Banana Oat Breakfast Smoothie
A thick, creamy banana oat smoothie with Greek yogurt, peanut butter and cinnamon. A filling breakfast in a glass that takes 5 minutes.
When there is no time to sit down for breakfast, this smoothie keeps you full until lunch. Rolled oats add fiber and body, Greek yogurt adds protein, and a frozen banana makes it thick and cold without ice.
A spoonful of peanut butter, a little honey and a pinch of cinnamon make it taste like a bowl of banana oatmeal in a glass.
Everything goes into the blender at once, and it takes about 5 minutes from start to finish.

Oats: Old-fashioned rolled oats blend smoothly in most blenders. Blend them with the milk first if your blender is not very strong.

How to Make Banana Oat Breakfast Smoothie
Blend the oats
Add the oats and milk to the blender and blend for 20 seconds to break down the oats.
Add the rest
Add the frozen banana, Greek yogurt, peanut butter, honey and cinnamon.
Blend and serve
Blend on high for 45 to 60 seconds, until completely smooth. Add a splash more milk if it is too thick, then pour and serve right away.
Tips for the Best Results
- Soak the oats in the milk overnight in the fridge for an extra smooth texture.
- Add a handful of spinach; the banana hides the taste.
- Freeze bananas in slices so they blend easily.
- Use a straw-sized glass jar to take it on the go.
Common Mistakes to Avoid
| Mistake | How to fix it |
|---|---|
| Gritty texture | Blend the oats with the milk first. |

Substitutions

Frequently Asked Questions
Can you put raw oats in a smoothie?
Yes. Rolled oats are safe to eat without cooking and blend smoothly, adding fiber and body.
Is a banana oat smoothie a good breakfast?
It combines carbohydrates, fiber and protein from yogurt and peanut butter, which makes it more filling than a fruit-only smoothie.
Can I make it the night before?
Yes. Blend it, store it in a sealed jar in the fridge and shake well before drinking. Or soak the oats in milk overnight and blend in the morning.
How do I make it without yogurt?
Use more milk and add half a frozen banana or a scoop of protein powder for thickness.
