Layered banana pudding with vanilla wafers, fresh bananas, and creamy custard is the quintessential Southern family dessert. This no-bake classic is a potluck legend that always gets scraped clean.
In a medium saucepan, combine sugar, cornstarch, and salt. Whisk in the eggs until fully blended.
Gradually whisk in the whole milk and place the pan over medium heat. Stir constantly, ensuring the custard thickens but does not boil, for 7–10 minutes.
Remove from heat, then stir in vanilla extract and heavy cream. Let the custard cool slightly, stirring occasionally to prevent a skin from forming.
Slice the bananas just before assembly to minimize browning.
In a 2-quart dish, layer vanilla wafers, banana slices, and a third of the custard. Repeat the layers twice, ending with custard. Cover and chill at least 2 hours before serving to allow the flavors to meld.
