12 ounces cream cheese softened

2 tablespoons Swerve Confectioners

Instructions

For the Crust:

Heat oven to 350 degrees F.

In mixing bowl combine almond flour, nuts and Sukrin Gold or Swerve Brown Sugar.

Cut in butter until a crumb mixture forms.

Put crumbs in 9-inch square baking and bake 12-15 minutes, stirring occasionally, until golden brown.

Reserving 1/4 cup crumbs, press remaining warm mixture into ungreased 9- or 10-inch pie pan, or 9-inch square pan. Chill.

For the Filling:

In medium saucepan, combine first three filling ingredients; blend in milk. Cook over medium heat, stirring constantly, until mixture boils and gelatin dissolves.

Slowly blend half the hot mixture into egg yolk, then return to saucepan and cook until mixture bubbles, stirring constantly. Remove from heat and transfer to mixing bowl.

Blend in cream cheese, lemon peel, lemon juice and vanilla. Beat until smooth and creamy.

Chill until mixture is thickened but not yet thick.

In small bowl, beat egg white until frothy. Gradually add 2 tablespoons Swerve Confectioners beating continuously until stiff peaks form.

In separate bowl, beat heavy whipping cream until stiff.

Fold beaten egg white into cooled cheese mixture. Next, fold in whipped cream.

Spoon filling into chilled pie/pan shell and sprinkle with reserve crumbs.

Chill 4 hours or overnight.
