Instructions

  1. Step 1: In a medium bowl, combine 1 1/4 cups almond flour, 5 tbsp melted butter, and 3 tbsp erythritol sweetener, mixing until the mixture holds together like wet sand.
  2. Step 2: Press this crust mixture firmly into the bottom of a 7-inch springform pan, creating an even layer. Chill in the refrigerator for 15 minutes to set.
  3. Step 3: In a large bowl, beat together 8 oz softened cream cheese, 4 oz mascarpone cheese, 1 cup heavy cream, 1 1/2 tsp vanilla extract, and 2 tbsp powdered erythritol until smooth, thick, and fluffy, about 3-4 minutes.
  4. Step 4: Pour the cream cheese mixture over the chilled crust and smooth the top with a spatula.
  5. Step 5: Refrigerate the cheesecake for at least 4 hours or overnight until firm.
  6. Step 6: Before serving, top the cheesecake with 3/4 cup fresh blueberries, distributing them evenly across the surface.
