03 - 1/4 cup unsalted butter, melted
04 - 1/2 teaspoon vanilla extract
05 - Pinch of salt

08 - 3/4 cup powdered erythritol
09 - 4 large egg yolks

→ Whipped Topping (optional)

13 - 1/2 cup heavy cream
14 - 1 tablespoon powdered erythritol
15 - 1/2 teaspoon vanilla extract

# How to Prepare:

01 - Preheat the oven to 350°F (175°C).
02 - In a medium mixing bowl, blend almond flour, powdered erythritol, melted butter, vanilla extract, and a pinch of salt until evenly incorporated. Firmly press the mixture into the base of a 9-inch pie dish, ensuring full coverage.
03 - Bake the crust for 10 to 12 minutes or until lightly golden. Remove from the oven and allow to cool slightly.
04 - In a separate bowl, vigorously whisk together key lime juice, lime zest, powdered erythritol, egg yolks, heavy cream, softened cream cheese, and vanilla extract until the mixture is smooth and homogeneous.
05 - Pour the prepared filling over the cooled crust, using a spatula to level the surface.
06 - Return the pie to the oven and bake for 10 to 12 minutes, until the center is just set and slightly jiggly. Remove and cool fully at room temperature.
07 - Refrigerate for at least 1 hour to ensure the filling firms before serving.
08 - Combine heavy cream, powdered erythritol, and vanilla extract in a mixing bowl. Beat with an electric mixer until stiff peaks form. Spoon or pipe atop the chilled pie if desired.
09 - Garnish with additional lime zest or thin slices of lime before presenting.
