Ingredients
  

  • Almond crust
  • Almond flour 1 ½ cups
  • Unsalted butter melted 6 tablespoons
  • Granulated erythritol or keto sweetener 3 tablespoons
  • Vanilla extract 1 teaspoon
  • Salt a pinch
  • Cheesecake layer
  • Cream cheese softened 16 ounces
  • Powdered erythritol ½ cup
  • Eggs room temperature 2 large
  • Heavy cream ¼ cup
  • Vanilla extract 1 ½ teaspoons
  • Lemon zest ½ teaspoon
  • Blackberry swirl
  • Fresh or frozen blackberries 1 cup
  • Powdered erythritol 2 tablespoons
  • Water 1 tablespoon
  • Lemon juice 1 teaspoon

Instructions
 

  • Preheat oven to 325°F (165°C) and line an 8×8-inch pan with parchment.
  • Mix almond flour, melted butter, erythritol, vanilla, and salt until it resembles wet sand; press evenly into the pan and bake 10 minutes. Cool lightly.
  • Simmer blackberries, powdered erythritol, water, and lemon juice 4–6 minutes until pourable, mash gently, and strain if you want a seedless sauce. Cool fully.
  • Beat softened cream cheese with powdered sweetener until smooth, add eggs one at a time, then stir in heavy cream, vanilla, and lemon zest. Pour over crust.
  • Drop spoonfuls of blackberry sauce over the filling and lightly swirl with a toothpick or knife.
  • Bake 25–30 minutes until edges are set and the center still jiggles softly. Cool at room temperature, then refrigerate 2–3 hours. Slice into 12 bars.

Notes

Use room-temperature cream cheese for a silky filling.
Avoid over-swirling so the purple marbling stays bold.
Let bars chill fully—this controls moisture and gives clean slices.
