Peanut Butter Banana Protein Smoothie
A thick, creamy smoothie that tastes like a peanut butter banana milkshake but fuels you like a proper meal. Frozen banana gives it a naturally sweet, ice-cream-like texture while peanut butter and protein powder make it surprisingly filling. Ready in 5 minutes flat.
For 2 servings
- prep
Slice and freeze the banana ahead of time.
Peel the bananas and slice them into 1-inch rounds. Arrange the slices on a plate or baking sheet in a single layer and freeze for at least 2 hours until solid. This gives the smoothie its thick, creamy texture without needing as much ice.
TIPFreeze bananas as soon as they develop brown spots — that's when they're sweetest. - mix
Combine all ingredients in the blender.

Blend until smooth and creamy.
Start on low speed and gradually increase to high. Blend for 30-45 seconds, pausing once to scrape down the sides with a spatula if needed. Stop when the smoothie looks thick, velvety, and no chunks of frozen banana remain.
TIPIf the smoothie is too thick, add a splash of milk and pulse briefly. If too thin, drop in another ice cube and blend again. - serve
Pour into glasses and serve immediately.
Divide the smoothie between two glasses. For a finishing touch, drizzle a tiny bit of peanut butter on top or add a few banana slices. Enjoy right away while cold and frothy.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use overripe bananas with brown spots for maximum natural sweetness and a creamier texture.
- 2Freeze banana slices in a single layer on a tray to prevent them from clumping together.
- 3Add the milk before the frozen bananas to help the blender start more easily.
- 4If your smoothie is too thick, add milk 1 tablespoon at a time and pulse to thin it out.
- 5For an extra-cold smoothie without diluting flavor, replace ice cubes with additional frozen banana pieces.
- 6Make a double batch and store leftovers in the fridge for up to 24 hours — shake or stir before drinking.

Frequently asked questions
You can, but the texture will be thinner and less creamy. If using fresh banana, add a few extra ice cubes and expect a drinkable, not thick, smoothie.
