What is Lemon Lush?

Lemon Lush is a layered dessert, a citrus version if you will, of Chocolate Lasagna – Sex in a Pan. Traditionally, it’s made with buttery flour and pecan shortbread crust.

A sweet layer of cream cheese lays in between the shortbread and tangy lemon pudding.

A layer of whipped topping sits on top of the lemon pudding layer, completing the dessert.

While the traditional version of a lemon lush is delicious, it is definitely not low carb and loaded.

This low-carb keto lemon lush is sugar-free and allows you to enjoy all the bright flavors and luscious textures of the traditional version without all the carbs!

How to make low carb Keto Lemon Lush – helpful tips:

  • Make sure that the crust is completely set before you add the next layer, otherwise, it will melt and be generally icky.
  • If you want to lower the carbs a bit, you can make this crustless, but it will be more of a thick pudding.
  • This recipe can easily be doubled to feed more people.
  • Adding Xanthan Gum to the homemade whipped cream keeps it stable and prevents it from melting. If you don’t use the xanthan gum that’s fine, but I recommend waiting to make the whipped cream until just before serving.

Bottom crust layer:

Second layer:

Third lemon layer:

Top whipped cream layer:


  1. Preheat the oven to 350 degrees F and grease an 8×8 baking dish with non-stick spray.
  2. First, prepare the crust: In a large mixing bowl, combine butter and sugar substitute. Using an electric mixer beat until well-combined and fluffy. Add the vanilla and egg and mix again. Then add the almond flour and salt. Mix until everything is incorporated.
  3. Add chopped walnuts and transfer to the prepared baking dish and spread into an even layer. Bake for 10-15 minutes or just until the edges begin to brown.
  4. Set it aside to completely cool before assembling the dessert.
  5. While the crust is baking begin to prepare the lemon layer.
  6. In a medium mixing bowl, cream together the butter and sugar substitute with an electric mixer until light and fluffy.
  7. Add the eggs, one at a time while mixing at low speed, then add yolks. Continue to beat on low for another minute or two. The mixture should be smooth and creamy.
  8. Then add the lemon juice and continue to beat at low speed until incorporated. At this point, you are going to think that I have to lead you astray. The mixture will look lumpy and broken, but keep going.
  9. Transfer the mixture to a medium-sized saucepan and place over low heat. Whisk until the mixture is heated through and no longer has a curdled appearance.
  10. Increase the heat to medium and stir constantly, using a rubber spatula being sure to also scrape the bottom and sides of the saucepan, until the mixture thickened to a pudding-like texture.
  11. Remove from heat, sprinkle the Xanthan Gum on top, and whisk it into the lemon mixture.
  12. Transfer the mixture to a dish and place it in the fridge to cool before assembling the dessert.
  13. While the crust and the lemon layer are chilling, prepare the second layer: In a large mixing bowl, combine the Neufchatel cheese and the powdered sugar substitute. Beat with an electric mixer until well combined then add the Lemon extract and sour cream. Beat again until well combined, then add the heavy cream and continue mixing until the mixture is smooth and creamy.
  14. Next, prepare the whipped cream layer by combining the heavy cream, powdered sugar substitute, and vanilla in a large bowl. Beat with an electric mixer at high speed until the mixture has nearly doubled in size and formed soft peaks. Sprinkle with the xantham gum and continue beating until the mixture forms stiff peaks.
  15. To assemble the dessert, top the cooled crust with the second Neufchatel cheese layer, smoothing it into an even flat layer. Top the Neufchatel layer with the completely cooled lemon layer and smooth. Lastly, top with the whipped cream layer.
  16. Chill until ready to eat.

Lemon is my favorite year-round flavor. I live a keto/carnivore lifestyle. I am grateful that with the nutrition information for Lemon Lush you included total carbs. Net carbs may be considered when preparing vegetables but all other food items you must count total carbs! So many recipes I encounter display net carbs only. I am on a mission to correct this problem. I look forward to preparing Lemon Lush!

Made this today. Loved it and so did my husband. Got a little frustrated following recipe off phone going back and forth between ingredients and procedures. Send to email so I can print. Will copy and paste into my own format so directions follow each set of ingredients. Caused a little confusions for this long time baker. Great recipe though, no other problems.
