Instructions
For the smoothest, silkiest texture, blend the oats on their own first until they turn into a fine flour before adding the rest of the ingredients. This extra step helps the oats mix more evenly into the shake, avoiding any grainy bits. It’s a quick trick that makes a big difference, giving your peanut butter protein shake a more velvety and refined finish.
To help your peanut butter mix smoothly into the shake, warm it slightly before blending. Just a few seconds in the microwave is enough to soften it, making it easier to combine with the other ingredients. This prevents clumps and ensures a creamy, even texture throughout the drink so you get that rich, nutty flavour in every sip.
Whether you enjoy your shake thick and spoonable or smooth and sippable, it’s easy to tweak the texture to suit your taste. For a thinner consistency, use a fresh banana, and swap a few ice cubes for the same amount of cold water. This will give you a lighter, more drinkable shake without changing the flavour. For an extra thick and creamy peanut butter protein shake, use a frozen banana instead of fresh. It adds natural sweetness and gives the shake a frosty, milkshake-like consistency without the need for extra ice. Just peel, slice, and freeze the banana in advance.
Questions about this peanut butter protein shake recipe
Here are some quick answers to common questions that might come up while making your peanut butter protein shake. From avoiding lumps to prepping ahead and storing leftovers, these tips will help you get the best texture and flavour every time.
Can I prep the ingredients ahead of time for easier mornings?
Yes, you can definitely prep the ingredients ahead of time to make blending even quicker. Peel and slice the banana, then portion it along with the oats, cinnamon, and peanut butter into individual containers. Store them in the refrigerator, and when you're ready, just add the skyr, milk, and ice cubes then blend. Just remember that prepping ahead may slightly change the texture, so give it a good blend to get everything smooth.
What’s the best way to store a peanut butter protein shake?
This shake is best enjoyed fresh, but the good news is that it only takes five minutes to make! For quicker prep, pre-portion the ingredients ahead of time. If needed, you can store the blended shake in the fridge for a few hours. To keep it frosty, skip the ice until just before serving, and give it a quick stir or blend if it separates. For longer storage, follow the same recipe but skip the ice cubes. Then freeze the shake in ice cube trays or popsicle moulds. When you're ready to enjoy it, blend the frozen cubes with the same amount of cold water you would have used for ice cubes – about eight cubes’ worth. This gives you a smooth, creamy shake straight from the freezer with minimal effort. Always use clean utensils and avoid leaving the shake at room temperature for more than two hours.
Why did my peanut butter protein shake turn out lumpy?
A lumpy shake is usually the result of ingredients not blending smoothly. Thick or cold peanut butter can clump, try warming it slightly before blending. Oats can also stay grainy if they’re not broken down enough, so consider blending them into a fine flour first. Make sure to add enough liquid, and blend on high until everything is fully incorporated. If your blender isn’t very powerful, blending in stages – starting with the oats and liquid – can help create a smoother result.

Top it off with peanut butter infused skyr
For a simple yet delicious topping, reserve a spoonful of skyr and a small amount of peanut butter from the recipe before blending. Stir them together until smooth, then dollop on top of your finished shake. It adds a rich, creamy finish with an extra boost of peanut flavour, no extra ingredients needed.
Out of cinnamon? Try these spice swaps instead
No cinnamon on hand? No problem, there are plenty of tasty alternatives to add warmth and depth to your peanut butter protein shake. Try a pinch of ground nutmeg for a subtle sweetness, or a dash of ground ginger for a gentle kick.
Cardamom offers a fragrant, slightly citrusy twist, while vanilla powder or extract brings smooth, mellow flavour. Start with a small amount and adjust to taste, these spices can go a long way.
Leftover oats? Try these protein shakes next
If you’ve got extra oats after making the peanut butter protein shake, put them to good use in one of these tasty, protein-packed drinks. Each offers a different twist, whether you're craving chocolate, fruit, or something extra creamy:
- Oatmeal protein shake: a richer, chocolatey alternative to the peanut butter version, with the same hearty texture from oats. Great if you’re in the mood for something more dessert-like.
- Banana oat shake: similar in flavour to this recipe but a little simpler, using basic pantry staples and a slightly milder taste.
- Protein mango smoothie: a fruity, tropical option that blends oats with a fresh mango base and tangy skyr for protein and creaminess.
- Cottage cheese smoothie: a tangy, protein-rich shake using cottage cheese and raspberries, offering a lighter texture and a refreshing change from nut-based shakes.
Is this peanut butter protein shake high in protein?
Yes, this recipe is high in protein, meaning that at least 20% of its energy comes from protein. This is primarily due to the creamy skyr and peanut butter. To boost the protein content even further, try substituting the skimmed milk with a protein-enriched milk, vanilla-flavoured works especially well in this recipe.
