Why it works
This is the chocolate banana smoothie after it joined a gym. Protein powder raises the protein to around 50g per serving, while the oats, banana and peanut butter keep it tasting like food rather than a supplement. Cocoa and chocolate protein together give a deep chocolate flavour that hides the powder well.
Mind the milk
Protein powder soaks up liquid, so you will need more milk than in a regular smoothie. Add it gradually while blending. If it gets too thin, a few ice cubes or more banana will bring it back. Blend for longer than feels necessary. Lumps of powder are nobody's idea of a good morning.
Swaps
Vanilla protein works if that is what is in the cupboard; add a little extra cocoa to keep it chocolatey. Almond butter can replace peanut butter. Pick a vegetarian protein powder, and if you use the vegan jar, a plant-based one keeps the whole drink dairy-free.
No DIY Oats jar?
Soak rolled oats in milk with chia and a few almonds overnight, then blend as above.
When to drink it
Straight after training is the usual slot. It is filling, at around 785 calories with 17g fibre, so treat it as a full meal, not a snack on the side.
Questions people ask
- How much protein is in this smoothie?
- By this recipe's numbers, one serving has around 50g protein, 785 calories and 17g fibre. The exact figure depends on your protein powder.
- Why is my protein smoothie too thick?
- Protein powder absorbs liquid. Add milk a little at a time while blending until it pours the way you like.
- Can I use any protein powder?
- Yes, as long as it is vegetarian. Chocolate flavour suits this recipe best, but vanilla with a little extra cocoa works too.
