How to Make Keto Lemon Lush

Making Keto Lemon Lush is not very difficult, but it does require some time and patience. You will need to make each layer separately and let them set in the fridge before adding the next layer. Here you will find all the steps that will help you to make this beautiful and delicious keto lemon dessert:

  1. Make the crust: In a bowl, mix almond flour, melted butter, erythritol (or sugar substitute of choice), and chopped walnuts. Press the mixture evenly into a 8×8 inch baking dish. Bake for 15 minutes at 180°C (350°F) or until golden brown. Let it cool completely.
  2. Make the cream cheese layer: In another bowl, beat cream cheese with an electric mixer until smooth. Add erythritol and vanilla extract and beat until well combined. Spread the mixture over the cooled crust.
  3. Make the lemon filling: In a small saucepan over low heat, whisk together lemon juice, water, erythritol, and gelatin until dissolved. Let it cool slightly. Pour the mixture over the cream cheese layer and refrigerate until set.
  4. Make the whipped cream layer: In a large bowl, whip heavy cream with an electric mixer until soft peaks form. Add erythritol and xanthan gum and whip until stiff peaks form. Spread the whipped cream over the lemon filling layer.
  5. Refrigerate and enjoy: Refrigerate the Keto Lemon Lush for at least an hour or overnight before serving. Cut into 16 pieces and enjoy!

Helpful Tips for Making Keto Lemon Lush

Here are some helpful tips to make this Keto Lemon Lush recipe even better:

  • Make sure that the crust is completely cooled before adding the cream cheese layer. Otherwise, the cream cheese will melt and mix with the crust.
Keto Lemon Lush Dessert step 1
  • You can use pecans instead of walnuts for the crust if you prefer.
Keto Lemon Lush Dessert step 2
  • You can use lemon zest to add more lemon flavor to the filling if you like.
Keto Lemon Lush Dessert step 3
  • You can use store-bought sugar-free whipped cream instead of making your own if you want to save time.
Keto Lemon Lush Dessert step 4
  • Adding Xanthan Gum to the homemade whipped cream keeps it stable and prevents it from melting. If you don’t have xanthan gum or don’t want to use it, you can skip it but make sure to serve the dessert soon after making it or keep it refrigerated until ready to serve.

You can make this dessert up to 5 days in advance and store it in an airtight container in the fridge.

Low Carb Keto Lemon Lush Dessert Recipe

Keto Lemon Lush: A Light and Fresh Low-Carb Dessert

Yield: 9
Prep Time: 30 minutes
Cook Time: 15 minutes
Total Time: 45 minutes

This low-carb Keto Lemon Lush is a light and fresh dessert that has a lemony filling between two creamy layers and a crunchy crust. It is a sugar-free and gluten-free version of the classic layered dessert that has a crunchy crust, a creamy cheese layer, and a tangy lemon filling. It is the ultimate keto lemon dessert that is perfect for any occasion.


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 mixingbowl, combine butter and sugar substitute. Using an electric mixer beat untilwell-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 cream cheese ( I use Philadelphia Neufchatel Cheese) and the powdered sugar substitute.
  14. 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.
  15. 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.
  16. 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.
  17. Chill until ready to eat.


This dessert needs to be set for about an hour or so before serving but you can make it up to 5 days in advance so it’s great for serving at parties and gatherings.

Made this last night and it is JUST what I was craving! I did not make the crust, but instead doubled the lemon filling and a little extra whipped cream layer, and cut back the sweetener a bit too. I just needed sour but creamy and this was perfect.

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.
