Ingredients
  

  • Almond flour: Finely ground, blanched works best for the crust.
  • Unsalted butter: Melted, for binding the crust and adding flavor.
  • Granulated erythritol or allulose: Keto-friendly sweetener; allulose browns more easily and tastes very close to sugar.
  • Sea salt: A pinch to balance sweetness.
  • Cream cheese: Full-fat, brick style, softened.
  • Sour cream: Full-fat for a silky finish and gentle tang.
  • Heavy cream: Adds richness and helps that melt-in-your-mouth feel.
  • Eggs: Large, room temperature.
  • Pure vanilla extract: For warmth and aroma.
  • Lemon zest (optional): Brightens the flavor.
  • Ground cinnamon (optional): A pinch in the crust for warmth.
  • Fresh berries (optional): For serving.
  • Powdered erythritol or allulose (optional): For dusting or making a quick berry sauce.

Method
 

  1. Prep the pan and oven: Heat the oven to 325°F (163°C). Line the bottom of a 9-inch springform pan with parchment and lightly grease the sides. Wrap the outside of the pan with two layers of heavy-duty foil to prevent water from seeping in during the water bath.
  2. Make the crust: In a bowl, mix 1 1/2 cups almond flour, 3 tablespoons granulated erythritol or allulose, a pinch of sea salt, and a pinch of cinnamon (optional). Stir in 5 tablespoons melted butter until the mixture looks like damp sand.
  3. Press and par-bake: Press the crust firmly into the bottom of the pan in an even layer. Bake for 10 minutes, then set aside to cool slightly. Lower oven temperature to 300°F (150°C) for a gentler bake on the filling.
  4. Beat the cream cheese: In a large bowl, beat 24 ounces (680 g) softened cream cheese on medium-low until smooth, about 1–2 minutes. Avoid whipping in too much air.
  5. Add sweetener and flavor: Add 3/4 cup granulated erythritol or allulose and beat on low until combined. Mix in 1 tablespoon vanilla extract and 1 teaspoon lemon zest if using.
  6. Blend in dairy: Add 1/2 cup sour cream and 1/4 cup heavy cream. Beat on low just until smooth and creamy. Scrape the bowl as needed.
  7. Add eggs gently: Add 3 large eggs, one at a time, beating on low after each until just incorporated. Do not overmix; too much air causes cracks.
  8. Assemble the water bath: Pour the filling over the crust. Place the foil-wrapped pan in a large roasting pan. Pour hot water into the roasting pan until it comes halfway up the sides of the springform pan.
  9. Bake low and slow: Bake at 300°F (150°C) for 55–70 minutes. The edges should be set, and the center should still jiggle slightly like gelatin when you nudge the pan.
  10. Cool gradually: Turn off the oven, crack the door, and let the cheesecake rest inside for 45–60 minutes. This gentle cool-down helps prevent sinking and cracks.
  11. Chill completely: Remove the pan from the water bath, unwrap the foil, and run a thin knife around the edge. Cool on the counter until barely warm, then cover and refrigerate at least 6 hours, preferably overnight.
  12. Slice and serve: Release the springform ring. Warm a sharp knife under hot water, dry it, then slice for clean edges. Serve plain, with a few berries, or with a quick berry sauce.
