Add the bananas, peanut butter, berries, honey, and milk into the blender.
Blend on high speed for about 30 seconds, stopping to scrape down the sides if needed, until the mixture is thick, smooth, and creamy.
Check the consistency; it should be thick enough to mound when spooned. If it's too runny, add a few more frozen banana chunks and blend again briefly.
Scoop the smoothie mixture into a serving bowl, using a spoon to create an inviting mound.
Decorate the top with your favorite toppings—nuts, sliced fruit, fresh berries, and a drizzle of honey for extra sweetness and crunch.
Serve immediately with a spoon, enjoying the creamy texture and colorful toppings, capturing that childhood flavor in a nourishing bowl.
