If you love a zesty bite, these Keto Lemon Cheesecake Bars are just for you! They’re creamy, tangy, and made without sugar, perfect for anyone on a low-carb diet.
These bars have a buttery almond crust that complements the smooth cheesecake filling. I like to keep them in the fridge for a cool treat anytime—yum! 🍋
Key Ingredients & Substitutions
Almond Flour: This is the base for the crust. If you need a nut-free option, coconut flour is a great substitute, but you’ll need to use less (about 1/3 cup) since it’s more absorbent.
Butter: For a dairy-free alternative, try using coconut oil or dairy-free margarine. They work well and keep the crust nice and firm.
Powdered Erythritol: This low-carb sweetener is perfect for keto. You can also use stevia or monk fruit sweetener as alternatives, just adjust the quantity according to sweetness level.
Cream Cheese: Nearly any full-fat cream cheese will do the trick. If you want a lighter version, look for lower-fat cream cheese but be cautious as it can change the texture slightly.
Lemon Juice and Zest: Fresh is best for bright flavor! You can use bottled juice in a pinch, but fresh zest is hard to substitute. If lemon isn’t available, lime can work too!
How Do I Make the Perfect Cheesecake Filling?
The cheesecake filling is the star here, but getting it just right is crucial. Here’s how to achieve smooth, creamy perfection.
- Start with room-temperature cream cheese. This makes it much easier to blend without lumps.
- Beat the cream cheese and sweetener together until fully smooth before adding eggs. This helps create a fluffy texture.
- Add the eggs one at a time, mixing gently. This reduces air pockets, which can cause cracks when baking.
- Incorporate lemon juice, zest, and sour cream last. This keeps your mixture silky and adds that wonderful lemony punch!
How to Make Keto Lemon Cheesecake Bars
Ingredients You’ll Need:
For The Crust:
- 1 1/2 cups almond flour
- 1/4 cup melted butter
- 2 tbsp powdered erythritol or preferred keto sweetener
- 1/2 tsp vanilla extract
For The Cheesecake Filling:
- 16 oz (450g) cream cheese, softened
- 3/4 cup powdered erythritol or preferred keto sweetener
- 2 large eggs
- 1/4 cup sour cream
- 2 tbsp fresh lemon juice
- 1 tbsp lemon zest
- 1 tsp vanilla extract
For The Lemon Topping (Optional):
- 1/4 cup fresh lemon juice
- 1 tbsp powdered erythritol
- 1 tsp gelatin powder dissolved in 2 tbsp warm water
How Much Time Will You Need?
This delicious recipe requires approximately 15 minutes of prep time and about 45 – 50 minutes of baking. After baking, it’s important to chill the cheesecake bars for at least 3 hours to ensure they set properly. In total, expect around 4 hours and 15 minutes from start to finish, including chilling time!
Step-by-Step Instructions:
1. Preheat the Oven:
First, preheat your oven to 325°F (160°C). Take an 8×8 inch baking pan and line it with parchment paper, leaving some paper hanging over the edges. This will help you lift the bars out later!
2. Make the Crust:
In a bowl, mix together the almond flour, melted butter, powdered erythritol, and vanilla extract. Stir until the mixture is well combined and crumbly. Then, press this crust mixture firmly into the bottom of your prepared pan, making sure it is in an even layer.
3. Bake the Crust:
Place the pan in the oven and bake the crust for about 10-12 minutes until it’s set and lightly golden. Once baked, take it out and let it cool while you prepare the filling.
4. Prepare the Cheesecake Filling:
In a large mixing bowl, beat the softened cream cheese with powdered erythritol until it becomes smooth and creamy. Then, add the eggs one at a time, mixing well after each addition. Next, mix in the sour cream, fresh lemon juice, lemon zest, and vanilla extract until everything is fully combined and smooth.
5. Combine & Bake:
Pour the cheesecake filling over your cooled crust, spreading it out evenly. Bake in the oven for 30-35 minutes. You’ll know it’s done when the edges are set and the center is just slightly jiggly but mostly firm.
6. Cool and Chill:
Remove the pan from the oven and let it cool completely at room temperature. Once cooled, refrigerate the cheesecake for at least 3 hours, or until it has set completely.
7. Optional Lemon Topping:
If you want to add a delightful lemon topping, take a small saucepan and combine fresh lemon juice with powdered erythritol. Warm this gently over low heat until the sweetener dissolves. Stir in your dissolved gelatin and let it cool a little.
8. Add Topping & Serve:
Pour the topping over the chilled cheesecake bars and refrigerate again for about 30 minutes to set the topping. Once ready, lift the cheesecake out of the pan using the parchment overhang, cut it into squares, and if you like, garnish each square with a tiny slice of lemon.
9. Enjoy!
Store any leftovers in the refrigerator and enjoy these delicious Keto Lemon Cheesecake Bars chilled. They make a perfect low-carb dessert!
Can I Use a Different Sweetener?
Absolutely! While powdered erythritol is ideal for a keto-friendly option, you can substitute with other sweeteners like monk fruit or stevia. Just make sure to adjust the quantity according to their sweetness levels, as they might differ from erythritol.
How Can I Prevent My Cheesecake from Cracking?
To minimize cracking, ensure your cream cheese is at room temperature before mixing. Beat the mixture gently after each egg addition rather than overmixing and avoid baking the cheesecake at too high a temperature. Lastly, cooling it gradually in the oven with the door slightly ajar can also help.
Can I Make These Bars Ahead of Time?
Yes! These Keto Lemon Cheesecake Bars can be made up to 2-3 days in advance. Just store them in an airtight container in the fridge. The flavors often develop even more beautifully as they sit!
What’s the Best Way to Store Leftovers?
Store any leftover cheesecake bars in an airtight container in the refrigerator for up to 5 days. Refrigeration helps keep them fresh and delicious. If you want to enjoy them chilled, simply take them out right before serving!
