I have been thinking about making a keto version of Lemon Lush for several years. And now that I have made it and tasted it, I wonder why on earth I waited so long. This is creamy, dreamy, lemon scented heaven!

And it’s an absolutely spectacular way to showcase keto lemon curd. Sandwiched between a layer of keto cheesecake and some whipped topping? Oh baby! It’s the dream dessert for lemon lovers.

You have to try this!

This is a recipe that goes by many names. I’ve seen it called Lemon Delight as well as Lemon Lasagna. And since it’s the lemon version of my keto sex in a pan, it could arguably go by that name as well.

Whatever you call it, this keto lemon dessert is the stuff of dreams. And while it has multiple layers and steps, it’s also easy to make. The hardest part is waiting for everything to set properly.

I had a lot of fun making this as a no-bake dessert by using HighKey Vanilla Wafers for the crust. I ground them up in my food processor and mixed them with melted butter. But you could use other cookies or you could make the crust from scratch. Check out the Expert Tips section for more ideas.

I originally intended for this Keto Lemon Lush to serve 16. But it turns out that it’s so low carb, you could easily cut it into 12 instead. And each piece would still only have 2.1g net carbs!

Keto cookies: I used the HighKey Vanilla Wafers for this crust but you can use any crisp keto cookies, either store-bought or homemade. See Expert Tips for more options.
Cream cheese: Make sure your cream cheese is well softened before beating.
Sweetener: I recommend Swerve Confectioners for the cheesecake and the whipped topping. Check out the Expert Tips for more sweetener options.
Lemon juice: Freshly squeezed lemon juice will provide the best flavor.
Lemon curd: Make a batch of my Sugar Free Lemon Curd for the ultimate tangy flavor.
Whipping cream: Most lush recipes take pre-packaged whipped topping. But it’s so easy and so much tastier to make your own whipped cream!
Pantry staples: Butter, vanilla extract.

Step by Step Directions

A collage of 6 images showing how to make Keto Lemon Lush.

1. Crush the cookies: Place the vanilla wafers in a food processor and process until they resemble crumbs. You can also crush them in a ziplock bag.

2. Make the crust: Transfer the crumbs to an 8×8 inch pan and drizzle with the melted butter. Mix well to combine and then press firmly and evenly into the bottom of the pan. Freeze will preparing the filling.

3. Prepare the cheesecake: In a large bowl, beat the cream cheese until smooth, about 2 minutes. Beat in the sweetener and lemon juice until well combined. Add the cream a little at a time until a nice spreadable consistency is achieved. Spread over the chilled crust and return to the freezer.

4. Spread the curd: Prepare the lemon curd according to the directions, if you haven’t already. Spread over the cheesecake filling and return to the freezer.

5. Whip the cream: In a large bowl, beat the whipping cream with the sweetener and vanilla until it holds stiff peaks. Spread over the lemon layer and return to the freezer. Freeze at least 2 hours to help it set before cutting into servings.

Expert Tips

I recommend preparing the keto lemon curd in advance, to streamline the process. You can make it up to 2 days in advance and store it in the refrigerator until ready to use. Many readers love it so much, they keep some on hand at all times!

Freezing the dessert at each step of the process helps firm each layer faster. 20 to 30 minutes should be sufficient between layers, and then 2 hours in the freezer after the dessert it complete.

Crust options: There are so many fun ways to make this crust. If you use pre-made keto cookies, make sure they are crisp rather than soft-baked. The Mini Lemon Cookies from HighKey would be perfect for this.

For homemade options, try Keto Graham Crackers or Butter Pecan Cookies. You could also simply make a shortbread from scratch and bake it, similar to these Keto Lemon Cheesecake Bars.

Sweetener options: You can use a number of sweetener here but I do find that using allulose makes the cheesecake filling and the whipped topping very soft. They don’t firm up as well and the pieces come out a little messier. But it does work!

Since this is not a baked recipe, make sure you are using sweeteners that dissolve well. I recommend powdered sweeteners like Swerve Confectioners or concentrated liquid sweeteners like stevia extract.

Frequently Asked Questions

Are lemons keto friendly?

Lemons are a relatively low carb citrus fruit and can be used in keto recipes. Half a cup of fresh lemon juice has 10 g of carbs and 3g of fiber. But one rarely consumes half a cup of lemon juice in one sitting, so the carbs are much lower when spread out over a number of servings.

How many carbs are in Keto Lemon Dessert?

This delectable low carb lemon lush recipe has 3.7g of carbs and 1.6g of fiber per serving. That gives it a net carb count of 2.1g per slice.

Can you freeze Lemon Lush?

You can store Lemon Lush in either the refrigerator or the freezer. In both cases, wrap it up tightly. It can last in the refrigerator for up to 5 days or the freezer for up to 2 months. Let it thaw completely before serving.
