Ingredients
For the Keto Pie Crust

- 3 tablespoons melted butter
- 2 tablespoons powdered erythritol or monk fruit sweetener
- 1 teaspoon vanilla extract
- Pinch of salt
For the Lemon Filling
- 4 large egg yolks
- 1/2 cup powdered keto sweetener
- 1/2 cup fresh lemon juice
- 1 tablespoon lemon zest
- 1 cup heavy cream
- 4 ounces cream cheese, softened
- 1 teaspoon vanilla extract
Optional Topping

Instructions
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a mixing bowl, combine almond flour, melted butter, sweetener, vanilla extract, and salt. Stir until the mixture resembles wet sand.
Press the crust mixture firmly into a 9-inch pie pan, covering the bottom and sides evenly. Bake for 10 to 12 minutes or until lightly golden. Remove from the oven and let cool completely.
Step 2: Make the Lemon Filling
In a large bowl, beat the softened cream cheese until smooth. Add the egg yolks, sweetener, lemon juice, lemon zest, and vanilla extract. Mix until creamy and fully combined.
In a separate bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the lemon mixture to create a smooth and airy filling.
Step 3: Assemble the Pie
Pour the lemon filling into the cooled crust and spread evenly with a spatula. Refrigerate for at least 4 hours, or overnight for the best texture.
Step 4: Garnish and Serve
Before serving, top with sugar-free whipped cream, extra lemon zest, or lemon slices if desired. Slice and serve chilled.
Tips for the Best Keto Lemon Pie
- Use fresh lemon juice for the brightest flavor.
- Chill the pie overnight for cleaner slices.
- If you prefer a firmer texture, freeze the pie for 30 minutes before serving.
- Taste the filling before chilling and adjust sweetness if needed.
Storage Tips
Store the pie covered in the refrigerator for up to 5 days. You can also freeze individual slices for up to 2 months. Let thaw in the fridge before serving.
