This peanut butter oatmeal smoothie recipe is a healthy breakfast for weight loss and busy mornings! It’s creamy, easy to make, packed with fiber, and ready in 5 minutes. Combine a handful of pantry staples, like oats and banana, to create this nourishing breakfast smoothie. It’s vegan, gluten-free, dairy-free, and great for kids!


  • 1/2 cup rolled oats or quick oats
  • 2 frozen ripe bananas, peeled before freezing
  • 2 tbsp peanut butter
  • 12 tbsp maple syrup (optional but recommended)
  • 1 tbsp ground flaxseed (optional)
  • 1 tsp vanilla extract
  • 1 tsp ground cinnamon
  • 1/8 tsp salt
  • 1 cup oat milk (or any milk)


  1. Add all ingredients to a blender.
  2. Blend ingredients until smooth and creamy.
  3. Pour smoothie into glasses. Add an extra drizzle of peanut butter on top. Enjoy!


  • I recommend sweetening the smoothie with maple syrup, but you can also add medjool dates, honey, agave nectar, etc.
  • If you are gluten-free, double check the label on your oats to make sure they are certified gluten-free. Only use rolled oats or quick oats for this recipe. Do not use steel cut oats.
  • Since they are optional, the nutrition information does not include maple syrup and ground flaxseed.
