Ingredients
  

  • For the crust: 1 1/2 cups almond flour (super-fine)
  • 3 tablespoons granulated erythritol or allulose
  • 1/4 teaspoon fine sea salt
  • 5 tablespoons unsalted butter, melted
  • 1/2 teaspoon vanilla extract
  • For the filling: 12 ounces cream cheese, softened
  • 1/2 cup powdered erythritol or allulose
  • 2 large eggs, room temperature
  • 1/3 cup full-fat sour cream
  • 1 teaspoon lemon zest
  • 1 teaspoon vanilla extract
  • 1 cup fresh blueberries (or 3/4 cup frozen, unthawed)
  • Optional finishing: 1 tablespoon lemon juice
  • Additional blueberries for topping
  • A few mint leaves for garnish
  • Equipment: 8-inch square pan or 9-inch springform pan
  • Mixing bowls and hand mixer
  • Parchment paper

Method
 

  1. Prep the pan: Line your pan with parchment, leaving overhang for easy lifting. Preheat oven to 325°F (163°C).
  2. Make the crust: In a bowl, combine almond flour, granulated sweetener, and salt. Stir in melted butter and vanilla until the texture feels like damp sand.
  3. Press and bake: Press the crust firmly and evenly into the pan. Bake 8–10 minutes, until lightly set and just starting to color. Let cool 5 minutes.
  4. Beat the filling: In another bowl, beat cream cheese and powdered sweetener until smooth and fluffy, about 1–2 minutes.
  5. Add the wet ingredients: Beat in eggs one at a time until just combined. Mix in sour cream, lemon zest, and vanilla. Do not overmix.
  6. Fold in berries: Gently fold in blueberries. If using frozen, add straight from the freezer to avoid bleeding.
  7. Pour and smooth: Spread the filling over the crust, smoothing the top. Tap the pan gently to release air bubbles.
  8. Bake: Bake 25–30 minutes, until edges are set and the center still has a slight jiggle. It will firm up as it cools.
  9. Cool and chill: Cool to room temperature, then refrigerate at least 3 hours, preferably overnight, for clean slices.
  10. Finish: Before serving, drizzle with a touch of lemon juice, add a few extra blueberries, and garnish with mint if you like.
