Banana pudding is one of my favorite desserts and the only way I can think to make it better is to add peanut butter.
Technique tips: Pipe each layer, instead of spooning it in, to ensure clean assembly. Layer this recipe in mini mason jars and screw the top back on for easy transport.
Swap option: Use vanilla wafers instead of peanut butter sandwich cookies.
For the banana pudding:
In a large bowl, mix the instant pudding, milk, sour cream, condensed milk and whipped topping together well. Chill until set and firm.
For the peanut butter mousse:
In a stand mixer (or with a hand mixer), beat peanut butter and softened butter on high for two minutes. Turn mixer to low and slowly add the powdered sugar.
In a 3-quart trifle dish or 9- by 13-inch glass baking dish, layer pudding mix, peanut butter mousse, sliced bananas and peanut butter sandwich cookies, ending with the cookies.
