- Blend until smooth and thick.
- Taste-test: adjust sweetness if needed.
- Pour into a tall glass (or shaker bottle if you’re on the go).

- Nut-free: Use sunflower seed butter or tahini instead of peanut butter.
- Extra chocolatey: Add 1 tsp cocoa powder.
- Boost omega-3s: Add 1 tbsp chia seeds or ground flaxseed.

❄️ Storage & Solo Tips

- Short-term: Store in a shaker bottle in the fridge for up to 12 hours. Shake well before drinking.
- Prep hack: Freeze peeled bananas in chunks – no more black bananas going to waste.
💡 Plan4One Extra Tips
- Buy a jar of natural peanut butter and keep it as a pantry staple – it works in smoothies, on toast, or even in savoury stir-fries.
- Use oats sparingly – ¼ cup makes it filling without turning it into wallpaper paste.
- If your blender struggles with oats, soak them in the milk for 5 minutes before blending.
