Gather all your ingredients and place them on your kitchen counter for easy access.
In your blender, combine the frozen mixed berries, ripe banana, plain yogurt, milk, and peanut butter. Blend until smooth and creamy. If your smoothie is too thick, add a little more milk to reach your desired consistency.
Taste your smoothie and adjust the flavors if needed. You can add more peanut butter for nuttiness or a little honey if you prefer it sweeter.
Pour the smoothie mixture into a bowl, creating a nice base for your toppings.
Top your smoothie bowl with fresh berries, sliced bananas, granola, coconut shavings, additional raisins, seeds, and chopped nuts. Get creative and arrange them in a visually appealing manner.
Grab a spoon and dig into your vibrant berry smoothie bowl with banana. Enjoy the delightful flavors and textures!
