Preheat the oven to 350 F and take your pie crust out of the freezer.
First, add tofu, milk, and cornstarch into a blender, and blend on high until smooth.
Next, add the sugar and blend until smooth and fluffy.
Then, add vanilla, lemon juice, and vegan butter and blend until there are no chunks remaining.
Gently fold in coconut flakes until evenly dispersed and transfer mix into pie crust.
Bake for 60 minutes or until the top is lightly browned.
Let stand for 15 minutes and then put in the fridge to cool for 1 hour before enjoying!
Serve with vegan whipped cream or vanilla ice cream!
