A Refreshing Low-Carb Dessert with a Creamy, Tangy Lemon Filling, Homemade Keto Graham Cracker Crust, and Fluffy Whipped Cream Topping
There's something wonderfully refreshing about a homemade lemon cream pie.
That delicious combination of tangy lemon filling, a buttery graham cracker crust, and a generous layer of fluffy whipped cream makes it a dessert that's hard to resist.
And who says you can't enjoy a delicious lemon cream pie while eating keto?
Not in my kitchen!
Let's get creative and make a Keto Mock Lemon Cream Pie using my homemade Keto Mock Graham Cracker Crust.
Instead of relying on sweetened condensed milk, sugar, and a traditional graham cracker crust, we're making a creamy lemon filling with cream cheese, heavy whipping cream, fresh lemon juice, and a keto-friendly sweetener.
And to help our filling hold its shape when sliced, we're using a little unflavored gelatin.
The result is a cool, creamy dessert with a bright lemon flavor and a delicious homemade crust.
Best of all, this pie can be prepared ahead of time and refrigerated until you're ready to serve it.
What Makes This a Mock Lemon Cream Pie?
Traditional lemon cream pies come in several varieties.
Some are prepared with sweetened condensed milk, while others use cooked lemon custard, cream cheese, or whipped cream.
The keto version takes a slightly different approach.
Use a combination of cream cheese and heavy whipping cream to create a rich, smooth filling.
Fresh lemon juice and lemon zest provide that wonderful citrus flavor.
A powdered keto-friendly sweetener replaces traditional sugar.
And my homemade Keto Mock Graham Cracker Crust gives the pie a buttery, slightly cinnamon-flavored foundation.
Use unflavored gelatin to help the filling set properly.
The finished dessert is creamy, refreshing, and easy to slice once it has been thoroughly chilled.
Keto Mock Lemon Cream Pie Recipe
Servings: 8 slices
Preparation Time: Approximately 25 minutes, plus crust preparation
Chilling Time: 4–6 hours, preferably overnight
Total Time: Approximately 5–7 hours, including chilling
Ingredients for the Crust
- 1 prepared 9-inch Keto Mock Graham Cracker Crust, completely cooled
Use my previously published **Keto Mock Graham Cracker Crust** recipe, made with almond flour, coconut flour, cinnamon, keto-friendly sweetener, butter, and vanilla.
Prepare the crust according to that recipe before beginning the filling.
Ingredients for the Lemon Cream Filling
- 8 ounces full-fat cream cheese, softened
- 1 cup heavy whipping cream, cold
- ½ cup powdered keto-friendly sweetener, or to taste
- ⅓ cup freshly squeezed lemon juice
- 1 tablespoon finely grated lemon zest
- 1 teaspoon vanilla extract
- 1 teaspoon unflavored gelatin
- 2 tablespoons cold water
- A small pinch of salt
Ingredients for the Whipped Cream Topping
- ¾ cup cold heavy whipping cream
- 1–2 tablespoons powdered keto-friendly sweetener
- ½ teaspoon vanilla extract
- Additional lemon zest for garnish
- Thin lemon slices or twists for decoration, optional
Step 1: Prepare the Keto Mock Graham Cracker Crust
Begin by preparing your homemade Keto Mock Graham Cracker Crust.
Press the crust mixture firmly into the bottom and up the sides of a 9-inch pie plate.
Follow the baking or chilling directions in the original crust recipe.
Allow the crust to cool completely before adding the lemon filling.
This is important because a warm crust can soften the cream filling before it has a chance to set.
I prefer preparing the crust ahead of time.
That way, when I'm ready to make the filling, everything is waiting for me.
And if you haven't tried my Keto Mock Graham Cracker Crust yet, this lemon cream pie is a wonderful reason to make it!
Step 2: Prepare the Gelatin
Place 2 tablespoons of cold water into a small heatproof bowl.
Sprinkle the unflavored gelatin evenly over the water.
Allow it to stand for approximately 5 minutes.
This process is called blooming.
The gelatin absorbs the water and becomes soft.
Next, gently warm the bloomed gelatin until it dissolves completely.
You can do this by placing the bowl over a larger bowl of hot water and stirring.
Do not boil the gelatin.
Once dissolved, allow it to cool until lukewarm, but don't let it begin setting.
We'll add it to the lemon filling shortly.
Step 3: Beat the Cream Cheese
Place the softened cream cheese into a large mixing bowl.
Using an electric mixer, beat until smooth and creamy.
Add the powdered keto-friendly sweetener and continue mixing until well combined.
I recommend using a powdered sweetener rather than a granulated one.
Why?
Because powdered sweetener blends more smoothly into cold cream fillings.
Granulated sweeteners can sometimes leave a slightly gritty texture.
And you certainly don't want that in your beautiful lemon cream pie!
Taste the mixture and adjust the sweetness if necessary.
Different keto sweeteners have different sweetness levels, so use the amount that works best with your chosen product.
Step 4: Add the Fresh Lemon Flavor
Add the freshly squeezed lemon juice, finely grated lemon zest, vanilla extract, and pinch of salt to the cream cheese mixture.
Beat until smooth.
Now we're getting somewhere!
The fresh lemon juice adds that wonderful tangy flavor, while the zest brings out the natural lemon aroma.
I especially like using fresh lemons in this recipe.
Bottled lemon juice can work in a pinch, but fresh lemon juice and zest give the filling a brighter flavor.
When grating the zest, remove only the yellow outer layer of the lemon peel.
Avoid the white pith underneath because it can taste bitter.
Step 5: Add the Gelatin
Before adding the gelatin, make sure it is completely dissolved and still fluid.
Take approximately 2 tablespoons of the lemon cream cheese mixture and stir it into the lukewarm gelatin.
This helps bring the two mixtures closer in temperature.
Then slowly pour the gelatin mixture into the remaining lemon filling while beating on low speed.
Continue mixing until everything is thoroughly combined.
This step helps prevent little pieces of gelatin from forming in the filling.
You want a smooth, creamy pie that holds together beautifully when sliced.
Step 6: Whip the Heavy Cream
In a separate chilled mixing bowl, pour 1 cup of cold heavy whipping cream.
Beat with an electric mixer until medium peaks form.
The cream should be fluffy and thick enough to hold its shape, but not dry or grainy.
Now gently fold the whipped cream into the lemon cream cheese mixture.
Use a spatula and work carefully.
Try to keep as much of that lovely airiness as possible.
Continue folding until the mixture is smooth and evenly blended.
The filling should be thick, creamy, and light.
Step 7: Fill the Pie Crust
Spoon the lemon cream filling into the prepared Keto Mock Graham Cracker Crust.
Use a spatula to spread the filling evenly.
Smooth the top or create gentle decorative swirls.
I like a slightly swirled finish because it gives a homemade pie a beautiful appearance without requiring anything fancy.
Cover the pie carefully and place it in the refrigerator.
Chill for at least 4–6 hours, preferably overnight.
The chilling time allows the gelatin to set and the filling to become firm enough to slice.
Don't rush this step.
A well-chilled cream pie is much easier to serve.
Step 8: Prepare the Whipped Cream Topping
Once the lemon filling has set, prepare the whipped cream topping.
Pour ¾ cup of cold heavy whipping cream into a chilled bowl.
Add the powdered keto-friendly sweetener and vanilla extract.
Beat until firm peaks form.
The whipped cream should hold its shape when lifted with the beaters.
Be careful not to overbeat it.
You can spread the whipped cream over the entire pie or pipe decorative swirls around the edges.
Either way, it makes a beautiful finishing touch.
Step 9: Garnish and Serve
Sprinkle a little freshly grated lemon zest over the whipped cream.
If desired, decorate the pie with a few thin lemon slices or lemon twists.
The bright yellow lemon zest looks especially pretty against the white whipped cream.
Keep the pie refrigerated until you're ready to serve.
For the neatest slices, use a sharp knife dipped in warm water and wiped dry between cuts.
And there you have it!

Why Use Gelatin in a Lemon Cream Pie?
Because we're not using traditional sweetened condensed milk or a cooked custard filling, we need something to help our cream cheese and whipped cream mixture hold together.
That's where unflavored gelatin comes in.
A small amount helps stabilize the filling without turning it into a firm gelatin dessert.
We want our pie to remain creamy.
The gelatin simply gives it enough structure to hold a slice.
And remember, the pie must be thoroughly chilled before cutting.
Can You Make This Pie Without Gelatin?
Yes, although the filling will be softer.
If you prefer not to use gelatin, you can prepare the filling without it.
However, the pie may need to be served as a soft cream dessert rather than a firm, neatly sliced pie.
For a more reliable sliceable filling, I recommend keeping the gelatin in the recipe.
Can You Use Bottled Lemon Juice?
Yes, but I prefer fresh lemons because bottled lemon juice has preservatives. Fresh is always best if you can.
Fresh lemon juice has a bright flavor that works beautifully in cream desserts.
And because you're using lemon zest, you'll need fresh lemons anyway.
Depending on their size and juiciness, approximately 2–3 lemons should provide enough juice for this recipe.
If you enjoy a stronger lemon flavor, add a little extra zest rather than significantly increasing the lemon juice.
Too much additional liquid can affect the filling's consistency.
More Ways to Customize Your Lemon Cream Pie
Here's where you can have a little fun!
Extra Tangy Lemon Cream Pie: Add another teaspoon of finely grated lemon zest.
Lemon Vanilla Cream Pie: Increase the vanilla slightly for a softer, sweeter flavor.
Lemon Coconut Cream Pie: Add a small amount of unsweetened finely shredded coconut to the filling or sprinkle it over the topping.
Lemon Berry Cream Pie: Garnish each serving with a few fresh raspberries or blueberries.
Individual Lemon Cream Desserts: Divide the crust mixture and filling among small dessert cups instead of making one large pie.
Lemon Cheesecake Cream Pie: Increase the cream cheese slightly for a denser, cheesecake-style filling, adjusting the texture as needed.
One of the things I enjoy about homemade desserts is how easily you can experiment with flavors.
A little extra lemon zest, a different garnish, or a change in presentation can make a familiar recipe feel entirely new.
Can You Make Keto Mock Lemon Cream Pie Ahead of Time?
Yes!
In fact, I think this is one of those desserts that benefits from being prepared the day before serving.
The extra chilling time allows the filling to become fully set.
It also gives the lemon flavor time to blend with the cream cheese and whipped cream.
Prepare the pie the day before, cover it carefully, and refrigerate.
For the freshest appearance, add the whipped cream topping shortly before serving.
That way, the topping remains fluffy and attractive.
How to Store Leftover Lemon Cream Pie
Because this pie contains cream cheese and heavy whipping cream, it must be refrigerated.
Cover the pie or transfer individual slices to airtight containers.
Store in the refrigerator for approximately 3–4 days.
Do not leave the pie sitting at room temperature for extended periods.
For best quality, serve it chilled.
Can You Freeze Keto Mock Lemon Cream Pie?
Yes, although the texture may change slightly after thawing.
Cream-based fillings sometimes release moisture or become a little grainy after freezing.
If you want to freeze the pie, I recommend doing so before adding the whipped cream topping.
Wrap the chilled, fully set pie carefully and freeze for approximately 1–2 months for best quality.
Thaw overnight in the refrigerator.
Add freshly whipped cream before serving.

Why Homemade Keto Desserts Are Worth Making
One of the nicest things about preparing desserts at home is having control over the ingredients.
You can adjust the sweetness, choose your favorite keto-friendly sweetener, and decide how much lemon flavor you want.
You can also prepare the crust ahead of time and make the filling when it's convenient.
And you don't need an elaborate collection of ingredients or fancy decorating equipment.
A mixing bowl, electric mixer, pie plate, and a little patience are all you really need.
That's my kind of homemade dessert!
