Preheat your oven to 350°F (175°C).
In a mixing bowl, simply combine the almond flour, coconut flour, sweetener, and a pinch of salt.
Add in the softened butter and mix well until a consistent dough forms.
Press this dough evenly into the bottom and up the sides of a greased 9-inch pie pan.
Bake for 12 to 15 minutes, or until it turns lightly golden. Allow it to cool completely before you add the delicious filling.
In a dry skillet over medium heat, gently roast the shredded coconut until it's golden and smells wonderful. Set it aside to cool.
Using a food processor, blend the soaked pistachios until they become a thick, creamy paste.
Now, add the matcha powder, coconut milk, sweetener, coconut oil, and salt. Continue to blend until the mixture is beautifully smooth.
Gently fold in the roasted coconut flakes. This adds a lovely texture to your filling.
Spread this flavorful pistachio mixture evenly into your cooled pie crust.
In a small saucepan, gently heat the coconut milk until it just begins to simmer.
Pour the warm coconut milk over the chopped chocolate in a heatproof bowl. Let it sit for about 1 minute to melt, then stir until it's perfectly smooth and glossy.
Allow the ganache to cool slightly, then carefully pour it over the pistachio filling, smoothing it out with a spatula.
