This one is a classic — but when it’s done right, it never gets old. The peanut butter banana oatmeal smoothie is comforting, creamy, and actually filling, not just sweet and drinkable.
What makes the difference here is balance. Banana brings natural sweetness, peanut butter adds richness, and oats slow everything down so you don’t crash an hour later.
There’s a small trick at STEP 2 that improves both texture and satiety — and it works even without a blender.

Utensils
- 1 Hand immersion Blender or 1 mixing bowl
- 1 fork (to mash the banana)
- 1 whisk or spoon
- 1 measuring cup (or a simple glass)
- 1 tablespoon / teaspoon
- 1 serving glass or jar
Ingredients (1 serving)
- 1 ripe banana
- 30 g rolled oats (fine oats preferred)
- 1 tablespoon natural peanut butter (unsweetened)
- 200 ml milk or water
- 100 g plain yogurt or skyr (optional but recommended)
- 1 teaspoon chia seeds (optional)
Preparation
STEP 1
If using a blender, add the oats first and blend briefly to break them down.
STEP 2
If not using a blender, mash the banana thoroughly with a fork until very smooth.
👉 This step is key for a creamy texture without equipment.
STEP 3
Add oats, peanut butter, milk or water, yogurt, and chia seeds.
STEP 4
Blend until smooth or whisk vigorously until fully combined.
Why this works:
Oats slow digestion, banana provides natural energy, and peanut butter adds healthy fats that increase satiety. Yogurt or skyr brings protein for better balance.

FEATURED TOOL
Hand Immersion Blender
I recommend a hand immersion blender for this smoothie.
It blends oats and peanut butter directly in the glass or jar, gives a smooth texture without over-mixing, and saves time and cleanup.
It will arrive directly in your inbox.

2. Recipe Variations
- Vegan: use plant-based yogurt or skip yogurt
- Extra protein: add skyr or a neutral protein powder
- Lighter version: use water and reduce peanut butter slightly time slightly
3. Ultimate Tips
Use natural peanut butter only (just peanuts). Added sugar quickly turns this smoothie into dessert instead of a balanced meal.
