A filling banana oatmeal breakfast smoothie with oats, banana, and cinnamon, keeps you full for hours. ♡
This banana oatmeal breakfast smoothie is the filling 5 minute breakfast that replaces my morning bowl of oats when I am running late. Rolled oats, banana, almond butter, cinnamon, and milk blend into something that tastes like a bowl of banana oatmeal in a glass. For more ideas, see our Strawberry Banana Smoothie.
Easy, filling, genuinely fiber packed. The smoothie that keeps you full until lunch. Let’s make it together.
Ingredients
Banana Oatmeal Breakfast Smoothie
- 1/3 cup rolled oats
- 1 cup milk, whole or oat
- 1 large frozen banana
- 1 tbsp almond butter
- 1/2 tsp ground cinnamon
- 1 tsp vanilla extract
- 1 tbsp honey or maple, optional
- 1 pinch fine salt
How to Make Banana Oatmeal Breakfast Smoothie
- **Soften oats.** Add oats and milk to the blender. Blend 30 seconds to soften.
- **Add rest.** Add frozen banana, almond butter, cinnamon, vanilla, honey, and salt.

- **Check.** Add more milk if too thick.
- **Serve.** Pour into a tall glass.
- **Top.** Sprinkle with extra cinnamon and a banana slice. Serve immediately.
Why This Recipe Works
Using raw rolled oats (blended into the smoothie) adds 6g fiber without any cooking. The oats soften during blending and thicken the smoothie beautifully, creating that oatmeal texture without the cooking step.
Almond butter (or any nut butter) layers healthy fats plus extra protein. This combination with oats is what keeps this smoothie filling for 3-4 hours, unlike pure fruit smoothies that leave you hungry in an hour.
A generous pinch of cinnamon ties everything into classic oatmeal flavor. It mimics the flavor profile of a bowl of oats with brown sugar, just in liquid form. For more ideas, see our Green Detox Smoothie.
Tips
- Use rolled oats, not instant or steel cut.
- Blend oats first with milk for 30 seconds to soften them.
- Frozen banana for milkshake texture.
- Cinnamon is essential for oatmeal flavor.
- Store for up to 24 hours. Oats thicken over time.
- If too thick in the morning, shake with a splash of milk.
Variations
- Add a scoop of vanilla protein for 25g protein.
- Swap almond butter for peanut butter.
- Add berries for banana berry oatmeal.
- Stir in chia seeds for extra fiber.
- Add a date or maple drizzle for extra sweet.
- Top with granola and banana slices for a smoothie bowl version.

Common Mistakes to Avoid
- Instant oats: Rolled oats only. Instant turns gluey, steel cut stays crunchy.
- Fresh banana: Frozen banana is non negotiable for texture.
- Skipping the oat pre blend: Blend oats with milk 30 seconds first to soften.
- No cinnamon: Cinnamon is what makes it taste like oatmeal.
