Step 1

Preheat the oven to 350F. In a large bowl, whisk together almond flour, sweetener, and salt. Stir in the melted butter until well combined.

Step 2

Press evenly into the bottom of an 8-inch square pan and bake 10 minutes - it won't be cooked through. Set aside and let cool.

Step 3

Reduce the oven temperature to 275F.

Step 4

Beat the cream cheese in a large bowl until smooth. Beat in the sweetener, and then beat in the lemon zest, lemon juice, and cream until no lumps remain.

Step 5

Beat in the eggs until just combined - do not overbeat as this can cause cracking.

Step 6

Spread the filling over cooled crust and bake 35 to 45 minutes, or until filling is just set and the center barely jiggles when shaken.

Step 7

Let cool 30 minutes, then chill for at least 2 hours.

Step 8

Garnish with powdered sweetener and additional lemon zest, if desired.
