A creamy 3 ingredient peanut butter banana smoothie, the easiest breakfast in 5 minutes. ♡

This peanut butter banana smoothie is the 3 ingredient breakfast I make when I have zero motivation and zero groceries. Frozen banana, natural peanut butter, and milk. That’s it. Thick, creamy, and tastes like a milkshake. For more ideas, see our Strawberry Banana Smoothie.
Easy, no protein powder needed, and naturally sweet from banana. The purest peanut butter banana flavor. Let’s make it together.

Ingredients
Peanut Butter Banana Smoothie
- 2 large frozen bananas
- 2 tbsp natural peanut butter
- 1 cup milk, whole, oat, or almond
- 1/2 tsp vanilla extract, optional
- 1 pinch cinnamon, optional

How to Make Peanut Butter Banana Smoothie
- **Liquid.** Pour milk into the blender.
- **PB.** Add peanut butter.
- **Banana.** Add frozen bananas, broken into chunks.

- **Blend.** Blend 60 seconds until silky thick.
- **Serve.** Pour into a tall glass. Drizzle with extra peanut butter. Serve immediately.
Why This Recipe Works
Frozen banana is the single ingredient that makes this 3 ingredient smoothie work. Frozen transforms banana into creamy ice cream texture, delivering sweetness and thickness at the same time. Fresh banana makes a thin bland smoothie.
Natural peanut butter (just peanuts and salt) carries all the peanut flavor without interference. Reduced fat or sugar added peanut butter tastes processed and flat. Use the good stuff.
Whole milk or oat milk delivers enough fat to carry the PB flavor and create that milkshake mouthfeel. Skim milk tastes watery in this simple recipe. Fat is a feature here. For more ideas, see our Green Detox Smoothie.
Tips
- Always frozen banana for milkshake texture.
- Use natural peanut butter only. Reduced fat throws off the flavor.
- Oat or whole milk for the richest smoothie.
- Add a pinch of cinnamon for extra warmth.
- If too thick, add milk 1 tbsp at a time.
- Store in the fridge for up to 24 hours. Shake before drinking.
Variations
- Add a scoop of vanilla protein for 25g+ protein.
- Blend in 1 tbsp cocoa for chocolate PB banana.
- Add a date or drizzle of honey for extra sweet.
- Swap PB for almond butter, cashew butter, or sunflower seed butter.
- Add a handful of spinach for hidden greens.
- Top with banana slices and a drizzle of PB for dessert presentation.

Common Mistakes to Avoid
- Fresh banana: Frozen only. Fresh makes thin smoothie.
- Reduced fat PB: Natural only. Reduced fat has fillers and sugars.
- Skim milk: Whole milk or oat milk. Skim tastes watery.
- Under blending: Blend 60 seconds until completely smooth.
