Preheat oven to 180celsius. Grease a tart pan. Set aside.
In a bowl, combine quinoa flakes, oat flour, almond meal, coconut oil, and maple syrup. You should get a moist mixture than can be easily moulded. Firmly press into bottom and up the sides of tart tin. Bake for 12-15 mins until crust is golden brown. Transfer to a wire rack and let it cool.
