Only six ingredients are needed to make these delicious keto peanut butter balls. In addition to peanut butter itself, almond flour, keto-friendly protein powder, and some fun mix-ins make up the rest of the ingredients needed.
Here’s what you’ll need:
- Keto-friendly protein powder – I chose to use a vanilla protein powder for a mild flavor.
- Natural peanut butter with no added sugar – make sure to stir the peanut butter well when you measure to ensure the natural oils are mixed in.
- Almond flour – this helps bind everything together while keeping the protein balls keto.
- Flax seeds
- Pumpkin seeds
- Macadamia nuts – this is optional, but I recommend giving it a try.

Peanut butter lovers rejoice: very little prep is needed to make keto protein balls!
The only ingredient that might need a bit of prep is your macadamia nuts if you opt to add them.
I wasn’t able to locate crushed macadamia nuts, so I put the large chopped pieces of nuts in a bag and broke them into small pieces with a rolling pin.
Of course, if you are not using macadamia nuts, then you can skip this step.
Combine the protein powder, almond flour, flax seed, pumpkin seed, and peanut butter in a food processor. Pulse several times until your protein ball mixture is crumbling.
Add a spoonful of water to the protein ball mixture and combine. Continue to add water to one spoonful at a time until the mixture is sticking together, about 3-4 spoonfuls of water.
Scoop the peanut butter mixture using a tablespoon and form them into a ball.
Roll each ball in crushed macadamia nuts if desired.
Set the ball aside and repeat forming the balls until you have formed 18 keto protein bites.
Hint: if the macadamia nuts don’t want to stick to your protein balls, dip the ball in water or almond milk and then roll in the crushed nuts. The water will help the nuts stick to the protein balls without making them sticky.

I used a food processor to help me mix up these peanut butter energy balls, but it is not necessary. I mostly used the food processor so that it would chop up my pumpkin seeds for me.
If you prefer, you can mix the protein balls in a bowl with a mixing spoon. Keep the pumpkin seeds whole or crush them like the macadamia nuts.
Your keto protein balls should be stored in the refrigerator in an airtight container for up to a week.
The energy balls can also be stored frozen and defrosted a few at a time. Frozen protein balls will stay good for 3-6 months in the freezer.
Your keto protein ball mixture will be dry when you first mix it. Adding water a spoonful at a time will help your mixture stick together when forming into balls.
If you are having a hard getting the crushed macadamia nuts to stick to the balls, dip them in water and then roll them in the nuts. This will help the nuts stick without making the protein balls mushy.
