This banana pudding has the same basic structure as Magnolia Bakery’s, without the instant pudding mix or sweetened condensed milk. It's got pudding, bananas, Nilla wafers, and whipped cream, but instead of vanilla pudding from a box I’ve whisked up a deeply flavorful butterscotch pudding. No need to try to bake your own cookies, though; there is no adequate substitute for Nilla wafers.
