Overnight Protein Oats

I've been seeing lots of recipes online for "overnight oats," oatmeal breakfasts that are made overnight in the refrigerator (without cooking). I couldn't resist trying it with protein powder, so here you have Overnight Protein Oats!

My favorite way to make oatmeal is with almond butter and cinnamon, so that's what I've done here (with vanilla whey to boost the protein count!). I tried it with both rolled oats and quick-cook steel cut oats, and both worked well.

This recipe has created a new category here on the blog, Oats and Cereals. I look forward to experimenting with flavors and textures in overnight protein oats, and creating some cereal recipes as well!

These Overnight Protein Oats are especially great if you prep your meals in advance for the week, and are great to bring with you for a breakfast-to-go. Give them a try!

Prep Time 5 minutes mins
Cook Time 0 minutes mins
Total Time 5 minutes mins
Servings 1 serving

Ingredients

  • ⅓ cup filtered water about 3oz or 80ml
  • 1 tablespoon raw almond butter 15g
  • a dash of ground cinnamon
  • ¼ cup natural vanilla whey protein powder 23g
  • ¼ cup rolled oats 24g

Instructions
 

If you are making only one jar:

  • Put water, almond butter, and cinnamon in the jar, and mix it up.
  • Add whey powder, and mix well.
  • Add oats, and mix.
  • Let sit overnight (or at least 4 hours) in the refrigerator.
  • Stir and enjoy!

If you are making more than one jar:

  • Put one serving of oats in each jar.
  • Blend remaining ingredients, and pour over oats.
  • Stir the mixture in each jar so that the oats don't clump at the bottom.
  • Let sit overnight (or at least 4 hours) in the refrigerator.
  • Stir and enjoy!

Notes

A note about substitutions: You could substitute any kind of protein powder you like (for dairy-free/vegan versions), but you may need more water with other protein powders. Also, if you use quick-cooking steel cut oats, reduce the amount to 3 tablespoons (for this amount of liquid and these macros).

    Hi Theresa,
    Absolutely! In fact, it's great to make multiple servings for the week, too! Just make sure you're using a 16oz jar, so it will all fit!
    The double measurements are:
    2/3 cup water
    2 tablespoons almond butter
    a double dash of cinnamon
    1/2 cup whey protein
    1/2 cup rolled oats
    Enjoy!
    :)

    Can you double the recipe? I would like to make some for my son who would prefer a larger portion.

    Thanks, James! I suppose it would work with cream of rice, but you may need to adjust the water amount. Let us know if you try it! :)

    Hey I just wanted to say I can't wait to try this recipe with rolled oats! I was so happy I found it because it gives me more breakfast ideas especially being a teen bodybuilder! I was wondering if it would work with cream of rice ?
