Ingredients
  

  • For the crust: 1 1/2 cups almond flour
  • 1/4 cup granulated erythritol or allulose (or your preferred keto sweetener)
  • 1/4 teaspoon fine sea salt
  • 5 tablespoons unsalted butter, melted
  • 1/2 teaspoon vanilla extract
  • For the filling: 24 ounces (3 blocks) full-fat cream cheese, softened to room temperature
  • 2/3–3/4 cup powdered erythritol or allulose
  • 3 large eggs, at room temperature
  • 1/2 cup sour cream, at room temperature
  • 2 teaspoons vanilla extract
  • 1 tablespoon lemon juice (fresh) and 1/2 teaspoon lemon zest
  • Pinch of salt
  • Optional toppings: Fresh berries (raspberries, strawberries, blueberries)
  • Shaved dark chocolate (90% cacao or sugar-free)
  • Whipped cream (unsweetened or lightly sweetened with keto sweetener)

Method
 

  1. Prep the pan and oven. Preheat your oven to 325°F (163°C). Line the bottom of a 9-inch springform pan with parchment and lightly grease the sides. Wrap the exterior of the pan with a layer of heavy-duty foil if you plan to use a water bath.
  2. Make the crust. In a bowl, mix almond flour, erythritol, salt, melted butter, and vanilla until the texture resembles damp sand. Press firmly into the bottom of the pan in an even layer. Use the bottom of a glass to compact it well.
  3. Par-bake the crust. Bake for 10–12 minutes until lightly golden and fragrant. Remove and let it cool while you prepare the filling. Reduce oven temperature to 300°F (150°C) for a gentler bake.
  4. Beat the cream cheese. In a large bowl, beat softened cream cheese with a handheld mixer on medium speed until smooth and lump-free, about 1–2 minutes. Do not overbeat.
  5. Add sweetener and flavorings. Beat in powdered sweetener, vanilla, lemon juice, zest, and a pinch of salt. Mix just until combined and silky.
  6. Incorporate sour cream. Add sour cream and mix on low speed until fully blended. Scrape the bowl and paddle to catch any streaks.
  7. Add the eggs. Add eggs one at a time on low speed, mixing just until incorporated after each addition. Avoid whipping air into the batter to prevent cracks.
  8. Pour and smooth. Pour the filling over the cooled crust. Tap the pan on the counter a few times to release air bubbles. For a water bath, place the springform inside a larger pan and pour hot water around it to reach halfway up the sides.
  9. Bake low and slow. Bake at 300°F (150°C) for 55–70 minutes. The edges should be set, and the center should jiggle slightly like gelatin. Do not overbake.
  10. Cool gradually. Turn off the oven, crack the door, and let the cheesecake rest for 1 hour. This gentle cooling reduces cracking.
  11. Chill fully. Remove the pan, run a thin knife around the edge, and cool at room temperature another 30 minutes. Then cover and refrigerate for at least 6 hours, preferably overnight.
  12. Slice and serve. Release the springform, slice with a hot, clean knife, and serve plain or with berries, chocolate shavings, or a dollop of whipped cream.
