Combine plant milk and condensed coconut milk in a sauce pan and whisk in corn starch until the mixture is relatively smooth.
Whisk in pureed banana (baby food).
Bring the entire mixture to boil over medium heat. Once boiling, turn the heat down to low and cook for a couple of minutes. The mixture will thicken.
Whisk in vanilla extract.
Set aside.
Line the bottom of your casseroled dish with a single layer of Biscoff cookies.

Repeat the layering using the remaining pudding and bananas.
Spread whipped topping evenly over the top layer of bananas.
Finely crumble 3 or 4 Biscoff cookies and sprinkle on top.
