Place the ripe bananas, peanut butter, and frozen berries into your blender. Close the lid and blend on high until the mixture is smooth, thick, and creamy, about 30 seconds. You'll notice a vibrant, purple-pink hue and a fragrant fruity aroma.
Pour the blended mixture into a bowl, using a spoon to spread it evenly. It should hold a slight mound and have a luscious, velvety texture that’s spoonable.
Use the back of a spoon or a toothpick to gently swirl a spoonful of berry jam into the surface of the smoothie. Create circular or figure-eight patterns, watching the vibrant jam streaks form and contrast beautifully with the creamy base.
Add your favorite toppings—sliced bananas, fresh berries, granola, or a drizzle of honey—on top of the smoothie bowl for added texture and flavor. Arrange them attractively for a visually appealing final look.
Serve immediately with a spoon in hand. The bowl should be cold, thick, and inviting, with colorful swirls and fresh toppings ready to enjoy.
