Preheat the oven to 325F
Combine almond flour, arrowroot flour and salt in a medium bowl. Add in the egg, maple syrup, butter and vanilla extract and stir until well-combined.
Form the dough into a ball and place it in the fridge to chill for 20 minutes.
Remove the dough from the fridge and place it on parchment paper. Rub a little butter between clean hands and form the dough into two flat crusts.
Slide the crusts (with the parchment paper still underneath) onto a baking sheet and bake for 14 minutes. Allow to cool before decorating with the whipped topping and fruit.
