Preheat oven to 325ºF and grease a 9-inch square pan well.
In a medium bowl, whisk together the almond flour, sweetener, baking powder, and salt.
Add the egg, melted butter, and vanilla extract and beat until the dough comes together. Stir in the chocolate chips.
Press about two-thirds of the dough into the bottom of the prepared pan. Bake 12 to 15 minutes, until light golden brown, then remove from the oven and let cool (it will not be fully baked at this point).
Filling
In a large bowl, beat the cream cheese until completely smooth, about 1 minutes. Add the powdered sweetener, sour cream, and vanilla and beat until smooth. Finally beat in the egg until just combined.
Pour the filling over the cooled crust. Take the remaining cookie crust mixture and crumble over the top of the filling, pressing lightly to adhere.
Bake 20 to 25 minutes or until the top crust is golden and the filling is just a little jiggly in the center. Remove from the oven and let cool, then refrigerate for 1 hour until set.
