In a mixing bowl or food processor, add the almond meal, tapioca flour, brown monk fruit sweetener and ghee or butter.
Mix with an electric mixer, food processor or pastry blender until coarse crumbs form.
Add the vanilla extract, salt and egg, then mix until a soft dough forms
Cover the bowl and place the dough in the refrigerator to chill for at least 30 minutes, or up to overnight.
Prepare the Pan and Blind Bake the Crust:
Preheat your oven to 160°C fan or 180°C conventional (about 320–350°F).
Line a 20 cm (8 inch) square baking pan with parchment paper, covering the bottom and sides.
Press the chilled crust dough evenly into the base of the pan, making sure it reaches all corners.
Use a fork to gently prick the dough all over. This helps prevent the crust from puffing up.
Bake the crust in the preheated oven for about 15 minutes, until the edges are just turning light golden.
Remove from the oven and set aside while you prepare the filling
