01 - Preheat oven to 350°F. In a bowl, combine almond flour, powdered erythritol, melted butter, and salt until mixture resembles wet sand. Press firmly into the bottom and up the sides of a 9-inch pie dish, creating an even layer.
02 - Bake the crust for 8–10 minutes until lightly golden. Remove from oven and allow to cool completely before filling.
03 - Sprinkle gelatin powder over cold water in a small microwave-safe bowl. Let stand for 5 minutes to bloom. Microwave for 10–15 seconds until completely dissolved and liquid. Set aside to cool slightly.
04 - In a large bowl, beat softened cream cheese with powdered erythritol using an electric mixer until completely smooth and creamy, about 2 minutes.
05 - Pour in cold brew coffee and vanilla extract. Mix on medium speed until fully incorporated and the mixture is uniform in color.
06 - In a separate bowl, whip 1/2 cup heavy cream to stiff peaks. Gently fold the whipped cream into the cream cheese mixture until no white streaks remain.
07 - Stir the melted gelatin into the filling mixture, ensuring it is evenly distributed throughout.
08 - Pour the filling into the cooled crust, smoothing the top with an offset spatula. Refrigerate for at least 2 hours or until the filling is completely set and firm.
09 - Once the pie is set, whip the remaining 1/2 cup heavy cream with 1 tablespoon powdered erythritol until stiff peaks form.
10 - Spread or pipe the whipped cream over the chilled pie surface. Garnish with whole coffee beans or dust with cocoa powder if desired. Serve cold and keep refrigerated.
