Why This Recipe Works

  • High protein breakfast. This high protein oatmeal is exactly that! High in protein! There are 28 grams of protein in this recipe. It’s such a delicious way to get that protein in right in the morning to keep you fuller longer.
  • Multiple sources of protein. This high protein breakfast has multiple sources of protein. The oats themselves contain protein, the peanut butter is packed with protein, plus the chocolate protein powder. The banana even brings a small amount of protein to this dish!
  • No bake oatmeal. Simply combine all the ingredients and let it sit overnight! It’s a no fuss, no bake oatmeal recipe! You don’t have to worry about taking the time to cook it on the stove or in the microwave. It’s ready to enjoy come the morning!
  • Tastes like a dessert! I’m convinced this protein oatmeal tastes like no bake cookies! Thankfully the recipe doesn’t have any refined sugar in it, though. In fact, they have a lot of similar elements like my chocolate peanut butter protein balls, but in breakfast form.

Ingredient Notes

  • Peanut Butter: Either regular peanut butter or natural peanut butter is fine to use. If you want a stronger peanut butter flavor, add some powdered peanut butter. See recipe tips for more on powdered peanut butter!
  • Maple Syrup: Use an imitation maple syrup or natural maple syrup based on preference.
  • Oats: Use old fashioned oats for the best texture. Old fashioned oats haven’t been chopped up into bite-sized pieces, which is essentially what instant/quick oats are.
  • Protein Powder: Any brand of chocolate protein powder will do.

Recipe Tips

If desired, you can replace the peanut butter with 1 T powdered peanut butter. You may need to add more milk to make the consistency more oatmeal like since you’d lose the creamy aspect from the peanut butter.

Powdered peanut butter is a great replacement if you are looking to lower the caloric value and fat content of the dish. Powdered peanut butter has the same amount of protein as normal peanut butter but has substantially lower fat content and about a third of the calories.

You can replace the maple syrup with honey if you’d prefer.

Flavor Variations:

  • Replace the chocolate protein powder for vanilla protein powder and add fresh berries on top for a peanut butter and jelly flavor.
  • Swap out the peanut butter for almond butter and add toasted coconut and almond slices for an almond joy overnight oats.

FAQs

What can I add to my oatmeal for more protein?

This recipe contains many sources of protein including peanut butter, protein powder, oats and even the banana brings in a small bit of protein! If you are looking to add more, you can add chopped nuts as a topping.

Which oats have the highest protein?

Rolled oats, steel cut oats and whole grain oats contain the same amount of protein. Some brands of protein oats are specifically made with added protein such as protein concentrate, whey protein, etc.

Do I have to let the oats sit overnight?

The nice part of this recipe is not having to cook the oatmeal. The only way to avoid cooking it is to let it sit overnight so the oats soak up the moisture and get that oatmeal texture. If you want to skip the overnight sitting, you could cook the oats and milk on the stove or in the microwave until they reach your desired oatmeal texture and then add the remaining ingredients and enjoy right away.
