  • ▢For the crust:
  • ▢2 cups almond flour
  • ▢½ cup chopped pecans
  • ▢⅓ cup powdered sugar free sweetener
  • ▢8 tablespoons melted butter
  • ▢For the filling:
  • ▢1 ⅓ cup cold heavy whipping cream
  • ▢8 ounces cream cheese softened at room temperature
  • ▢¾ cup powdered sugar free sweetener
  • ▢½ cup lemon juice
  • ▢sugar free whipped topping optional, if desired


  • Finely chop pecans. 
  • Chill a large mixing bowl (or the bowl of a stand mixer) in the freezer for at least 20 minutes before preparing filling (this helps keep the mixture cool).
  • Place chopped pecans and almond flour in a skillet. Heat over medium heat stirring frequently until golden brown. This takes about 10 minutes for the flour and nuts to be toasted and golden. 
  • Mix toasted flour, powdered Swerve, and melted butter in a medium size bowl. Stir until evenly mixed.
  • Press the mixture into the bottom and up the sides of a pie pan. Place in the refrigerator while you make the filling. 
  • Whip cream cheese with an electric mixer until smooth. 
  • Add in powdered Swerve and whip until smooth. Add in heavy cream and continue whipping on medium/high until light and fluffy and soft peaks form. 
  • Add in lemon juice and continue to whip on medium until well incorporated.
  • Spread in prepared crust. 
  • Cover and refrigerate for at least 4 hours before serving.


Slice into 8 pieces and serve with a dollop of sugar free whipped topping if desired. 

Keep any leftovers covered and refrigerated or freeze until ready to eat.
