Mix the cornstarch, sugar, and salt in a medium sized saucepan. Add ½ cup of the milk and whisk to make a smooth paste. Whisk in the remaining milk and entire can of coconut milk.
“Cook” on medium high, whisking constantly, until the mixture thickens and begins to bubble. (You want it to be super thick)
Turn down heat and simmer for one minute. Remove from the heat and stir in vanilla extract. In a medium glass bowl, layer crackers, banana slices and then pudding, in that order.
Cover the pudding with plastic wrap and chill for 2 hours, or overnight.
