Why I like this smoothie
Peanut butter and banana are a classic combination, and oats give this smoothie a little more substance. Milk and Greek yogurt round out the ingredients.
I originally developed this recipe as a way to use foods available through WIC, including milk, yogurt, peanut butter, oats, and banana. It works for breakfast or a snack, depending on the amount that fits your needs.

How to make it
- Put the ingredients into a blender (affiliate link).
- Blend for 30–60 seconds, or until smooth.
- Pour into two cups and enjoy.
Preparation tips
- Want it colder? Slice and freeze the banana beforehand, or add the optional ice.
- Making one serving? Use half of each ingredient amount.
- Choose your texture: Blend until the oats and banana are smooth.

Variations
The original recipe uses low-fat milk and plain nonfat Greek yogurt. You can use the milk and yogurt you prefer; the flavor, texture, and nutrition may change.
Ground flaxseed is optional. Use the full amount, half the amount, or leave it out according to your preference.
Fit it into your day
The recipe makes two servings, so I often split it with my kids. Use your appetite and needs to decide what amount works for you. For help with that, see my portion size guide.
