Ingredient Notes

Visual of list of ingredients needed for making a peanut butter protein shake.
  • frozen banana – don’t skip the frozen banana, it’s the key to a silky smooth shakes! See below for making it without banana.
  • nutritional yeast – nutritional yeast is the secret ingredient in this shake, it adds the perfect salty, nutty flavour plus extra protein and B12 (if it’s fortified)!
  • peanut butter – use your favourite natural peanut butter, for a peanut-free smoothie, swap it for almond butter or for a nut-free smoothie, swap it for sunflower seed butter
  • milk – any milk works here! Use your favourite nut, seed, soy or oat milk to keep it vegan.
  • protein powder – I like Vega, North Coast Naturals, PVL, Outcast Mission and Iron Vegan but any works, you can use vanilla or chocolate protein powder. See below for making it without protein powder.
  • turmeric – totally optional but adds a little boost of colour and mild spiced flavour

FAQs

Can you make this in advance?

Sure! There are two ways to prep this smoothie in advance.

1. Add sliced banana, peanut butter, protein powder and nutritional yeast to a bag or container and freeze. When you’re ready to make the smoothie, dump into a blender, add milk and blend.

2. Make in advance and store overnight in the fridge. It won’t be as thick as drinking it fresh but it will still be delicious!

Can I make this without protein powder?

Sure! I really love the flavour and creaminess protein powder adds but here are some ways to replace it if needed:

1. Swap for 1/4 cup chickpeas or white beans.
2. Omit and add 1-2 tbsp cocoa powder and an extra half a banana.
3. Omit and add 3-4 pitted dates for sweetness.
4. Omit and add 2 tbsp chia seeds to help thicken.

If you make it without protein powder and it’s not sweet enough for your, sweeten to taste with dates (or date paste), a touch of maple syrup or a sugar-free sweetener such as stevia or monk fruit.

Can you make this without banana?

You can! This shake is definitely best with frozen banana but if you have an allergy or dislike it, here’s how you can make the shake without banana:

1. Use steamed and frozen cauliflower or zucchini and an additional sweetener such as dates or stevia.
2. Use frozen peach slices (this is my favourite no banana option).
3. Freeze dairy-free vanilla yogurt in an ice cube tray and use 4-5 of them to replace the banana.
