Peanut butter banana smoothies have been a favorite snack (or dessert) of mine since I was a teenager. I usually always have the ingredients on have on hand, they’re ultra-creamy, just sweet enough to kill my sweet tooth, and filling enough to stand in for breakfast. Plus, they’re INEXPENSIVE. There are a lot of ways you can modify this simple banana smoothie if you want to make it your own, so if you haven’t tried this one yet, definitely put it on your list!
Use any Nut Butter
I love the classic peanut butter-banana combo, but if you don’t like peanut butter or can’t have it for other reasons, feel free to substitute it with any type of nut or seed butter. Almond butter or Sun Butter would be awesome, and it would also be fun to experiment with flavored nut butters. The nut butter makes this smoothie extra rich and delicious, so don’t skip this ingredient!
Use Frozen Bananas for the Best Texture
The key to getting this ultra-creamy milkshake-like consistency is to use frozen bananas. Not only will frozen bananas make the smoothie extra thick and creamy, but they also keep it cold without having to add ice, which would water down the smoothie. So anytime I have bananas that are on their last leg, I make sure to peel, slice, and freeze them to use in smoothies and other desserts later.
Use Any Type of Milk
This smoothie recipe is incredibly flexible. You can use any type of dairy or non-dairy milk for this smoothie, keeping in mind that the creamier the milk, the creamier the smoothie will be. I like whole milk the best, but I think coconut would also pair nicely with these flavors!
What Else Can I Add?
As mentioned above, there are a lot of different things you can add to this smoothie to take it in a different direction. Try adding some of these ingredients to your banana smoothie:
- Quick oats (about ¼ cup)
- Ground flaxseed
- Cocoa powder
- Instant coffee
- Chia seeds
