These Keto Lemon Cheesecake Bars are a zesty treat without the carbs! Creamy cheese and fresh lemons come together on a crunchy crust that’s simply irresistible.
I love these bars because they satisfy my sweet tooth without ruining my diet. Plus, they’re so good, even my friends who aren’t on keto can’t resist! 🍋
Key Ingredients & Substitutions
Almond Flour: This is the star of the crust, giving it a nutty flavor and great texture. If you’re allergic to nuts, you can substitute with sunflower seed flour or coconut flour. Just note that coconut flour absorbs more moisture, so adjustments may be needed!
Powdered Erythritol: This is a keto-friendly sweetener that keeps your bars low in carbs. If you don’t have it, you can use powdered monk fruit or stevia, but remember to adjust the amount as they can be sweeter than erythritol.
Cream Cheese: For a rich filling, softened cream cheese is essential. Neufchâtel cream cheese works well if you want something lower in fat. Make sure it’s at room temperature for easier mixing.
Lemon Juice and Zest: Fresh lemon juice brings brightness to these bars. If you don’t have fresh lemons, bottled lemon juice is a good substitute, but the zest will be missed. It’s best to use real lemons if you can!
How Do I Ensure My Cheesecake Filling is Smooth?
The smoothness of your cheesecake filling is crucial for those perfect bars. Start by making sure your cream cheese is softened, which prevents lumps. Here’s a quick guide:
- Let the cream cheese sit at room temperature for at least 30 minutes before using.
- Beat on medium speed for 1-2 minutes until creamy before adding any other ingredients.
- Add sweeteners and mix until no lumps are left before adding eggs, which helps keep the texture smooth.
- Mix in eggs one at a time to avoid overmixing, which can introduce air and create cracks.
Taking these steps will ensure your cheesecake filling is silky and delicious!

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and another 40 minutes to bake. After baking, you’ll need to let the bars cool before refrigerating them for at least 4 hours or overnight. So, overall, you are looking at approximately 5 hours and 15 minutes from start to enjoying these delicious bars.
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 325°F (163°C). This is the perfect temperature for baking the crust and making sure it gets that lovely golden color.
2. Make the Crust:
In a medium mixing bowl, combine the almond flour, powdered erythritol, melted butter, vanilla extract, and a pinch of salt. Stir everything together until it feels like wet sand. This mixture should hold together when you press it.
3. Bake the Crust:
Press this crust mixture firmly and evenly into the bottom of your lined 8×8 inch baking pan. Bake it in the oven for 10 to 12 minutes, or until it’s slightly golden. Just keep an eye on it! Once done, let it cool while you prepare the filling.
4. Prepare the Cheesecake Filling:
In a large mixing bowl, beat the softened cream cheese for about 1-2 minutes until it’s nice and creamy. Add in the powdered erythritol and keep mixing until there are no lumps and everything is well combined.
5. Add the Eggs:
Add the eggs one at a time, making sure to mix well after each addition. This helps keep your filling smooth and fluffy!
6. Mix in the Flavors:
Now, mix in the sour cream, fresh lemon juice, lemon zest, vanilla extract, and a pinch of salt. Keep mixing until everything is fully incorporated and the filling looks silky smooth.
7. Assemble the Bars:
Pour the delicious cheesecake filling over the cooled crust in the baking pan. Use a spatula to smooth out the top so it looks pretty.
8. Bake the Cheesecake:
Pop the pan back into the oven and bake for 35 to 40 minutes. You’ll know it’s done when the edges are set and the center still has a slight jiggle when you shake it.
9. Cool and Chill:
After baking, take the cheesecake out and let it cool to room temperature. Once cooled, refrigerate it for at least 4 hours or overnight to let it set completely.
10. Cut and Serve:
When you’re ready to enjoy, lift the cheesecake out using the parchment paper overhang. Cut it into bars and enjoy! Feel free to garnish with thin lemon slices or a sprinkle of lemon zest if you’d like.
And there you have it—creamy and tangy Keto Lemon Cheesecake Bars that are sure to brighten your day! 🍋 Enjoy!
Can I Use a Different Sweetener?
Yes! If you prefer not to use erythritol, you can substitute with powdered monk fruit or stevia. Just make sure to adjust the quantity, as some sweeteners can be sweeter than others.
How Do I Store Leftover Cheesecake Bars?
Store any leftovers in an airtight container in the refrigerator for up to 5 days. If you want to keep them longer, you can freeze the bars for up to 3 months. Just thaw in the fridge before enjoying!
Can I Use Cream Cheese Substitutes?
If you’re looking for a lower-fat option, you can use Neufchâtel cheese instead of cream cheese. However, for a dairy-free option, try using coconut cream, but keep in mind the flavor and texture will change slightly.
What If the Cheesecake Is Still Jiggly After Baking?
A slight jiggle in the center is actually normal. It will firm up as it cools and chills in the refrigerator. Just make sure the edges are set before taking it out of the oven.
