Ingredients Method Notes

Ingredients
  

For the crust
  • 1.5 cups almond flour Use finely ground for a tender crust; can swap for sunflower seed flour to keep it nut-free.
  • 0.25 cups unsweetened cocoa powder Choose natural cocoa for a bright note; Dutch-processed has a milder flavor.
  • 0.5 cups sugar substitute (erythritol or stevia) Erythritol mimics sugar’s texture best.
  • 0.5 cups unsalted butter, melted For a dairy-free version, use plant-based butter.
For the filling
  • 16 oz cream cheese, softened Use full-fat for smooth texture.
  • 1 cups sour cream Plain Greek yogurt can substitute but may yield a firmer set.
  • 0.5 cups lemon juice Freshly squeezed provides the best flavor.
  • 2 large eggs Bring to room temperature for even mixing.
  • 1 teaspoon vanilla extract Pure vanilla is recommended for depth of flavor.
  • 1 teaspoon lemon zest Avoid the white pith which is bitter.

Method
 

Preparation
  1. Preheat your oven to 325°F (163°C).
  2. In a mixing bowl, combine almond flour, cocoa powder, and sugar substitute.
  3. Pour in the melted butter and mix until well combined.
  4. Press the mixture into the bottom of a 9-inch springform pan to form a crust.
  5. Bake the crust for 10 minutes, then remove from the oven and let it cool.
Filling
  1. In another bowl, beat the cream cheese until smooth.
  2. Add the sour cream, lemon juice, eggs, vanilla extract, and lemon zest, mixing until fully combined.
  3. Pour the cheesecake filling over the cooled crust in the springform pan.
  4. Bake in the preheated oven for 50-60 minutes, or until the center is set but still slightly jiggly.
  5. Turn off the oven and let the cheesecake cool inside for 1 hour.
  6. Once cooled, refrigerate for at least 4 hours before serving.

Notes

Bring dairy and eggs to room temperature to avoid lumps; slow thaws prevent texture changes. Sift dry ingredients to prevent clumps and allow for an even crust.
