High-Protein Peanut Butter Banana Oat Smoothie


  • Author: Thea
  • Total Time: 5 minutes
  • Yield: 1 serving 1x

Description

A thick, creamy, and high-protein smoothie made with frozen bananas, oats, peanut butter, and protein powder. It provides steady energy, keeps you full for hours, and requires zero cooking.


Ingredients

Scale
  • 2 medium frozen bananas, peeled and sliced (about 200g)
  • 1/2 cup old-fashioned rolled oats (40g)
  • 1 tablespoon chia seeds (10g)
  • 1 to 1 1/2 cups milk of choice (240-360ml)
  • 2 tablespoons natural peanut butter (32g)
  • 1 scoop vanilla protein powder (30g)
  • 1/2 cup ice (optional, about 50g)

Instructions

  1. Peel bananas, break into chunks, and freeze for at least 2 hours or overnight.
  2. Pour milk into the blender first to help the blades move freely.
  3. Add frozen banana chunks, rolled oats, chia seeds, peanut butter, and protein powder to the blender.
  4. Add ice if using.
  5. Blend on low speed, gradually increasing to high, for 45-60 seconds until completely smooth and oats are pulverized.
  6. Taste and adjust consistency by adding more milk if too thick or more ice/banana if too thin.
  7. Pour into a glass and serve immediately.

Notes

For best texture, use frozen bananas. If using a less powerful blender, soak oats in milk for 5-10 minutes before blending. This smoothie separates if stored, so drink fresh or blend again after storage. For meal prep, create dry ingredient packs to blend with milk in the morning.
