Ingredient notes

You’ll need three ingredients to make peanut butter oatmeal balls:

  • Salted natural peanut butter — you’re looking for a peanut butter with just peanuts and salt on the ingredients list (the salt is important to balance flavors)
  • Old fashioned oats — these give the best texture, but you could sub for quick oats if needed
  • Vanilla protein powder — pick one without added sugars

Step-by-step instructions

Mix dough: Add all ingredients to a large mixing bowl, including optional mix-ins. With a wooden spoon or spatula, mix ingredients together until well combined.

They should form a thick dough that easily stays together when pressed. Adjust the ingredients as needed until dough has reached your desired consistency (see notes).

Form balls: Grab about 2 Tbsp of dough and use your hands to carefully form balls. Place on a plate, making sure balls aren’t touching each other. Repeat until all dough has been used.

Store: Refrigerate for 1-2 hours before transferring to a food container with a lid. Store in the fridge for up to five days.

Optional mix-ins

If you want, you can add a few tablespoons of extra mix-ins.

In the recipe, I suggest mini chocolate chips or M&M’s candies. These mix-ins are super tasty but will add some sugars to this otherwise sugar-free snack.

Other mix-in options can include raisins, dried cranberries, sugar-free chocolate chips, shredded coconut, or chopped dates.

Tips and tricks

  • Use a small cookie scoop to measure your dough before forming balls
  • Use a tasty protein powder because you’ll definitely taste it
  • Squeeze your measured dough in your hands before rolling into balls (this helps them stay together)
  • Prep these peanut butter oatmeal balls on Sundays to enjoy all week

Common questions

Can I use chunky peanut butter?

I would recommend using smooth peanut butter instead of chunky for this recipe so the balls form together more easily.

Is this recipe plant-based?

This recipe can easily be made plant-based by using a plant-based protein powder.

What if my dough is too thick?

If your dough is too thick, add more peanut butter. You’ll also need to make sure you’re using fresh natural peanut butter that’s a little “drippy”. If your peanut butter is dry, the balls won’t form properly.

What if my dough is too thin?

If your dough is too thin, add more protein powder and/or oats.
