If you’re on a keto diet but craving something sweet, this Keto Key Lime Pie will hit the spot.
With its tangy lime flavor, creamy filling, and buttery almond crust, this dessert is a guilt-free indulgence perfect for satisfying your sweet tooth while staying within your carb limits.
In this article, we’ll dive into the details of making this delicious keto-friendly pie, with tips and tricks to ensure it turns out perfectly every time.
Why Keto Key Lime Pie?
Key lime pie is a classic dessert known for its zesty lime flavor and creamy texture.
However, traditional recipes often contain high amounts of sugar and carbs, making them unsuitable for those following a ketogenic diet.
This keto version retains all the key elements of the classic pie but substitutes high-carb ingredients with low-carb alternatives, ensuring you can enjoy a slice without derailing your diet.
Key lime pie Ingredients You’ll Need
Before you begin, gather the following ingredients. This recipe is divided into two parts: the crust and the filling.
For the Almond Flour Crust:
- 1 ½ cups almond flour: Almond flour is a perfect low-carb alternative to regular flour, offering a slightly nutty flavor that complements the lime filling.
- ¼ cup unsweetened shredded coconut: Adds a bit of texture and tropical flair to the crust.
- ¼ cup powdered erythritol: A keto-friendly sweetener that doesn’t raise blood sugar levels.
- ¼ cup melted butter: To bind the crust together and add richness.
- 1 teaspoon vanilla extract: For extra flavor depth.
For the Key Lime Filling:
- 1 cup heavy whipping cream: Provides the creamy texture necessary for the filling.
- ¾ cup powdered erythritol: Keeps the filling sweet without the carbs.
- 4 large egg yolks: Acts as a binder, giving the filling its firm but creamy consistency.
- ½ cup fresh key lime juice: The star of the pie, offering a tart and tangy flavor.
- 1 tablespoon key lime zest: Enhances the lime flavor and adds a touch of color.
- 1 teaspoon vanilla extract: Complements the lime and rounds out the flavor.
- ¼ teaspoon xanthan gum: A low-carb thickener that helps achieve the perfect pie consistency.
Step-by-Step Instructions
1. Prepare the Crust
Preheat your oven to 350°F (175°C). In a medium-sized bowl, combine the almond flour, shredded coconut, and powdered erythritol. Stir in the melted butter and vanilla extract until the mixture resembles wet sand.
Press the mixture evenly into the bottom of a 9-inch pie dish, ensuring it’s packed firmly to create a solid base. Bake the crust for 10-12 minutes or until it’s golden brown. Remove from the oven and let it cool while you prepare the filling.
2. Make the Key Lime Filling
In a large mixing bowl, beat the egg yolks until they are slightly thickened. Gradually add the powdered erythritol while continuing to beat until well combined. Slowly mix in the heavy whipping cream, key lime juice, zest, vanilla extract, and xanthan gum.
Once all the ingredients are well incorporated, pour the filling over the cooled almond flour crust. Smooth the top with a spatula to ensure an even layer.
3. Bake the Pie
Reduce the oven temperature to 325°F (163°C). Bake the pie for 15-20 minutes, or until the filling is set but still slightly jiggly in the center. The pie will continue to firm up as it cools.
4. Cool and Chill
Allow the pie to cool to room temperature before transferring it to the refrigerator. Let it chill for at least 3 hours, or overnight if possible, to allow the flavors to meld and the filling to fully set.
5. Serve and Enjoy
Once chilled, your Keto Key Lime Pie is ready to serve! You can garnish it with a dollop of whipped cream, a sprinkle of lime zest, or even a few thin lime slices for a decorative touch.
Tips for the Perfect Keto Key Lime Pie
- Use Fresh Key Limes: While bottled key lime juice can be convenient, fresh key limes provide the best flavor. They are more aromatic and have a distinctive taste that’s hard to replicate with bottled juice.
- Don’t Skip the Xanthan Gum: This ingredient is crucial for achieving the right texture in your filling. Without it, the filling may be too runny or not set properly.
- Chill Time is Essential: Resist the temptation to cut into your pie too soon. Chilling the pie allows the filling to set and the flavors to deepen, making for a much better-tasting dessert.
- Adjust Sweetness to Taste: Depending on your preference and the tartness of your limes, you may want to adjust the amount of sweetener. Taste the filling before baking and add more powdered erythritol if needed.

Keto Lime Pie Variations to Try
- Dairy-Free Version: Substitute the heavy whipping cream with coconut cream. This will slightly alter the flavor, adding a subtle coconut taste that pairs well with the lime.
- Chocolate Crust: For a twist, add 2 tablespoons of unsweetened cocoa powder to the crust ingredients. This will give your pie a chocolatey base that complements the tangy lime filling.
- Meringue Topping: For a more traditional Key Lime Pie look, add a layer of sugar-free meringue on top before the final bake. Whip egg whites with a keto-friendly sweetener until stiff peaks form, then spread over the filling before baking.
