your flours, butter, egg whites, and confectioners swerve – in a bowl until well-combined.

    Next, pour the crust mixture into the prepared baking dish, forming an even layer on the bottom of the baking dish. Then bake the almond flour shortbread crust for 15 minutes.

    In the meantime, you can start working on the creamy lemon filling.

    Step 2: COOKING THE FILLING

    In a saucepan, combine your egg and egg yolks, followed by the lemon juice, zest, confectioners swerve, and coconut flour. 

    Now, whisk everything together until combined, and cook over medium heat. Then continuously stir the lemon filling until bubbles start to form.

    From there, you should notice the mixture thicken up slightly. So, when you start to see that happen, remove the saucepan from the heat,  add in the butter, and mix until it's melted and fully incorporated.

    Step 3: COMPLETING THE LEMON BARS

    For this next step, you'll want to make sure your crust is still hot from the oven.

    So, while it's hot, you'll want to pour the prepared lemon filling over the hot crust, then put the baking dish back into the oven, and bake for 12 minutes.

    Now, once they're done baking, you'll want to cool them down in the dish, and then you can transfer them to the refrigerator for at least 2 hours to finish cooling/setting.

    Then, when they've chilled, you can slice them into 3 rows and 3 columns to make 9 equally-sized lemon bars. 

    And, lastly, you can finish them off with a generous dusting of confectioners swerve.

    HOW TO STORE YOUR KETO LEMON BARS

    Ok, you made your keto lemon bars, you ate a few, and you loved them. But, now you have some leftovers.

    If this sounds like you, the best way to store any leftovers is in the refrigerator or freezer. And honestly, I think they're even better chilled!

    That said, they can't be stored at room temperature as the lemon-custard filling needs to be kept cool.

    So, to store in the fridge or freezer, wrap the individual squares in wax paper, then again in plastic wrap, and transfer them to an airtight container. They'll stay good in the fridge for up to 1 week or in the freezer for up to 4 months.

    NUTRITIONAL INFORMATION

    If you cut these lemon bars into 9 squares, each one will have just over 2.5 NET CARBS. But, to bring the carb count even lower, you can cut them into even smaller pieces.

    And as far as the rest of the macros go, I think these low carb lemon bars knock it out of the park.

    Here's the full nutritional breakdown for 1 serving:

    • 5.5g Carbs
    • 2.7g Fiber   
    • 2.8g NET CARBS 
    • 6.8g Protein

    Pretty excellent, if I do say so myself.

    There you have it, my special recipe for the ultimate keto lemon bars.  

    Serve them to your family and friends to instantly make their day – and don't forget to save a few for yourself to enjoy throughout the week!
