01 - Preheat oven to 350°F. In a bowl, combine almond flour, powdered erythritol, melted butter, and salt. Mix until well combined and press firmly into the bottom and up the sides of a 9-inch pie dish.
02 - Bake the crust for 8-10 minutes until lightly golden. Remove from oven and let cool completely before filling.
03 - Sprinkle gelatin powder over cold water in a small bowl. Let stand for 5 minutes to bloom. Microwave for 10-15 seconds until melted and liquid.
04 - Beat softened cream cheese with powdered erythritol in a large bowl until smooth and creamy. Add cold brew coffee and vanilla extract, mixing until fully incorporated.
05 - Whip 1/2 cup heavy cream to stiff peaks. Gently fold whipped cream into the cream cheese mixture until no white streaks remain.
06 - Stir melted gelatin into the filling until fully incorporated. Pour filling into the cooled crust and smooth the top with an offset spatula.
07 - Refrigerate for at least 2 hours until the filling is completely set and firm to the touch.
08 - Whip remaining 1/2 cup heavy cream with 1 tbsp powdered erythritol to stiff peaks. Spread or pipe over the chilled pie surface.
09 - Garnish with whole coffee beans or dust with cocoa powder if desired. Serve chilled and store refrigerated.
