Since I was a teenager, peanut butter banana smoothies have been my favorite dessert or snack. They’re creamy, sweet enough to satisfy my sweet tooth, and filling to serve as breakfast. I always have all the ingredients in stock. Plus, they’re INEXPENSIVE. If you’re looking to customize this banana smoothie, there are many ways.


If you can’t eat peanut butter for any reason or don’t want to, then feel free to substitute it with another nut butter. Sun Butter or Almond Butter would work well, but you could experiment with different flavored nut spreads. Remember to add the nut butter! It makes this smoothie more decadent and more delicious.

FROZEN Bananas have the best texture.

Frozen bananas are the key to achieving this milkshake-like texture. Frozen bananas will make your smoothie thicker and creamier, and keep it cold without adding ice. When I find bananas on their last legs, I peel them, slice them, and freeze them later in smoothies or other desserts.

Use any milk

This recipe for a smoothie is very flexible. This smoothie can be made with milk, dairy, or otherwise. Remember that the creamier your milk is, the lighter it will be. Coconut would be a great addition to these flavors, and I prefer whole milk.

What else can I add?

You can change the direction of this smoothie by adding different ingredients. Add these ingredients to banana smoothies:

Quick oats (about a quarter cup)



Ground flaxseed

Cocoa powder

Instant coffee

Chia seeds



One frozen banana, sliced ($0.22)

Peanut Butter 2 Tbsp ($0.14)

1 tsp Brown Sugar ($0.02)

1/4 tsp vanilla extract ($0.13)

One cup of milk is $0.20


Add the banana slices, peanut butter, and brown sugar to a blender.

Blend all ingredients until smooth. Add more milk if the smoothie is too thin. If your smoothie is too thick, you can add more frozen bananas. You can adjust the sweetness of your smoothie to suit your taste.
