- ½ teaspoon vanilla extract
- Pinch of salt
For the creamy lemon filling:
- 4 ounces softened cream cheese
- 3 large eggs

- 1 teaspoon vanilla extract
- ¼ cup heavy cream
Optional toppings:

🔪 How to Make Keto Creamy Lemon Squares
1️⃣ Prepare the Almond Crust
Preheat your oven to 350°F (175°C).
Line an 8×8 pan with parchment paper.
In a bowl, mix:
- Almond flour
- Melted butter
- Sweetener
- Salt
- Vanilla
Stir until the mixture forms a sandy, cohesive dough.
Press the crust evenly into the baking pan and bake for 10 minutes until lightly golden.
Let cool slightly before adding the filling.
2️⃣ Make the Creamy Lemon Filling
In a mixing bowl, beat the softened cream cheese until smooth.
Add the eggs one at a time, mixing well.
Stir in:
- Sweetener
- Lemon juice
- Lemon zest
- Vanilla
- Heavy cream
The mixture should be smooth, creamy, and pourable.
3️⃣ Pour and Bake
Pour the filling over the pre-baked almond crust.
Bake for 18–22 minutes, or until the center is set but still slightly jiggly.
Avoid overbaking—this keeps the filling silky.
4️⃣ Cool and Chill
Let the lemon squares cool at room temperature for 20 minutes.
Refrigerate for at least 2–3 hours before slicing.
Cold temperature helps the filling set into perfect creamy bars.
5️⃣ Slice and Serve
Lift the chilled slab using the parchment paper.
Cut into clean squares using a sharp knife.
Add a sprinkle of powdered sweetener if desired.
Enjoy chilled for the best flavor and texture.
⭐ Tips for Perfect Keto Lemon Squares
✔ Room Temperature Cream Cheese
This ensures the filling blends smoothly without lumps.
✔ Don’t Skip the Lemon Zest
It adds depth and balances the sweetener.
✔ Bake Just Until Set
Overbaking can make the filling dry.
✔ Chill Before Cutting
Cold squares slice cleanly and hold their shape.
✔ Adjust Sweetness
Keto sweeteners vary—taste the filling before baking.
✔ Use Fresh Lemons
Bottled lemon juice lacks the vibrant, fresh lemon flavor needed.
