01 - Preheat oven to 350°F. Combine almond flour, powdered erythritol, melted butter, and salt in a bowl until mixture resembles wet sand.
02 - Press mixture firmly into the bottom and up the sides of a 9-inch pie dish. Bake for 8-10 minutes until lightly golden. Allow to 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 completely dissolved and liquid.
04 - Beat softened cream cheese with powdered erythritol in a large bowl until completely smooth and no lumps remain.
05 - Pour in cold brew coffee and vanilla extract. Mix until fully incorporated and uniform in color.
06 - Whip 1/2 cup heavy cream to stiff peaks. Gently fold whipped cream into the cream cheese mixture until no white streaks remain.
07 - Stir the melted gelatin into the filling mixture until completely blended. Work quickly as gelatin will begin to set.
08 - Pour filling into the cooled crust. Smooth the top with an offset spatula. Refrigerate for at least 2 hours or until completely set.
09 - Whip remaining 1/2 cup heavy cream with 1 tbsp powdered erythritol to stiff peaks.
10 - Spread or pipe whipped cream over the chilled pie surface. Garnish with whole coffee beans or dust with cocoa powder if desired. Serve cold.
