Step 1In a large bowl, combine milk, vanilla pudding mix and sweetened condensed milk. Whisk thoroughly, breaking up any lumps, and refrigerate for at least 5 minutes, or until set.
Step 2In another large bowl, combine heavy cream, powdered sugar and vanilla. Beat until stiff peaks form, 2 to 3 minutes. Set aside 1/3 of the mixture for topping the dish. Fold remaining whipped cream into the pudding mixture.
Step 3Build the trifle: Spread one-third of the pudding mixture onto the bottom of the trifle dish. Cover with a layer of nutter butter cookies—you may want to also stand some cookies up vertically, so you see the full circle along the edge of the trifle dish. Top with an even layer of banana slices then drizzle melted peanut butter on top. Continue layering the pudding, nutter butters, banana slices, and peanut butter until you reach the top, ending with a final layer of pudding.
Step 4Refrigerate for at least 3 hours, or up to overnight.
Step 5Just before serving, dollop whipped cream on top of the pudding layer, then sprinkle crumbled Nutter Butters on top and drizzle with melted peanut butter.
