3-Ingredient Peanut Butter Protein Balls

These 3-Ingredient Peanut Butter Protein Balls are the perfect protein-packed snack – all you need is oats, nut butter and protein powder!

Ingredients and substitutions

Rolled oats – quick oats and large flake oats would also work. Steel cut oats won't work well with this recipe as they haven't been flattened. If you find yourself cooking with oat flour a lot, feel free to substitute your oats with oat flour.
Protein powder – protein powder is a key ingredient to this recipe. If whey protein doesn't sit well with you, then feel free to replace this alternatives like soy protein, rice protein or pea protein.
Peanut butter – if you have a peanut allergy, substitute the peanut butter for any other nut or seed butter.

Choosing a protein powder

There are a lot of protein powders available on the market, which can be overwhelming if you are buying one for the first time.

When choosing a protein powder for these 3 ingredient peanut butter balls, use these tips:

Choose a whey protein that has the fewest ingredients. Tip: protein should be the first ingredient.
Select a powder that has 25-35 grams of protein per serving.
Make sure it is low-carb – preferably less than five grams.
Look for a protein powder without any added sugar or artificial sweeteners.
Always choose the protein isolate. This means it contains more than 90% protein.

Here is the protein powder I use if you're looking for a clean one. Whey protein is made from dairy so if you are vegan or lactose-sensitive you may want to opt for a vegan protein powder such as soy, pea or rice.
