Ripe bananas and natural peanut butter create a salty-sweet flavor combo in this protein-packed Peanut Butter Banana Oatmeal Smoothie. It’s perfect for breakfast or any time of the day.

Aside from maybe chocolate, few foods taste better with freshly-roasted, salty peanut butter than a perfectly ripe banana. And aside from maybe pancakes, the best breakfast consists of smoothies. My Peanut Butter Banana Oatmeal Smoothie combines the best of both worlds and is morphed into a well-rounded breakfast thanks to yogurt, milk, and oats.

Ingredients
- Banana: Naturally sweetens the smoothie and adds a creamy texture.
- Milk: Use whatever milk you have on hand, any and all will work.
- Greek yogurt: Greek yogurt is higher in protein than typical yogurt, and adds to the creamy texture of the smooothie.
- Oats: I use old-fashioned oats, and they make the smoothie more filling while being a great source of fiber, calcium, and iron.
- Peanut butter: A huge source of protein, while also being creamy, delicious, and nutty.
- Cinnamon: Sweet and woody in flavor, cinnamon is a great way to get many antioxidants.
Easy Substitutions
- Make it dairy free. Use almond or oat milk and swap the yogurt out for a dairy free substitute.
- Up the protein. Add a scoop of your favorite protein powder to really pack in the protein punch on this smoothie.
