Original recipe for 4 servings

2 ripe bananas
40 g rolled oats
400 ml milk
1 tbsp honey

Step by step

Follow the timeline: technique icon, time and temperature when relevant.

Step 1 Cut

Peel ripe bananas and cut into chunks. Frozen banana makes the smoothie creamier without ice.
Step 2 Blend

In the blender, add milk first, then banana, oats and a pinch of cinnamon. Blend on high speed for 45-60 seconds until no oat lumps remain.
Step 3 Blend

Taste and adjust: if too thick, add a little more milk; for a colder drink, add 2-3 ice cubes and blend 10 seconds more. Serve immediately.

Storage

Best eaten the same day. Leftovers keep refrigerated up to 24 hours.

Chef tips

Very ripe bananas (speckled skin) sweeten the drink without added sugar.
Soak oats 10 minutes if your blender is not very powerful.
You can prep it the night before and refrigerate up to 12 hours.

Variations

Substitutions for a vegan version

Instead of: 400 ml milk

Use: same amount of unsweetened oat milk (or soy for béchamel)

Why: Milk adds liquid, fat and dairy sweetness; plant milk keeps texture without casein.

Tip: Choose oat for creams and soy for binding sauces. Heat gently—do not boil hard or it may split.
Instead of: Honey

Use: same amount of agave or maple syrup

Why: Honey sweetens and adds moisture; plant syrups do the same without animal products.

Tip: Reduce slightly if the syrup is sweeter. In baking, browning will be similar.

Other variations

Add fresh fruit or nuts.
