Make the crust: Preheat the oven to 325˚ F. Coat a 9-inch pie pan with cooking spray. Whisk the egg white, granulated sugar, almond extract and salt in a medium bowl until frothy. Add the coconut and stir to combine. Press the mixture into the bottom and up the sides of the pie pan, then transfer to a baking sheet. Bake, rotating the pan occasionally, until the crust is golden brown around the edges and dry and lightly toasted in the center, 25 to 30 minutes. Transfer to a rack and let cool slightly.
Make the filling: Combine the butter and chocolate in a medium saucepan over medium-low heat. Cook, stirring, until melted and smooth, about 2 minutes. Remove from the heat and whisk in the brown sugar and granulated sugar until combined. Whisk in the eggs, almond extract and salt. Whisk in the almond flour until smooth.
Pour the filling into the crust. Loosely wrap a strip of foil around the crust edge to prevent it from over-browning. Bake on the baking sheet until a toothpick inserted into the center of the pie comes out mostly clean, about 30 minutes (the filling will crack slightly in spots). Transfer to the rack and let cool completely.
Make the topping: Whisk the heavy cream and confectioners' sugar in a medium bowl until soft peaks form. Spoon over the pie before serving.
