Blueberry Banana PB Smoothie

After a week away, getting back to my normal routine felt great — I started the morning with a short run and finished with this purple, protein-rich smoothie. It’s simple to prepare and easy to customize. If you like smoothies with a peanut-butter twist, other favorites include cacao or strawberry-peanut butter variations, but this blueberry-banana version is especially bright and refreshing.

Why this smoothie works

The banana adds natural sweetness and a creamy texture, frozen blueberries chill and thicken the drink while supplying antioxidants, and Greek yogurt plus PB2 boost the protein content without adding excessive fat. PB2 is a roasted peanut powder made from roasted peanuts with a small amount of salt and sugar; reconstitute it with water to make a lower-fat peanut butter alternative. Two tablespoons of PB2 provide peanut flavor with much less fat than regular peanut butter, making it a convenient option when you want the taste of peanuts but fewer calories from fat.

Notes and substitutions

  • If you prefer regular peanut butter, use about 1/2 tablespoon to keep calories and texture comparable to the PB2 version.
  • Milk choice can be swapped freely: use dairy, oat, or unsweetened almond milk depending on taste and dietary needs.
  • To increase protein further, add a scoop of your favorite protein powder or an extra 1/4 cup of Greek yogurt.
  • For a thinner smoothie, add a splash more milk; for a thicker, spoonable texture, add a few more ice cubes or a handful of frozen fruit.

Blueberry Banana PB Smoothie in a tall glass

Recipe

Prep: 5 mins   |   Cook: 0 mins   |   Total: 5 mins

Yield: 1 serving   |   Serving size: 1 tall glass

Ingredients

  • 1 medium banana
  • 1/2 cup fat-free plain Greek yogurt
  • 1/2 cup Fairlife 2% milk or plain unsweetened almond milk (or any milk of choice)
  • 2/3 cup frozen blueberries
  • 2 tbsp PB2 (powdered peanut butter) — or about 1/2 tbsp regular peanut butter
  • 1/2 cup ice

Instructions

  1. Place the banana, Greek yogurt, milk, frozen blueberries, PB2 and ice into a blender.
  2. Blend on high until the mixture is completely smooth, stopping to scrape down the sides if needed.
  3. Adjust consistency with more milk to thin or a few more ice cubes to thicken. Taste and adjust sweetness only if desired — ripe banana usually provides ample sweetness.
  4. Pour into a tall glass and enjoy immediately for best texture and flavor.

Tips for the best smoothie

  • Use a frozen banana or freeze slices beforehand for a thicker, colder drink.
  • To avoid a gritty texture from PB2, mix the powder with a tablespoon of water first to form a paste, then add to the blender.
  • Add a handful of spinach for extra greens — the mild flavor blends well with banana and blueberries and won’t affect the color too much.
  • If preparing ahead, store in the fridge up to 24 hours; shake or stir well before drinking as separation may occur.
