Lemon Juice
Fresh lemon juice gives the filling its bright and refreshing citrus flavor. Fresh juice always provides the best taste.

Eggs
Eggs naturally thicken the filling and create the smooth creamy texture.
Sweetener
Granulated sweetener helps balance the tart lemon flavor while keeping the bars perfectly sweet.
Step-By-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Line an 8×8-inch baking dish with parchment paper to make removal easier after baking.
Step 2: Make the Crust
In a mixing bowl, combine:
- Almond flour
- Melted butter
- Granulated sweetener
Mix until a crumbly dough forms.
Press the mixture evenly into the prepared baking dish to form the crust layer.
Step 3: Bake the Crust
Bake the crust for 10–12 minutes or until the edges become lightly golden.
Remove the crust from the oven while preparing the filling.
Step 4: Prepare the Lemon Filling
In another bowl, whisk together:
- Eggs
- Lemon juice
- Lemon zest
- Sweetener
Whisk until the mixture becomes smooth and fully combined.
Step 5: Add the Filling
Pour the lemon filling evenly over the warm crust.
Spread carefully if needed.
Step 6: Bake Again
Return the dish to the oven and bake for another 15–18 minutes.
The filling should look set with only a slight jiggle in the center.
Avoid overbaking to keep the filling soft and creamy.
Step 7: Cool and Chill
Allow the lemon bars to cool completely at room temperature.
Refrigerate for at least 1 hour before slicing.
Chilling helps the filling fully set and creates clean slices.
