Ingredients You’ll Need
Below is a quick overview of what you’ll need to make the recipe and any substitutions you can make. Use the recipe card with the full list of ingredients and measurements at the bottom of the post when you’re ready to make the recipe.
- Frozen Banana: Don’t skip the frozen banana, it’s the key to a silky smooth, thick and frosty protein shakes! Extra frozen banana can be used in this Chocolate Banana Protein Smoothie or Peanut Butter Pumpkin Smoothie.
- 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)! If you have extra after making this, you can browse all nutritional yeast recipes here for ideas.
- 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. Feel free to add more peanut butter if you like! Peanut butter powder can also be used for a lower-calorie option.
- Milk: Any milk works here! Use soy milk, almond milk or oat milk to keep it vegan. Water is also fine in a pinch. You can use dairy milk if that’s suitable for you. Oat milk is the creamiest while almond milk or water are lighter.
- Protein Powder: Use any vanilla or chocolate protein powder. I prefer making this smoothie with vanilla protein but chocolate would make it like a chocolate peanut butter cup! If you want to double down on peanut butter, you could do a peanut butter flavor protein powder!
- Turmeric: Totally optional but adds a little boost of colour.
Nutritional Yeast in a Smoothie?
This smoothie has nutritional yeast which was inspired by my homemade peanut butter cup recipe. The nutrition yeast adds a salty, nutty flavour that makes it taste like a Reese’s Peanut Butter Cup. It’s technically optionally but I recommend giving it a try!
Variations and Extras
- Ground Flax or Chia Seeds: Add up to 1 tbsp for thickening, fibre and healthy fats.
- Hemp Seeds: Add up to 2 tbsp for healthy fats and extra protein.

To increase calories for a weight gain shake, add an additional 1-2 tbsp of peanut butter, half a frozen banana and additional milk as needed to reach your desired consistency. You can also add up to 1/2 cup oats, 3-4 dates or 2 tbsp chia seeds or ground flax.

Recipe Troubleshooting

FAQs
Sure! There are two ways to prep this smoothie in advance:
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.
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!
Sure! I really love the flavour and creaminess protein powder adds but here are some ways to replace it if needed:
Swap for 1/4 cup chickpeas or white beans.
Omit and add 1-2 tbsp cocoa powder and an extra half a banana.
Omit and add 3-4 pitted dates for sweetness.
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.
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:
Use steamed and frozen cauliflower or zucchini and an additional sweetener such as dates or stevia. Use frozen peach slices (this is my favourite no banana option).
Freeze dairy-free vanilla yogurt in an ice cube tray and use 4-5 of them to replace the banana.
Yes. You can freeze this shake in a freezer-safe container. Thaw in the fridge and blend again to improve the texture.
Yes. You can substitute 2-4 tbsp peanut butter powder like PB2 for peanut butter.

What does nutritional yeast give as a benefit? Isn’t the amount of protein in protein powder differ from one brand to another. Maybe you should write the recipe to say : use as directed by ur protein powder, or add protein powder to get 20 grms of protein. Mine is 15 grms per serving. Im not sure i have to add more or do the other ingredients add protein too?
Thanks
The peanut butter and nutritional yeast both add protein. The type of milk would also change the protein, for example soy milk provides about 8 g per cup whereas almond milk is only about 2 g. The nutritional yeast adds protein and B vitamins but it’s also for flavour, it adds a salty and nutty flavour like a Reese’s peanut butter cup. Nutritional facts are added as a courtesy and an estimate so if you need them to be very specific, I would suggest using something like My Fitness Pal or Cronometer and entering the exact ingredients you use if you need more precise nutrition facts. I used 30 grams of protein powder as listed in the recipe, which contained 20 g of protein. Thanks!
