Prepare the Crust – In a bowl, combine almond flour, melted butter, powdered erythritol, and grated lemon zest. Mix well and press the mixture into the bottom of a lined springform pan. Refrigerate while preparing the filling.
Dissolve the Gelatin – In a small bowl, mix the fresh lemon juice with unflavored gelatin and let it sit for a few minutes until it thickens.
Make the Filling – Beat the room-temperature cream cheese with a low-carb sweetener until smooth. Gradually add the whipping cream, vanilla extract, and fresh lemon zest, mixing until creamy.
Incorporate the Gelatin – Warm the gelatin mixture slightly to dissolve it completely, then slowly pour it into the cheesecake filling while stirring continuously.
Chill to Set – Pour the filling over the prepared crust and smooth the top. Refrigerate for at least 4-6 hours or overnight for the best texture.
Serve and Enjoy – Once set, remove from the pan, slice, and garnish with extra lemon zest if desired. Serve chilled and enjoy!
