Place two ripe bananas, frozen berries, peanut butter, and milk into your high-speed blender.
Blend on high for about 30-45 seconds until the mixture is silky, thick, and scoopable. You want it to be creamy with no large berry chunks.
Taste the smoothie and add honey if you'd like it a touch sweeter, then blend again for a few seconds to mix.
Spoon the thick, vibrant mixture into a bowl, smoothing the top with your spatula for an even surface.
Decorate the top with fresh fruit slices, a sprinkle of granola, and a drizzle of honey or jam for added sweetness and visual appeal.
Serve immediately with a spoon, enjoying the cool, creamy, and colorful flavors that evoke childhood comfort.
