In a saucepan, combine coconut milk, brewed coffee, maple syrup, and salt. Stir well until smooth.
In a small bowl, whisk cornstarch with a little cold water to form a slurry.
Slowly add the cornstarch mixture into the saucepan while whisking constantly.
Bring to a simmer over medium heat and cook until thickened, about 5–7 minutes.
Remove from heat and stir in vanilla extract.
Let the filling cool slightly before pouring it into the pre-baked pie crust.
Refrigerate for at least 2 hours to set the filling.
Once set, top with vegan whipped cream and a dusting of cocoa or chocolate shavings for extra flair.
Serve chilled and watch people think you’ve mastered the art of “fancy” baking.
