Place coconut milk, coconut chips, 2 bananas, maple syrup and vanilla extract into a small saucepan.
Heat contents on medium heat, bananas will begin to soften and disintegrate.
At this point remove from heat and set aside.
Purée mango in blender or food processor, it should only take a few seconds, then set aside.
Pour heavy cream into a bowl and split vanilla bean and add the seeds to cream.
Whip cream until you arrive at a silky consistency - try not to whip the cream too firm, and then set aside.
Crush ginger snaps/cookies. I used my NutriBullet, just a quick pulse is necessary. Alternatively, place in a ziploc bag and crush with a rolling pin or bottle, by rolling over the ziploc bag, back and forth. Set aside once done.
Add the last sliced banana to the coconut milk mixture and stir until the recently added banana slices are coated with coconut milk.
To Serve
Spoon a generous amount of the banana and coconut mixture in the bottom of your sundae bowl, goblet or martini glass.
Layer with 2-3 spoonfuls of mango purée.
Add a layer of vanilla cream and then top generously with crushed ginger snaps.
Serve immediately.
