Low-Carb and Keto-Friendly: These lemon bars are made with ingredients that are low in carbohydrates and free of any refined sugars, making them a perfect treat for anyone on a keto or low-carb diet.

Gluten-Free: Almond flour replaces traditional wheat flour, making these bars perfect for those with gluten sensitivities.

3. Key Ingredients for Keto Lemon Bars

To make these keto lemon bars, here’s what you’ll need:

Ingredients Breakdown

Almond Flour: The base of the crust is made from almond flour, which is low in carbs and high in healthy fats.
Butter: Adds richness to both the crust and the lemon filling. I recommend using unsalted butter for better control over the salt content.
Erythritol or Monk Fruit Sweetener: These sugar substitutes are great for keeping the bars sweet without the carbs.
Lemon Juice and Lemon Zest: Freshly squeezed lemon juice gives the bars that signature tartness, while lemon zest enhances the citrusy flavor.
Eggs: Eggs help set the filling and create that smooth, creamy texture.
Coconut Flour: Just a small amount is used to thicken the lemon filling and provide structure.
Vanilla Extract: Adds a warm, aromatic flavor to balance the tartness of the lemon.

Substitutions for Keto Lemon Bars

Butter: If you prefer a dairy-free option, coconut oil can be substituted for butter.
Eggs: For an egg-free option, try using flax eggs or chia seeds mixed with water as a binding agent.
Sweeteners: If you're not a fan of erythritol or monk fruit, stevia or allulose can be used as alternatives.

4. How to Make Keto Low-Carb Lemon Bars

Step 1: Preparing the Crust

Preheat the Oven: Line an 8x8-inch baking pan with parchment paper and preheat the oven to 350°F (175°C). This will make cleanup simpler and stop the bars from adhering.
Mix the Crust Ingredients: In a medium bowl, combine the almond flour, erythritol (or sweetener of choice), and melted butter. Stir until the mixture is crumbly and well blended.
Press the Mixture Into the Pan: Press the crust mixture evenly into the bottom of the prepared pan. The crust should be softly golden brown after 10 to 12 minutes of baking. Take out of the oven and leave to cool a little.

Step 2: Making the Lemon Filling

Whisk the Filling Ingredients: In a separate bowl, whisk together the eggs, lemon juice, lemon zest, sweetener, and coconut flour until smooth.
Pour the Filling Over the Crust: Once the crust has cooled slightly, pour the lemon filling mixture evenly over the baked crust.
Bake the Lemon Bars: Return the pan to the oven and bake for another 20-25 minutes, or until the filling is set and lightly golden around the edges. You can test for doneness by gently tapping the pan; the center should be firm.

Step 3: Baking and Assembling

Cool Completely: Allow the lemon bars to cool to room temperature before cutting them into squares. Refrigerating them for 1-2 hours helps set the filling and improves the flavor.
Serve and Enjoy: Serve chilled or at room temperature with a dusting of powdered erythritol for that classic lemon bar finish.
