Step-by-Step Preparation

Step 1: Prepare the Crust

  1. Preheat oven to 175°C (350°F).

  2. Mix almond flour, melted butter, sweetener, vanilla, and salt until crumbly but cohesive.

Step 2: Prepare the Filling

  1. Beat cream cheese with sweetener until smooth.

  2. Add eggs one at a time, mixing gently.

  3. Stir in lemon juice, zest, heavy cream, and vanilla until creamy and uniform.

Step 3: Assemble and Bake

  1. Pour cheesecake filling over the baked almond crust, smoothing the top.

Step 4: Chill
