Preheat the oven to 325ºF and lightly grease a glass or ceramic pie pan. Prepare the crust according to the directions.
Press the crust into the bottom and sides of the prepared pan, coming only ¾ of the way up the sides. Crimp the edges decoratively and prick the bottom with a fork.
Bake 10 minutes, then remove and let cool completely.
Brownie Filling
In a medium bowl, whisk together the almond flour, allulose, Swerve, cocoa powder, collagen, baking powder, and salt.
Stir in the butter, eggs, egg yolk, coffee, and vanilla extract until well combined. Spread the batter in the cooled crust.
Sprinkle the top with chocolate chips and bake 20 to 25 minutes, until set around the edges but still a little wet looking in the center. Remove and let cool completely.
