I’m a huge chocolate fan, and I bet you are too. But sometimes I crave a delicious summer lemony treat that I always bring to family gatherings. Nobody ever figures out that they are sugar-free, gluten-free, and keto dessert.

Only 7 Ingredients Sugar-Free Lemon Bars

The ingredients for these keto lemon bars have an almond flour shortbread crust, topped with a divine lemon topping. I’m grateful for almond flour and low carb sweetener because I have to opportunity to bake such delicious treats that everyone loves.

  • Unsalted Butter: Melted Butter is used in the shortbread crust and it’s an essential ingredient making the base buttery and extremely decadent.
  • Sweetener: In this recipe, I use both granulated erythritol and powdered erythritol. It’s essential to use granulated sweetener for the crust and powdered for the lemon filling to make it smooth and creamy.
  • Almond Flour: Almond flour is used both in the crust and the lemon filling because it helps with the texture and structure. I recommend using extra fine almond flour to be sure your lemon bars won’t turn grainy.
  • Vanilla Extract: I use vanilla extract in the shortbread crust to enhance the taste.
  • Salt: A pinch of salt to balance the sweetness is perfect!
  • Eggs: Eggs bind everything together and help the bars
  • Lemon Juice: My suggestion is to use freshly squeezed lemon juice for the best flavor. You can also use lime juice or orange juice (not low carb).

3 Tips to Make The Best Lemon Bars Every Time

  1. Use freshly squeezed lemon juice – For that depth of flavor, I recommend using fresh lemon juice. I know it’s convenient to get bottled lemon juice, but you’ll miss the flavor.
  2. Do not overbake! If you notice cracks on top of the lemon bar it means they are overcooked. But, that’s not a problem, these low carb lemon square recipe still taste incredibly delicious. Just dust them tons of powdered sweetener!
  3. Use powdered sweetener – I mentioned it above and I mention it here! It’s vital to use some sore of sweetener turned into powder if you want creamy lemon bars.
