Easy Keto Cheesecake Bars
I think cheesecake is an amazing dessert. First, there is a chewy or crunchy crust. There’s a rich, decadent filling. There’s usually a topping of some sort. What more could you want? These keto blueberry lemon cheesecake bars are one of my favorite ways to make cheesecake. Sweet blueberries and tart lemons are a perfect match. They go so well with the richness of the cream cheese. But the recipe doesn’t stop there. It also has a coconut crumble topping!
This might sound gourmet. And it definitely tastes gourmet. But it takes less than an hour to make. And because these are bars, it’s a great dessert to bring to a party or potluck.

How to Make Gluten-Free Cheesecake Bars
Here’s how to make the fruity keto dessert. It’s super easy!
- Make the sauce. Add the blueberries, Swerve confectioners sweetener, and water to a saucepan. Simmer until the sauce becomes thick. This should take 10-15 minutes.
- Preheat the oven. Turn the oven on to 350F.
- Prep a pan. Line an 8×8-inch pan with parchment paper or aluminum foil.
- Make the crust. Add the melted butter, almond flour, and Swerve sweetener to a bowl, and stir to combine. Press the mixture into the pan.
- Prebake the crust. Bake the crust until it just starts to brown. This should take about 7 minutes.
- Chill the crust. Remove the crust from the oven and let it cool.
- Make the filling. Use an electric mixer or a blender to combine the cream cheese, egg yolk, lemon juice, lemon zest, vanilla extract, and Swerve confectioners sweetener into a smooth mixture. Spread it over the crust.
- Add the sauce. Spoon the blueberry sauce over the top of the cheesecake.
- Make the crumble. Put the butter, almond flour, coconut flakes, and Swerve sweetener in a food processor or blender. Blend until it has the consistency of crumbs. Sprinkle over the cheesecake.
- Bake. Bake the cheesecake until the top is slightly browned. This should take 18-20 minutes.
- Chill. Allow the cheesecake to cool, then slice it into bars.
Tips for Success
Here are a few tricks and tips for making these tangy cheesecake bars.
- Use room temperature ingredients. For the best results, use butter, cream cheese, and egg yolks that are at room temperature. When these ingredients are at room temperature, they’ll better mix with the other ingredients. That makes the cheesecake much more smooth.
- Let it cool. Make sure to let the cheesecake crust fully cool before adding the filling. Otherwise, the cheesecake will become a funny texture. Also, make sure to let the finished product cool fully before cutting it. That allows the bars to firm up.
- Freeze it briefly. For the best-looking cheesecake bars, put the cheesecake in the freezer before cutting it. After 15 minutes, take the cheesecake out, and cut it into bars. This will make the slices much cleaner.
How to Store Leftovers
You can keep these keto blueberry lemon cheesecake bars in the fridge for up to 5 days. Just make sure to store them in an airtight container.
Can I Freeze This Keto Dessert?
Yes! I love to keep these bars in the freezer. Wrap the keto dessert in plastic wrap, and then place it in an airtight container or bag. They’ll last in the freezer for 3 months. Thaw at room temperature, or in the fridge overnight.

Hello, is it 5.5 net carbs for each bar or for the whole thing ?
Can you freeze these?
Yes it worked wonderfully
I don’t like coconut at all. Any recommendations on a substitute?
Laurie riordan says
Loved this recipe it was absolutely delicious
I love this recipe and it was good in spite of my crust being crumbly without form. Any recommendations. Happened twice. It’s like it needs something to make it more firm? New to using the almond flour, but would love to learn more to eat more healthy. Thanks in advance for your concern.
Hi Renee, are you sure you are using the right size pan? If using an 8×8 pan and patting the crust down it is a pretty thick buttery crust layer and I never have issues crumbling. If you are using a larger pan and making it thinner that may be your problem.
The keto blueberry lemon bars are the best keto dessert I have found in two years on keto. Delicious!
It’s the b8 tablespoons of butter supposed to be melted or softened? My crust before baking is like a batter – no pressing into the pan but spreading.
Sonya, the butter is melted. Press or spread it into the bottom of the 8×8 baking dish and pre-bake then cool completely before moving on to the next step.
Just making sure, are these gluten free as well?
Yes, they sure are!
Is the butter suppose to be melted for e crumble? Mine came out for like dough then a crumble…
No it is not melted, it is pulsed together in a blender for a crumb topping.
These blueberry cheesecake bars are divine!
At first my crust was batter like as well—like Sonya above mentioned. So I dolloped into the pan & spread it out. It seemed as if much of the melted butter rose to the top, so I sifted a light layer of almond flower to absorb it. I usually prefer to weigh my ingredients as that is more accurate for me but I had no idea how much to use without that reference, so I measured the almond flour by very lightly spooning the flour into the measuring cup, then leveling off!
I put it in the oven for 8 minutes. it wasn’t beginning to brown yet so I left it in , got busy with the filling & forgot about it—yikes! A bit dark, but definitely not burned! I allowed it to cool & assembled anyway, then baked.
It is still delish! My husband loved it, too! Thank you so much for this fabulous recipe!
Other than lightly sifting more almond flour onto the crust the only other substitution I wade was the sweetener. I used Allulose instead of Swerve and I ground it in my coffee grinder to powder it for the filling.
Just curious about the method you use to measure into your cups—do you scoop & level or drop by spoonfuls into cup & level?
Thank you again for an extraordinary recipe! I’ll be checking out more of them!
Two questions on substituting-
1. Can I sub strawberries for the blueberries?
2. Any suggestions for subbing the coconut in the crumble?
These look amazing, and I would love with the blueberries, but I want to make these for my sister and I think she’s not a huge fan of blueberries.
Hi Nicole, I haven’t used strawberries specifically but I’ve done this with blueberries, raspberries and cranberries so I imagine the strawberries would work just fine. As for the crumble you can use the Pecan Crumble from these Cranberry Cheesecake Bars
2 tablespoons butter
1/4 cup pecans
1/2 cup almond flour
1 tablespoon Keto friendly confectioners sweetener such as Swerve or Monkfruit
I hope this helps!
can I use frozen blueberries?
That should work fine.
Can you use frozen blueberries?
