- 2 large eggs

- 2 tablespoons lemon zest

How to Make Keto Lemon Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that the bars bake evenly.
Step 2: Prepare the Baking Dish
Line a 9×9-inch baking dish with parchment paper, leaving some overhang. This makes it easier to remove the bars once they are set.
Step 3: Make the Crust
In a mixing bowl, combine the almond flour, melted butter, erythritol, and salt. Mix until the mixture resembles wet sand.
Step 4: Press the Crust
Press the crust mixture evenly into the bottom of the prepared baking dish. This creates a sturdy base for the lemon filling.
Step 5: Bake the Crust
Bake the crust in the preheated oven for 10 minutes until lightly golden. This pre-baking helps to firm up the crust.
Step 6: Prepare the Filling
In a separate bowl, whisk together the eggs, lemon juice, lemon zest, erythritol, and baking powder. This creates a smooth and tangy filling.
Step 7: Pour the Filling
Pour the filling over the baked crust evenly. Make sure to spread it out for an even texture.
Step 8: Bake the Bars
Bake the bars for an additional 15-20 minutes until set. The filling should be slightly firm and not jiggly.
Pro Tip: Let the bars cool completely in the pan before slicing for clean edges.
Tips for the Best Keto Lemon Bars
- Use fresh lemon juice for the best flavor; bottled juice can be too acidic.
- For a more intense lemon flavor, increase the zest.
- Let the bars chill in the fridge for a few hours for a firmer texture.
- Dust with powdered erythritol before serving for a beautiful presentation.
- Feel free to add a pinch of turmeric for a vibrant color without affecting flavor.
Common Mistakes to Avoid
- Not pre-baking the crust can lead to a soggy bottom.
- Using old lemons may result in a bland flavor.
- Overbaking can cause the filling to crack; keep an eye on it.
- Not letting the bars cool completely can make slicing difficult.
Serving Suggestions
These keto lemon bars are delightful on their own, but they shine even more with a few pairings.
- Serve with a dollop of whipped cream or coconut whipped cream.
- Pair with fresh berries for a burst of color and flavor.
- Enjoy alongside a cup of herbal tea for a relaxing afternoon treat.
- Top with a sprinkle of toasted coconut for added crunch.
Variations to Try

- Mix in some poppy seeds for a fun texture.
- Top with a layer of sugar-free chocolate ganache for a decadent treat.
