Keto Lemon Bars Ingredients
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 give structure.
- 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
- 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.
- 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 with tons of powdered sweetener!
- Use powdered sweetener – I mentioned it above and I mention it here! It’s vital to use some sory of sweetener turned into powder if you want creamy lemon bars.
