Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the almond flour, coconut flour, erythritol, salt, and unsweetened shredded coconut for the crust.
Add the melted butter to the dry mixture and stir until everything is well combined and resembles coarse crumbs.
Press the crust mixture firmly into the bottom of a small baking dish or ramekin, creating an even layer.
Bake the crust in the preheated oven for about 12 minutes, or until it's golden brown. Once baked, remove from the oven and let it cool completely.
In another mixing bowl, whisk together the coconut cream, erythritol, coconut extract (if using), and vanilla extract until smooth and well combined.
Pour the coconut cream mixture over the cooled crust, spreading it evenly.
Place the dish in the refrigerator and let it chill for at least 1-2 hours, allowing the coconut cream filling to set.
Once chilled, remove the coconut cream pie bar from the refrigerator.
Top the pie bar with a dollop of unsweetened whipped cream and a sprinkle of toasted coconut flakes.
