Add the frozen berries, peanut butter, milk, and honey into your high-speed blender.
Secure the lid and blend on high for 30 to 60 seconds, until the mixture is smooth, thick, and vibrant in color, with no large berry chunks remaining.
Stop the blender and check the consistency; if it feels too thick, add a splash more milk and blend briefly to loosen it up.
Pour the thick, glossy mixture into a bowl, filling it generously to showcase its beautiful color and creamy texture.
Decorate the top with sliced bananas, granola, a drizzle of honey, or extra peanut butter for added texture and flavor.
Serve immediately with a spoon, savoring the cool, fruity, nutty flavors and textured toppings for a perfect breakfast treat.
