Equipment

  • Blender
  • Measuring cups
  • Spoon
  • Glass

Ingredients

  • ½–1 cup milk or plant-based milk
  • ½ cup rolled oats
  • 1 banana
  • 2 tbsp creamy peanut butter
  • 1–2 tsp honey or maple syrup
  • ¼ cup Greek yogurt
  • ½ tsp cinnamon or vanilla extract
  • ½ cup ice cubes

Instructions

  • Pour milk into the blender first to prevent oats from sticking.
  • Add rolled oats and peanut butter.
  • Add banana and any optional ingredients such as honey, yogurt, cinnamon, or vanilla.
  • Add ice if desired for a colder, thicker smoothie.
  • Blend for 30–45 seconds until creamy and lump-free.
  • Taste and adjust sweetness or texture as needed. Pour into a glass and serve immediately.

Notes

  • Use natural peanut butter for cleaner flavor and smoother texture
  • Rolled oats provide thickness and staying power; quick oats work in a pinch
  • Frozen banana will create a thicker, colder smoothie
  • Adjust milk for thinner or thicker texture
  • Optional add-ins like Greek yogurt, cinnamon, or vanilla enhance creaminess and flavor
  • Store in an airtight container in the fridge up to 24 hours; shake before drinking
