How to Make LOW CARB LEMON BARS
Step 1: Preheat and Prepare Your Pan
Start by preheating your oven to 350 degrees Fahrenheit. This ensures that your bars bake evenly. While that’s heating up, grab a 9×9 square baking pan and prepare it with nonstick cooking spray so that your delicious creation doesn’t stick!
Step 2: Make the Crust
In a mixing bowl, whisk together the almond flour and powdered erythritol until well combined. Then, stir in the melted butter until you have a crumbly mixture. Press this mixture firmly into the bottom of your prepared pan; this will form a delightful base that holds all that zesty filling!
Step 3: Bake the Crust
Pop the pan into the preheated oven and bake for about 15 minutes. Once it’s done, remove it from the oven and let it cool slightly—this step is key as it helps maintain structure when you pour on the filling.
Step 4: Prepare the Filling
In a food processor, blend together the eggs and granulated sweetener until smooth. Add in fresh lemon juice, baking powder, and coconut flour; pulse again until everything is nicely combined. This creamy mixture will become your luscious topping!
Step 5: Final Bake
Pour the filling over your cooled crust. Bake everything together for another 20 minutes or until you see that lovely center has set up nicely. It’s important not to overbake; you want those bars to stay tender and soft!
Step 6: Cool and Serve
Once baked, allow your lemon bars to cool completely before slicing them into squares. If desired, sprinkle some additional powdered erythritol on top for an extra touch of sweetness! Enjoy every tangy bite!
Pro Tips for Making LOW CARB LEMON BARS
Making the perfect low carb lemon bars can be a breeze with just a few helpful tips!
- Use room temperature eggs: This ensures they blend more easily, creating a smooth filling that bakes evenly.
- Sift your sweeteners: Sifting powdered erythritol helps eliminate lumps, resulting in a smoother texture for both the crust and filling.
- Don’t skip cooling time: Allowing the bars to cool completely before slicing helps them set properly, making for cleaner cuts and better presentation.
- Adjust sweetness to taste: Everyone’s palate is different; feel free to tweak the amount of erythritol based on your personal preference for sweetness.

FAQs
Can I make LOW CARB LEMON BARS without almond flour?
Yes, you can substitute almond flour with coconut flour, but remember that coconut flour is more absorbent. Use only about 1/4 cup of coconut flour instead of 1 1/2 cups of almond flour.
How do I know when my LOW CARB LEMON BARS are done baking?
The lemon bars are done when the center is set and no longer jiggly. A toothpick inserted should come out clean or with just a few moist crumbs.
Can I use another sweetener instead of erythritol?
Absolutely! You can substitute erythritol with monk fruit sweetener or any low-carb sweetener of your choice, just ensure it’s suitable for baking.
