Preheat your oven to 350°F (175°C).
Mix the graham cracker crumbs with the melted vegan butter in a bowl. Mix until the texture resembles wet sand.
Carefully press the mixture into the bottom and along the sides of a 9-inch pie dish.
Bake for 8-10 minutes, then allow the crust to cool down completely.
In a blender, blend together the chilled coconut cream, plant-based milk, maple syrup, vanilla extract, and cornstarch. Blend until smooth.
Pour the mixture into a saucepan and cook on medium heat, stirring constantly until it thickens (this should take around 5-7 minutes).
Take it off the heat and gently mix in the sliced bananas.
Gently pour the banana cream filling into the cooled crust. Use a spatula to spread it evenly.
Gently spread the filling to smooth the top, then cover the pie with plastic wrap. Place the pie in the fridge for at least 6 hours, or overnight, to let it set.
Just before serving, add extra banana slices and a dollop of vegan whipped cream. For extra flair, sprinkle crushed nuts or vegan chocolate shavings on top.
Slice and enjoy!
